The following topics are covered in this section:

• The HP StoreOnce Backup System (page 6)

• Types of user account (page 6)

• Deployment of the Virtual Storage Appliance

• Navigating the StoreOnce Management Console (GUI) (page 7)

• Navigating the online help (page 9)

The HP StoreOnce Backup System

The HP StoreOnce VSA extends the StoreOnce portfolio with the agility and flexibility of StoreOnce
as a virtual appliance, removing the need to install dedicated hardware.

StoreOnce VSA delivers a flexible backup target for service providers and organizations with an
ITaaS (IT as a service) infrastructure; rapidly stand-up the StoreOnce VSA configured for up to
10TB of additional capacity, and retire it again when the capacity is no longer needed to regain
the resources for other uses. In multi-tenant environments, one StoreOnce VSA per tenant also
provides security of backup data between tenants.

Once installed and powered on, StoreOnce VSA is used by backup and recovery applications as
a backup target, in the same way as physical StoreOnce appliances and delivers the following
benefits:

• Exceptional value: Install into an existing vSphere (v5.x) environment without the need for

specific hardware. The StoreOnce VSA is available to purchase by license, which includes
HP StoreOnce Catalyst support, for seamless data movement across the enterprise, and
Replication support, to enable it to be used as a replication target.

• Easy to manage—locally: StoreOnce VSA can be managed using a local graphical interface

(GUI) or the StoreOnce Enterprise Manager application. The local GUI is the same, well
proven interface used to manage the HP StoreOnce Backup appliances and provides a
consistent experience for enterprise-wide deployments.

• Easy to manage—across the enterprise: For users with multiple StoreOnce appliances and

multiple StoreOnce VSAs, StoreOnce Enterprise Manager (SEM) enables centralized
management. Through the centralized StoreOnce Enterprise Manager up to 400 combined
total StoreOnce physical appliances/virtual appliances can be managed across multiple sites.
As well as advanced monitoring, reporting, forecasting and trend analysis, HP StoreOnce
Enterprise Manager can be used to deploy and configure StoreOnce VSA appliances.

• Rapid installation: Installation and configuration is simple and typically completed in less than

15 minutes—StoreOnce VSA can be deployed using either SEM or via a vSphere client.

Types of user account

There are two types of user account: admin and user. Two users, one for each account type, are
created automatically when the system is installed:

• Administrator: This account allows authorized users to create and edit management and

StoreOnce functions via the GUI and CLI. The initial user name and login is Admin and admin,

6 Getting started

but the Admin user may change this via the GUI or CLI. Any password change applies to both
the GUI and CLI.

• Operator: This account is available if the administrator wishes to provide limited access to the

GUI and CLI to certain users whose access will be restricted to monitoring and viewing. The
initial user name and login is Operator and operator, but the Admin user may change this
via the GUI or CLI.

After installation, a user with an Admin login may set up additional user accounts and assign a
role (admin or user) and password to these users. See User Management (page 111).

NOTE: There is a third account reserved for HP Support to which no other users have access.

However, it is important to know that the HP Support user can only gain access to this account via
the Admin login.

Tip

To find out what type of user rights you have, look at the title bar. This shows your User Name and
User Role. See (page 8).

Deployment of the Virtual Storage Appliance

HP StoreOnce VSA is a software-only version of the HP StoreOnce Backup System. Packaged as
a virtual appliance, it can be deployed and run on a vmware vSphere hypervisor (v5.x) installed
by the customer. Once deployed, the customer has access to the StoreOnce Management Console
for both Web Management via the GUI and command line management via the CLI. The StoreOnce
VSA Backup System supports 10 x 1 TB virtual disks.

The customer is able to create the following backup target devices on the HP StoreOnce VSA:

• Catalyst stores

• iSCSI VT libraries

• CIFS NAS shares

The virtual appliance is fully compatible with StoreOnce hardware products for replication and
Catalyst Copy functions and is fully integrated within HP StoreOnce Enterprise Manager, both for
ease of management and for ease of deployment.

There are two methods of deployment:

• Using StoreOnce Enterprise Manager, SEM 1.0

• Using vSphere Client (v5.x)

Instructions for deployment are in the HP StoreOnce VSA Deployment and Configuration guide.
Please consult the guide to deploy your StoreOnce VSA backup system.

Navigating the HP StoreOnce Management Console (GUI)

The HP StoreOnce Management Console is the main interface for:

• Monitoring the status and health of the HP StoreOnce Backup system and all configured backup

devices

• Creating and modifying VTL and NAS StoreOnce backup targets and Catalyst stores

• Managing replication relationships and housekeeping

To run the StoreOnce Management Console

To log on using the StoreOnce Management Console, use any machine connected to the
management network. The HP StoreOnce Backup system uses a secure network connection.

Enter: https://<IP_address>

Deployment of the Virtual Storage Appliance 7

NOTE: If you use http: in the URL, you are automatically forwarded to the https: secure network

connection.

The StoreOnce Management Console displays the Login prompt.

NOTE: The web browser used to communicate with the StoreOnce Backup system must have

Active Scripting or JavaScript enabled. If it does not, some of the browser buttons may not be
displayed.

GUI components

The GUI display has the following sections:

• Title bar: This section shows the user name and role. It also contains the Logout and Help

buttons.

8 Getting started

NOTE: After a period of 15 minutes of user inactivity the session will time out and return to

the Login screen.

• System Status (top left side panel): This section shows you the last time the system was updated

(this is the machine time) and a count of event status categories over the last 24 hours.
Three icons are used in the System Status area. To view the individual events for more detail,

select Events from the Navigator, as described in Events log (page 119).

Indicates standard information.

Indicates a warning state. Something needs attention but it is not critical to the successful operation of
the device. For example, a disk may have failed or disks may be installed in an expansion shelf but
not licensed.

Indicates a critical state. Something needs attention. Investigate immediately. This warning icon may
appear in the Details area of the screen with a red square background (rather than a red circle), it has
the same meaning.

• Navigator (left side panel): This displays the available GUI topics and allows you to navigate

to the appropriate topic page. A + sign next to a topic indicates that it has more options below
it. Click on + to expand the selection, and on — to contract the selection.

• Topic page (main window): When you first log on, the main window shows the top-level

StoreOnce topic page for your product. Once you select another topic from the Navigator,
it displays the appropriate page for that selection. Some Topic pages require you to select an
item, such as a library, NAS share or Catalyst store, in the top half of the page to view details
that are specific to the selected item in the lower half of page. Some Topic pages have multiple
tabs within the page, for example the VTL-Libraries page. When you select a tab, information
and actions appropriate to that tab are displayed.

Navigating the online help

The Help button in the top right-hand corner of each page displays context-sensitive information
for the current page.

In the following example we have selected Help from the NAS page.

• The Help window can be resized in the normal way; click and drag on a side or a corner to

expand or contract the window.

• The information in the header shows you where the help has been called from. Hyperlinks

allow you to move to the next or earlier pages (NAS in our example).

• The information in the footer also provides navigation options. If you select home you will be

taken to the Home page for the help, which gives you access to the complete online user
guide. From this page you also have Contents, Search and Index options. You will need to
resize the page to use it effectively.

Navigating the online help 9

The StoreOnce CLI

The StoreOnce Command Line Interface (CLI) provides an alternative way of administering and
monitoring the system. Some tasks can only be carried out from the StoreOnce CLI.

StoreOnce CLI commands require an SSH client application (freely available from the internet) and
must be run from a SSH terminal session:

ssh <username>@<ip_address>

Two users are created at installation: Admin and Operator. Users with an Admin login can create
additional users after installation. See User Management (page 111).

See the StoreOnce CLI Reference Guide for more information about the StoreOnce CLI commands.

Licensing

There is single All-in-One License that supports StoreOnce Catalyst, Replication and Write. At
deployment an Instant-On All-in-One feature license is automatically applied that is valid for 60
days. This license should be converted to a full, perpetual license before it expires.

At the end of the 60-day period, your data is still secure on the HP StoreOnce VSA, but its status
is changed to read-only until you add and apply the full license. The Read-Write status is restored
as soon as the full license is applied, even if this is after the 60-day period. There are no time
constraints on when the full, permanent license may be applied.

See the HP StoreOnce VSA Deployment and Configuration guide for detailed information on how
to obtain and apply a full license.

10 Getting started

3 VTL (Virtual Tape Libraries) functions

The following topics are covered in this chapter:

• VTL page (page 14)

• Libraries page (page 14)

• Make Replication Target libraries visible to the host (page 26)

VTL Configuration page

Select VTL from the HP StoreOnce menu item to display the current VTL configuration.
The HP StoreOnce – VTL page has the following tab(s):

• iSCSI Settings tab (page 14)

NOTE: There are equivalent StoreOnce CLI commands available for the tasks described in this

section. Please see the HP StoreOnce Backup system CLI Reference Guide.

iSCSI Settings tab

By default, a new library is automatically created whenever a new server first connects to the HP
StoreOnce Backup system using the iSCSI initiator. Users with an Admin login may use this page
to disable this feature.

Click Edit and make sure the Auto Creation Enabled box is unchecked.

Libraries page

Click VTL — Libraries in the Navigator panel to display the libraries that have been created.
The top half of the Libraries page shows all libraries configured for the appliance. Click on a library

to display its details in the lower half of the page. Users with an Admin login may edit these settings
or delete libraries. They may also create new libraries.

VTL devices are iSCSI libraries.

14 VTL (Virtual Tape Libraries) functions

The lower half of the Libraries page contains four tabs that show information relevant to the selected
library:

• Device details tab (page 16)

• Interface information tab (page 20)

• iSCSI Authentication tab (page 21)

• Active Connections tab (page 21)

• Cartridges tab (page 22)

Working with the Libraries list (top half of page)

The Libraries list in the top half of the page provides up to 10 columns of details.

• To sort the list according to a column, click on the column heading and select Sort Ascending

or Sort Descending.

• To hide or show columns, click on any column heading, select Columns and uncheck or check

the required columns.

• Users with an Admin login may also create libraries. Click Create.

See Create a library (page 17) for more information.

Table 3 Libraries parameters (top half of page)

DescriptionParameter

This is the name that is used to identify that device (library). It is often helpful to use a
name that identifies the host or backup job with which it is associated.

Name

This is the role of the library, which may be non-replicating, replication source or
replication target.

Replication Role

This is the status of the library, which may be online, offline, notstarted, failed to start,
stopping, creating or deleting.

Status

This indicates whether the library is connected. Possible values are: Connected – A client
device is connected to any device (robotics or drive) within this library. Not Connected
– No device is connected to this library.

Connection

This is the emulation type used by the backup software. It is selected when you create a
device.

Device Type

This is the number of slots available on the device, which is determined by the Emulation

types for tape device selected when the device was created. You can reduce the number

Slots

of slots in the Device Details tab for a library selected on this page, but this will only
remove the highest empty slots. Once it reaches a slot number that contains data, it will
not allow you to reduce the number further on this page, even if earlier slots are blank.
You must first use the Cartridges tab to make the slot empty.

This is the actual size on disk (after deduplication).Size on disk

This is the deduplication ratio achieved on the data on the library.Dedupe ratio

Device Details tab

This tab shows device information for the selected library.
Users with an Admin login may carry out the following tasks from this tab:

• Create a library (page 17)

• Edit a library (page 18)

• Delete a library (page 19)

• Make Replication Target libraries visible to the host (page 26)

Table 4 Device Details tab

DescriptionField

This is the name that is used to identify that library. You may like to enter a name that
identifies the host or backup job with which it is associated.

Library Name

This is the emulation type of the library. The HP StoreOnce Backup system supports a number
of emulation types, see also Emulation types for tape device (page 19). The emulation type

Emulation Type

determines how many embedded drives and cartridge slots are available. For example, if
you select HP MSL G3 Series (2x24), the device will emulate an MSL 2024 Library with two
embedded tape drives and a possible total of 24 cartridge slots. Consult your backup
application technical support information for further details.

By selecting a drive emulation type, HP LTO–2, 3, 4 or 5, you set only the default capacity
of the cartridges within the library device. (LTO-2 = 200 GB, LTO-3 = 400 GB, LTO-4 =

Drive Emulation

800 GB, LTO-5 = 1.6 GB.) It does not affect the ability of the backup application to write
to the device and tape cartridge capacities can be increased at any time (but not decreased),
as long as the cartridge is blank, regardless of the drive generation number.
If you have selected D2DBS Generic for the Library Emulation Type, you will be able to
select Ultrium VT for the drive emulation. This is a generic Ultrium device which is clearly
identifiable as virtual. Backup application support for Ultrium VT is reasonable, but not quite
as complete as the D2DBS library type, so its not possible to use it with all backup software.

This is where you define the number of slots that you require for your tape rotation strategy.
The number of slots available depends upon the Emulation Type that you have selected.

Total Number of
Cartridge Slots:

Each slot will be automatically populated with a new cartridge upon creation whose capacity
is appropriate to the Drive Emulation type.
You can change the maximum size of the cartridge as long as it is blank. This means that
you can only change the value immediately after the device is created and before it has
been accessed by the backup application.

16 VTL (Virtual Tape Libraries) functions

Table 4 Device Details tab (continued)

DescriptionField

The default number of drives is determined by the Emulation Type that you have selected. If
you increase the number of drives be careful not to exceed the maximum number of libraries
and drives that a host can physically access.

• 64 for iSCSI interfaces

Number of Drives:

Data deduplication is enabled by default for the library device. It is not possible to disable
deduplication on any HP StoreOnce Backup system.

Deduplication:

This is the date that the library was created and is generated automatically.Creation time:

This identifies the network port on the HP StoreOnce Backup system to which the device is
connected. This will be the port used for the Library device as well as the default port for
embedded tape drives.
The number of ports available in the drop-down menu depends upon your network
configuration. There is always an iSCSI port. This is configured using the StoreOnce CLI

Port:

net config commands. (See the HP StoreOnce Installation and Configuration guide for
more information.)

This option allows you to select whether the barcodes for the library should display six or
eight characters. The HP StoreOnce Backup system generates barcodes automatically for

Number of Barcode
Characters:

cartridges. If you enter a barcode manually, you must always enter 8 characters. If the
6–character barcode is selected, the StoreOnce Backup system will truncate to the top six
characters, removing the top two characters of an 8–character barcode, i.e. barcode
1ABCDEFG will truncate to BCDEFG. The barcode is displayed with the truncated characters
in brackets on the Cartridges tab, (1A)BCDEFG.

This is the Initiator Node Name of the host that will back up to this device. You must enter
it manually when you are creating a new device. If you are using the Microsoft iSCSI Initiator,

iSCSI Initiator Name:

(iSCSI devices only)

you can find the name by running the iSCSI Initiator on the host and copying the Initiator
Node Name from the General tab.

To create a new library (administrators only)

It is recommended to:

• Only configure the libraries that you need

• Only configure the number of cartridges that you are likely to need

NOTE: Refer to the HP Best Practices for VTL, NAS, StoreOnce Catalyst and Replication

implementations, available on the HP Manuals web site, for guidelines on setting up a backup

policy/job within backup applications. This will also help you determine how many libraries and
cartridges you need to set up.

You can add cartridges at a later date to expand the system and remove individual blank cartridges
from a library without deleting the whole library, but cannot remove cartridges that have been
written to.

1. To create a new library device for the host, click on Create.

Libraries page 17

2. Enter the appropriate details in the Device details tab (page 16) and click Create. The

Cartridges tab is only generated after the library is created. The information on the Interface
Information tab is normally generated automatically.

Guidelines on creating libraries

The maximum number of virtual devices supported is split across VTL, NAS, and Catalyst devices.
The table below illunstrates maximum configurations for libraries and drives, but this number may
be limited if you have already created NAS shares and Catalyst stores. For more detailed device
configuration examples, refer to the HP Best Practices for VTL, NAS, StoreOnce Catalyst and
Replication Implementations.

To edit library details (administrators only)

It is possible to edit some, but not all, device details after creating a library. In particular, you
should be aware of the following:

• You can delete cartridges by reducing the number of slots on the Devices page, but this will

only remove the highest—numbered empty slots. Once the Delete operation reaches a slot
number that contains a cartridge, it will not allow you to reduce the number further on the
Details page, even if earlier slots are empty. You must first use the Cartridges tab to delete
the cartridge from the slot.

• If you change the cartridge size (by changing the emulation type) on this page, this will only

change newly-added cartridges; it does not change the size of cartridges that have already
been created.

• You can reduce the number of drives but, if you go to 0, the port setting will go to "No Port".

• You cannot change the library type to a type that has a smaller set of maximum values (e.g.

number of cartridges) than is currently set.

18 VTL (Virtual Tape Libraries) functions

1. Select the device in the list to display its details and then click on Edit.

2. Amend details as appropriate and click Update to apply them.

To delete a library (administrators only)

Select the required device and then click on Delete in the Details section to delete it. You will be
prompted to confirm that this is what you wish to do.

WARNING! All data on the device will be deleted. The library's deduplication store is also

deleted. It may take some time to delete all the files and free space on the HP StoreOnce Backup
system.

Emulation types for tape devices

HP StoreOnce Backup systems emulate a range of physical tape devices, which are listed below.

Table 6 Emulation types for tape devices

DescriptionEmulation type

If it is supported by your backup application, this is the preferred emulation type because it
does not emulate any physical library types in existence and is, therefore, clearly identifiable

D2DBS Generic Library:

as a StoreOnce device. It is the most flexible emulation type available; however, backup
application support varies by software vendor.

If you have selected D2DBS Generic for the Library Emulation Type, you will be able to
select Ultrium VT for the drive emulation. This is a generic Ultrium device which is clearly
identifiable as virtual. Backup application support for Ultrium VT is reasonable, but not quite
as complete as the D2DBS library type, so its not possible to use it with all backup software.

NOTE: Symantec prefer their customers to use this emulation type with BackupExec and

Netbackup.

This is a tape library device with a maximum of two embedded Ultrium tape drives and 24
cartridge slots. It should be used when implementing rotation schemes which involve

MSL G3 series (2x24)
Library:

simultaneous backup jobs to two devices. This emulation type is widely supported by backup
applications.

This is a tape library device with a maximum of four embedded Ultrium tape drives and 48
cartridge slots. It should be used when implementing rotation schemes which involve

MSL G3 series (4x48)
Library:

simultaneous backup jobs to more than two devices or those that use a large number of
cartridges devices. This emulation type is widely supported by backup applications.

Libraries page 19

Table 6 Emulation types for tape devices (continued)

DescriptionEmulation type

This is a tape library device with a maximum of four embedded Ultrium tape drives and 96
cartridge slots.

MSL G3 series (8x96)
Library:

This is an enterprise tape solution which allows you to configure up to 200 drives per node
and up to 4096 cartridges per library.

ESL-E series Library:

This is an enterprise tape library solution which allows you to configure up to 200 drives
per node and up to 4096 cartridges per library.

EML-E series Library:

Flexible emulation

The ESL, EML and D2DBS emulations are particularly flexible because they allow you to configure
a large number of drives per library. This has two main benefits:

• It allows for more concurrent streams on backups which are throttled due to host application

throughput, such as multi-streamed backups from a database.

• It allows for a single library (and therefore dedupe store) to contain similar data from backups

that must run in parallel to increase deduplication ratio.

If using these flexible emulation types, the following factors should also be considered:

• An important consideration when configuring VTL devices is that the library and each drive

that you configure for it counts as a separate device. There are practical limitations on the
number of devices that each host or HBA can access.

For iSCSI VTL devices a single Windows or Linux host can only access a maximum of 64
devices. A single library with 63 drives is the most that a single host can access. Configuring
a single library with more than 63 drives will result in not all devices in the library being seen
(which may include the library device). The same limitation could be hit with multiple libraries
and fewer drives per library.

• The total device value also applies to NAS shares and Catalyst stores. If you configure the

full value as VTL devices, you will not be able to configure any NAS shares or Catalyst stores
for that appliance.

• Please refer to the HP Best Practices for VTL, NAS, StoreOnce Catalyst and Replication

implementations for maximum and recommended values.

Interface Information tab

This tab shows interface information for the media changer and drives on the selected library.
The information for the Interface Information tab is generated automatically and changing it is not

recommended.
The following information is provided for a device that is configured to use the iSCSI interface.

20 VTL (Virtual Tape Libraries) functions

Table 7 iSCSI Interface Information

DescriptionField

The device name lists all of the devices for the specific Library. There will be an entry for the
Medium Changer, and for each of the drives configured.

Device Name

This defines the port to which each media changer or drive is connected.Port

This is a unique serial number for the device. It is generated automatically by the HP
StoreOnce Backup system and cannot be edited.

Device Serial Number

This is provided when the device is created.World Wide Node Name

This is generated automatically by the HP StoreOnce Backup system for iSCSI devices.iSCSI Target Name

This is generated automatically by the HP StoreOnce Backup system for iSCSI devices.iSCSI Alias

iSCSI Authentication tab

If required, this tab should be used to configure iSCSI CHAP authentication. Click Edit and provide
the required details.

Table 8 iSCSI Authentication Information

DescriptionField

Check this box if you require the initiator to logon. You must also provide the Initiator CHAP
user name and secret.

Require initiator to logon

This should be the same CHAP user name that you configure for the target on the iSCSI
Initiator. (On the Microsoft iSCSI Initiator, this is the User Name as it is configured on the
Targets tab in the Log On to Target Advanced Settings.)

Initiator CHAP User
Name

This should be the same CHAP secret that you configure for the target on the iSCSI Initiator.
(On the Microsoft iSCSI Initiator, this is the Target Secret as it is configured on the Targets
tab in the Log On to Target Advanced Settings.)

Initiator CHAP Secret

Check this box if you require mutual CHAP authentication, which means that the target must
also log on to the initiator. You must also provide the target CHAP user name and secret.

Target required to logon
to initiator

On the iSCSI Initiator you must also make sure that mutual authentication is enabled. (On
the Microsoft iSCSI Initiator, make sure Perform mutual authentication is checked on the
Targets tab in the Log On to Target Advanced Settings.)

This may be any meaningful CHAP user name. It does not need to match any information
on the iSCSI Initiator.

Target CHAP User Name

This should be the same CHAP Secret that you configure for the target on the iSCSI Initiator.
(On the Microsoft iSCSI Initiator, this is the Secret as it is configured from the General tab.)

Target CHAP Secret

Active Connections tab

This shows the Session information of any active connections to the library; it displays information
about open iSCSI sessions. All details are generated automatically and cannot be edited.

If a device is showing as not connected, this indicates that the iSCSI Initiator on the host has not
logged on. Log on using the iSCSI Initiator and set the device as a Persistent Target for that host.
This ensures that it will automatically log on again whenever the host is rebooted.

Libraries page 21

Cartridges tab

This tab shows cartridge information for the selected library.
Users with an Admin login may carry out the following tasks from this tab:

• Create a cartridge (page 23)

• Delete a cartridge (page 24)

• Write protect a cartridge (page 25)

• Edit maximum cartridge size (page 25)

• Move or unload a cartridge (page 26)

Table 9 Cartridge tab parameters

DescriptionField

The Location column identifies each element of the library that is available to hold a cartridge.
There are three types of element:

Location:

• Mail slot: which is a dedicated slot that is used to hold a cartridge that is ready for

exporting to or importing from physical tape. It is not used with HP StoreOnce products.

• Tape drive: which is populated when there is activity on a cartridge. You can also move

a cartridge into a tape drive by using the Move Cartridge drop-down menu in Edit mode.

• Slot n: which is one of the standard library slots

A barcode is an 8– or 6–digit, alphanumeric, unique identifier for a cartridge within the HP
StoreOnce Backup system. Barcodes are shared with the backup application, if requested.

Barcode:

The backup application may also choose to assign its own internal identifier to the cartridge
but, if it does so, it cannot assign this identifier to the Cartridge barcode.
Barcodes are generated automatically but may be edited by the user. If you choose to edit
the barcode:

• It must be unique and must not start with the letters “CLN” or “DG” because these are

reserved designations for cleaning and diagnostic cartridges.

• It should be a minimum of 6 characters. Valid ASCII characters are A-Z, a-z, 0–9.

Barcodes will always be shown as 8 characters with letters in capitals on the StoreOnce

22 VTL (Virtual Tape Libraries) functions

Table 9 Cartridge tab parameters (continued)

DescriptionField

GUI and CLI (padded with space characters) regardless of the size selected. However,
if the Number of Barcode Characters is set to 6, only the rightmost 6 characters will be
made visible to the backup software, i.e. barcode 1ABCDEFG will truncate to BCDEFG.
(Truncated barcode characters are shown in brackets in the Cartridges tab.)

This checkbox indicates whether the slot is included in a replication mapping configuration.
It cannot be edited from this page.

Mapped Slot:

This shows the actual used capacity in MB or GB.Used Size:

This defaults to the appropriate capacity for the drive emulation type selected on the Devices
tab. This value may be changed if the Used Size is Blank, see below. The maximum value
allowed is 3200 GB.

Max Size:

This is a check box that allows you to enable (checked) and disable (unchecked) write
protection, see below.

Write Protected:

This tells you when the cartridge was last written to and is useful when identifying data for
copying or exporting.

Last Written:

NOTE: Additional columns appear when function buttons are selected below, such as Create,

Move, Delete.

Empty slots

Empty slots are slots that contain no cartridges; all the fields are empty.

• Tape drive row: A library consists of two devices; a tape drive and changer device. This

location refers to the tape drive element of the library. It is normally only populated when the
backup application on the host is writing to or reading from the library.

• Mail slot row: This location refers to the slot that is used for importing and exporting data to

a physically attached tape drive. It is not used with HP StoreOnce products.

• Numbered slot row: This slot is empty after a Delete operation or after the backup application

has moved data to the mail slot for export.

Once a numbered slot is empty, the Create button may be used to create a new, blank cartridge.

To create a cartridge (administrators only)

NOTE: You can only create a cartridge in an empty slot.

Click on the Create button. There is a new right-hand column, Add Cartridge. Slots that are empty
have a checkbox in this column.

You can select individual slots by clicking in the appropriate checkboxes. When you have selected
the slots where cartridges should be added, click Create.

Alternatively, click Create all to create a blank cartridge of the size/emulation type selected when
the library was first configured in all empty slots.

Libraries page 23

• If you create a cartridge in an empty slot, the backup application needs to inventory it (add

it to its database or catalog) before it can access it.

• If you create a cartridge in an empty mail slot, you can use the backup application to move

the blank, new cartridge to an empty cartridge slot, without having to run an inventory. This
saves some processing time.

You may need to restart your backup application services to see the new cartridges.

To delete a cartridge (administrators only)

To delete an individual cartridges, click on the Delete button. There is a new right-hand column,
Delete Cartridge.

You can select individual slots by clicking in the appropriate checkboxes. When you have selected
the slots where cartridges should be deleted, click Delete.

Alternatively, click Delete All to delete all the cartridges in the library. This option prompts you to
confirm that all cartridges should be deleted, warning you that mapped slots in replication targets
will not be deleted. If this is OK, click Delete All. If not, use Delete Blank.

24 VTL (Virtual Tape Libraries) functions

NOTE: You can also delete cartridges by reducing the number of slots on the Devices page, but

this will only remove the highest blank slots. Once the Delete operation reaches a slot number that
contains data, it will not allow you to reduce the number further on the Details page, even if earlier
slots are blank. You must first use the Cartridges tab to make the slot blank.

To write protect a cartridge (administrators only)

1. Click Edit for the selected library.

2. Check the Write Protected check box for the cartridge(s).

3. Click on Update. Your backup application will not be able to write any more data to the

cartridge(s).

To edit maximum cartridge size (administrators only)

The Max Size defaults to the appropriate capacity for the drive emulation type selected on the
Devices tab, but you can edit this value. The maximum value allowed is 3200 GB.

NOTE: The maximum size indicates the maximum amount of user data that can be written to that

cartridge, assuming uncompressed data; it will only be committed when data is written to it.
Changing the maximum space does not affect actual disk usage or save disk space, but may be
useful if you know you will be moving data to a physical tape with a smaller cartridge capacity.

1. Click Edit for selected library.

Libraries page 25

2. Select a value from the drop-down menu and click Update.

To move or unload cartridges

The ability to move cartridges is provided, but only to an empty Location (tape drive or numbered
slot).

• Click on the Move button. There is a right-hand column, Move Cartridge. The Move Cartridge

drop-down menu lists available empty slots. (Empty numbered slots are created if you delete
a cartridge.)

• Use the Unload all Cartridges button to return all cartridges to their slots.

The move and unload options are unlikely to be required very often, but may be useful if the user
needs to re-align their library configuration against their backup application should they become
out of sync, perhaps because the backup application has crashed, or if the backup application
does not support the Move Medium command.

Making Replication Target libraries visible to the host

NOTE: See Replication functions (page 40) for more details on replication configuration.

Replication Target libraries are not normally visible to the host, but you can configure devices to
make them visible to backup applications. This allows the backup application to:

• Move cartridges from storage slots to drives in the library

• Perform read and verify operations on the cartridge (but not write)

• Perform load/unload operations on the tape device

WARNING! This facility should be used with care. If the backup application can see both source

and target libraries, it will not be able to distinguish between the source library and the target
library because the barcodes are duplicated in the two locations.

26 VTL (Virtual Tape Libraries) functions

Why make target libraries visible?

There are two occasions when it may be useful to make a target library visible to the backup
application on the host.

• To confirm that replication is working correctly and check the integrity of the replicated backup

by doing a test restore

• To perform manual tape copy jobs to any tape device on the network using the backup

application

IMPORTANT: You cannot change data on a Target library cartridge; you may only load it

temporarily into a physical tape device to read it.

Best practices for using this feature

WARNING! If you do not follow these best practices, unstable and possibly damaging results

may occur. Cartridges may be marked as unusable or the backup application may attempt to write
to target cartridges.

• Ensure that no replication jobs to the selected target cartridge are in progress

• Ideally check that no backup jobs to the mapped source cartridges are scheduled

• Ensure that the backup application media server instance to be used is not within the same

cell/domain that can access the source cartridge

• Import the data on the target cartridge into the backup application (this operation must be

repeated after each replicate operation to the cartridge)

• Perform the desired operation on the cartridge, which may be:

Verify the cartridge using the backup application either using a verify command or by
performing a restore

◦

◦ Copy the cartridge to a physical tape device connected to the media server

How is a target device made visible?

1. Create the replication mapping, as normal. See Running the replication wizard (virtual tape

devices) (page 57), as appropriate.

2. From the host that has access to the target library, on the VTL — Libraries page select the
target library in the Libraries list.

3. Click Edit.

4. The Port defaults to None. Select the appropriate port.

5. Click Update.

6. Now you can make the target library visible from other hosts. Target visibility persists even if
the power fails or if the replication mapping is removed.

NOTE: To remove target visibility, simply reset the Port to None.

Making Replication Target libraries visible to the host 27

4 NAS functions

This page provides access to the following StoreOnce NAS functions:

• NAS Configuration (page 28), which allows users to configure CIFS servers and permissions

• Shares (NAS) (page 36), which allows users to view and manage NAS shares

NAS Configuration page

Select NAS from the StoreOnce menu item to display the NAS configuration page.
On the NAS configuration page, you can configure a CIFS Server for your shares.

• The CIFS server provides CIFS interface shares that provide backup targets to Windows servers,

see CIFS Server tab (page 28)

NOTE: With the current version of the software there are no equivalent CLI commands available

for the tasks described in this chapter.

CIFS Server tab

There are two configuration stages when creating a backup target share that Windows users can
access; both stages are implemented from the Web Management Interface:

• Configure authentication for the StoreOnce Backup system CIFS server, these settings then

apply to all NAS CIFS shares created on it.

• Create NAS CIFS shares on the HP StoreOnce Backup system, see Creating a CIFS

share (page 37).

Configuring the CIFS server

1. Select NAS on the StoreOnce Management Console.

2. Select the CIFS Server tab.

3. If required, click Edit to modify the authentication settings.

There are three authentication options that provide different levels of security for CIFS NAS
shares: None (default), User, and AD (Windows Active Directory). Before configuring the
settings, make sure you know which is appropriate for your network and any extra information
that may be needed during configuration.

28 NAS functions

• None (no authentication)

Setting authentication to None provides a simple CIFS server configuration that allows
for the creation of shares with no authentication. Any user or computer can mount and
access the shares created on the HP StoreOnce Backup system with this setting.

• User authentication

Setting authentication to User provides a method of securing the CIFS shares so that they
can be accessed only by specified users local to the CIFS Server. Once the server has
been set to User mode, it is possible to create new local users by selecting Create User.

See “Configuring user authentication” (page 30) for detailed instructions.

• Active Directory (AD) authentication

Setting authentication to AD allows the CIFS server to join a Windows Active Directory
domain. Access to individual CIFS shares is then managed from the Windows domain
controller server which can provide the names of domain users that will have access. See

Configuring CIFS Server with AD and CIFS Share with AD domain users (page 31) for

detailed instructions.

4. Make changes, as required, and click Update. You will be advised that if you update the CIFS
Server settings, any backup or restore jobs in progress for it will fail.

5. Click Continue (or Cancel).

NOTE: When switching authentication modes the user must log out and back into the

Windows client before the new authentication settings will work.

6. You are now ready to create CIFS NAS shares, see Creating a CIFS share (page 37).

Connecting to the NAS target device on Windows

To access the NAS CIFS target device from a Windows server on the network, enter in Windows
Explorer:

<StoreOnce server name>/<share name> or <IP address>/<share name>.

CIFS Server tab 29

It is also possible to connect using \\<Fully Qualified domain name>\<share name>.

• If User authentication was set for the CIFS server, you will be prompted to enter a user name

and password, which will be:

<StoreOnce server name>\<user name> <password> or <StoreOnce IP
address>\<user name> <password>.

The share can also be mounted through the Map Network Drive utility in Windows or through
the Command Prompt utility with the net use command.

net use z:\\192.168.2.1\Share_3 /user:192.168.2.1\User1<password>

This will mount Share_3 available from StoreOnce device 192.168.2.1 locally on the server
on z: drive using local StoreOnce CIFS server User1 credentials.

• If AD authentication was set for the CIFS server, you will be prompted to enter a user name

and password, which will be:

<Domain name>\<user name> <password>

The share can also be mounted through the Map Network Drive utility in Windows or through
the Command Prompt utility with the net use command.

net use z:\\192.168.2.1\Share_3 /user:192.168.2.1\User1<password>

This will mount Share_3 available from StoreOnce device 192.168.2.1 locally on the server
on z: drive using the ‘mydomainname’ domain user User1 and its credentials.

Configuring user authentication

Creating a new user and setting permissions

Once the server has been set to User mode, it is possible to create new local users.

1. On the CIFS server tab, select Create User.

2. Provide a user name and password and click Update.

These users can then be individually allowed to access any of the shares that are created.
When creating a new user in User Authentication mode, the user must log out and back into
Windows before they can access the newly created share.

30 NAS functions

3. Navigate to HP StoreOnce-NAS-Shares to provide individual users access to specific shares.
Create a NAS CIFS Share; on the Permissions tab it shows No Access.

4. Click Edit and change it to Access. Click Update. Confirm the update by clicking Yes.

5. In Windows, navigate to Computer, right click and select Map Network Drive.... Specify the

drive letter for connection and the network path of the share.

6. Enter the user credentials.

7. This provides the user with access to the share.

Deleting a user

1. To delete a user you must first disconnect the mapped share.

2. On the StoreOnce-NAS-Shares page display the Permissions tab for the Share and edit it to
be No Access.

3. Navigate to the StoreOnce-NAS—CIFS Server tab. You can now select the user and click
Delete.

4. Click OK. The user no longer exists.

Configuring CIFS Server with AD and CIFS Share with AD domain users

Prerequisites

• Domain Name

• Domain Controller running:

Windows server 2003◦

◦ Windows server 2003 R2

◦ Windows server 2008

◦ Windows server 2008 R2

• User account on Domain Controller, which should be the Domain Administrator or Delegated

user with Domain Administrative rights

• User account on server running DNS to add entries

• The system time on the StoreOnce Backup system must be correct and in sync with that of the

domain controller. Using the StoreOnce CLI NTP commands on the StoreOnce Backup system
to synchronize with a time server is a good way to ensure accurate time keeping. See the HP
StoreOnce Backup system CLI Reference Guide for more details.

IMPORTANT: AD Domain Support: StoreOnce products support configuration in a multi-domain

tree forest but does not support multi forest domain topologies.

Configuring CIFS Server with AD and CIFS Share with AD domain users 31

Adding the StoreOnce device to an AD Domain

In order to join a domain:

1. Connect to the StoreOnce Web Management Interface and navigate to the NAS -> CIFS Server

page

2. Select the Edit button and choose AD from the drop-down menu.

NOTE: An entry for the StoreOnce appliance must be created in the DNS server such that

the appliance can be resolved using its domain qualified appliance name.

3. Provide the name of the domain that you wish to join, for example “mydomain.local”

4. Select Update. If the domain controller is found, a popup box will request credentials of a

user with permission to join the domain. (Note that joining or leaving the domain will result
in failure of any backup or restore operations that are currently running.)

5. Provide the credentials (<Domain Name>\< User Name> and <Password>) of the Domain

Administrator or a delegated user with Domain Administrative rights and select Register.

6. After a short delay (the time is dependent on the topology and size of the AD Domain) the
computer will become a member of the domain and a Success dialog is displayed.

32 NAS functions

7. Launch the “Active Directory Users and Computers” management tool (type dsa.msc from
the command line or launch from Administrative Tools) to check that there is an entry for the
StoreOnce device CIFS server and that the StoreOnce Backup system can be “managed”
(Action -> Manage from the menu) by the domain.

Managing shares on an AD domain

Now that the HP StoreOnce Backup system is part of a domain and can be managed, it is possible
to create shares and grant access permission to them for domain account users or groups.

NOTE: The StoreOnce appliance only supports the Shared Folders utility within the Windows

Computer Management. Any other Windows Computer Management utilities are not supported.

1. Firstly create a share on the Backup system that is going to be used as a backup target, by
selecting NAS -> Shares from the Web Management Interface and clicking Create.

2. Provide a share name and description, then select the CIFS protocol and click Create.

Configuring CIFS Server with AD and CIFS Share with AD domain users 33

3. The share will start and its status will change to Online.

4. It is now necessary to provide a list of users that can access this share, this is done from the

Windows Computer Management tool. Select the Shared Folders -> Shares option to display
the available shares on the StoreOnce Backup system. In addition to the user configured shares
there will be two “default shares” called C$ and IPC$, these cannot be used for backup.

5. Now select the newly created Backup share and select Properties from the Action menu.

34 NAS functions

6. Select the Share Permissions tab and Add a user or group of users from the domain, then
specify the level of permission that the users will receive. Finally select Apply.

7. Now from any Windows server on the domain it is possible to access the newly created share
using the credentials of anyone who had been given permission to access the share. If a
permitted user is logged into Windows, access to the share will be granted automatically with
those permissions.

NOTE: When switching from None or User authentication mode to AD authentication mode,

it is recommended that the user logs out and back into the Windows client where the share
is mounted. This will ensure the new authentication settings of the CIFS server are enforced.

NOTE: The HP StoreOnce Backup system does not support creating shares from Windows

Computer Management Consoles. Shares must be created from the StoreOnce Management
Console.

Configuring CIFS Server with AD and CIFS Share with AD domain users 35

Leaving an AD Domain

The user may wish to Leave an AD domain in order to:

• Temporarily leave then rejoin the same domain

• Join a different AD Domain

• Put the StoreOnce Backup system into either No Authentication or Local User Authentication

modes.

If the user wants to leave, then rejoin the domain there is the option on the NAS — CIFS Server
GUI page to Leave AD, the user can then rejoin the same domain. If joining a different AD domain
or changing mode, the user should select the Edit button on the page and select the new domain
or mode.

Shares (NAS)

This page is used to view and manage all NAS target devices (referred to as shares).

NOTE: It is important to understand that the HP StoreOnce network share is intended to be used

ONLY by backup applications that “back up to disk”. Do not use the NAS target device as a
drag-and-drop general file store. The one exception to this rule is if you are using the NAS share
to seed an appliance for replication.

Creating NAS shares

Users with an Admin login may create NAS shares. See also:

• CIFS: Creating a CIFS share (page 37)

Editing share details

Users with an Admin login may edit the Description and Write Protection settings for existing NAS
shares.

1. Select the share on the Shares page and click Edit.

NOTE: The field, Network Path, is not displayed when you select Edit.

2. Make the required changes and click Update.

36 NAS functions

3. You will be advised that if you update the Share settings, any backup or restore jobs in progress
for it will fail. Click Yes (or No).

When the changes are applied they will take effect immediately. If the NAS server (service)
needs to restart, there will be a warning provided to the user, which they can accept to allow
all shares to temporarily go offline. Note that you cannot change the share name once it has
been created.

If a share is converted from Read/Write to Read Only, any open items will be force closed
which may result in inconsistencies if they are being written to by a backup application. The
user will be warned that this could occur before the change is made.

Deleting share details

Users with an Admin login may delete a share.
Select the share in the list and click Delete.

Creating a CIFS share

A note about permissions

Each share also has a Permissions tab. The options available on this tab depend upon the type of
Authentication that you selected when you configured the CIFS Server.

• If No Authentication was selected, the Permissions tab is disabled.

• If User Authentication was selected, there will be a list of users and you may set the access

permissions for that share for each user in the list to Access or No Access. See Configuring
user authentication (page 34) for a worked example.

• If AD Authentication was selected, share permissions are managed from the AD Domain. See

Configuring CIFS Server with AD and CIFS Share with AD domain users (page 39) for a
worked example.

Shares (NAS) 37

1. Select NAS — Shares on the StoreOnce Management Console and display the Shares tab.

2. Click Create.

3. Provide the following information:

• Name: the name that will be used to identify the share in Windows.

• Description: a text description of the share (optional)

• Access Protocol: Select CIFS

The Network Path is provided by the Management Console in the format:
<IP address>/<share name>.
It is also possible to connect using:
\\<Fully Qualified domain name>\<share name>.
There is also an option to enable Write Protection. This should only be used if you want to

prevent further backup to the share. If you enable it, any backup jobs currently using that
share will fail.

4. Click Create. It will take a few minutes for the status of the new share to go Online.

5. If using User Authentication, select the share in the Shares list and display the Permissions

tab, this will show the list of users available on the server who can be assigned access to NAS
target devices. You may amend click Edit and permissions for individual NAS target devices.

6. The NAS target device is now available as a network drive and you can target it from the
backup application. It can also be mapped as a network drive in Windows.

NOTE: The NAS target device is not optimized for general purpose file storage. The HP

StoreOnce Backup system is a NAS deduplicating appliance that is optimized for backup.

If you are new to replication we strongly recommend that you read the following documents, which
are available from the HP web site. They provide a detailed discussion about replication deployment
strategies and terminology and include examples using the Replication and Recovery wizards.

• HP Best Practices for VTL, NAS, StoreOnce Catalyst and Replication implementations: This

guide also describes best practices and includes examples using different backup applications.

NOTE: A license is required for replication on the target appliance.

What is an appliance?

Replication can take place between multi-node, single-node, and single-node VSA StoreOnce
Backup systems. The GUI for both refers to both Replication Targets and Sources as appliances.
It is important to understand the different meaning of appliance within the multi-node, single-node,
and single-node virtual environments.

• In a single-node StoreOnce Backup system, the appliance is the physical device or server that

contains the data to be replicated. All mapping is done using the physical IP addresses of the
target and source StoreOnce Backup systems.

• In a multi-node StoreOnce Backup system, the appliance is the service set that contains the

data to be replicated. This means that each B6000 Backup system has at least two service
sets that can be selected as appliances. (A fully expanded HP B6000 Backup system would

40 Replication functions

have eight service sets.) All mapping is done using the virtual IP addresses of the target and
source service sets.

• In a single node StoreOnce VSA Backup system, the appliance is the virtual device or server

that contains the data to be replicated.

Within this section of the GUI the term appliance and service set are synonymous.

How do I identify the IP address of a service set?

When configuring replication to take place between multi-node and single-node StoreOnce Backup
systems, be aware that:

• For replication targets on an HP 26xx, 42xx or 44xx Backup system, you simply need the IP

address of the appliance.

• For replication targets on an HP VSA Backup system, there is only one service set similar to

a single node appliance. There are two virtual NICs supported, meaning you can have a
maximum of two IP addresses for the VSA.

See “Identifying IP addresses for the HP StoreOnce VSA Backup system” (page 41).

• For replication targets on an HP B6200 Backup system you need to identify the VIF address

of the appropriate service sets (also referred to as a node). Each HP B6200 StoreOnce Backup
system may have up to 8 service sets; the minimum is 2 service sets.

See “Identifying the VIF address for an HP B6200 Backup system” (page 42).

NOTE: Service set VIFs are used for data traffic and are not the same as the VIF that is used

to log onto the HP B6200 Management Console. You cannot configure the replication targets
using the VIF address that you use to log on to the HP B6200 Management Console.

Identifying IP addresses for the HP StoreOnce VSA Backup system

To identify the IP addresses from the Web Management Console/GUI home page

1. Navigate to the StoreOnce home page in the Web Management Console (GUI).

2. On the Status screen, look in the System Information box. You will see the two IP addresses
listed.

To identify the IP addresses using the StoreOnce CLI (command line interface)

Use the net show status all command.
This command will show the currently assigned IP addresses (static or via DHCP) to both of the

virtual NICs.

2. Locate its VIF IP in the System Information.

To identify the VIF address from the StoreOnce CLI (command line interface)

Use the net show config command and locate the Node Specific Parameters.
You are looking for the Network Virtual Data IP entries under each node. (The network

template that was applied at system installation determines whether it is a 10GbE or 1GbE network.)

• General Settings tab (page 50)

• Bandwidth Limiting tab (page 51)

• Blackout Windows tab (page 53)

General settings tab

Users with an Admin login may edit and maintain these settings. Other users may only view them.

1. Select the General Settings tab.

2. Click Edit to make the fields editable, see table below.

3. Click Apply to apply the settings.

Table 14 General Settings (Replication)

This shows the name of the appliance and its current status. It also tells you the product class
and the appliance supported protocol versions. The appliance supported protocol versions

Appliance

shows which versions of replication protocol are supported so incompatible versions will be
visible to the user. Replication auto negotiates to the lowest supported protocol on either
end.
You can only edit the appliance name. The default name is the network host name of the
appliance (as configured at installation). You may change this to something that is more
user friendly and will make it easier to identify the appliance on the Management Console
of the local and partner appliances. It may be anything that is meaningful to the user, such
as the geographical location of the appliance.

This is the maximum number of source and target jobs that can run concurrently. If necessary,
you can reduce the default value on this page. You may want to decrease the maximum

Maximum Jobs

source jobs to avoid using too much WAN bandwidth. You may want to reduce the maximum
number of target jobs to avoid overloading the target appliance and reserve appliance
performance, if you are running backups at the same time as replication.

An event is always generated each time a mapping goes out of sync and goes back into
sync. This field applies to periodic sync progress updates whilst the mapping remains out

logging interval. While the library or share is out of sync emails are sent periodically
indicating how many slots or entries are still out of sync. This information is also logged to
the user Event Log. One email is sent for each log entry made for each library or share that
is out of sync.

Use these fields to specify the amount of time a mapping needs to be out of sync before a
sync issue is shown in the Issue tab, and an event is generated, resulting in an entry in the

user Event Log, and also an email and/or an SNMP trap if the appliance is configured to
send these. These notifications are in addition to a standard notification email sent whenever
a mapping first becomes unsynchronized and another when synchronization is achieved.

Replication ports should only be changed if replication is blocked by a router on the WAN.
They must be the same on both source and target appliances. If in doubt, do NOT change
them.

Configure Replication
Ports

IMPORTANT: If replication needs to take place through a firewall, the network administrator will

need to open (TCP) ports 9387 (Command protocol) and 9388 (Data protocol) to allow the
replication traffic to pass to and from the HP StoreOnce Backup systems.

Bandwidth Limiting tab

This tab allows users with an Admin login to apply a general bandwidth setting and to configure
bandwidth limiting windows.

Bandwidth limiting can be used to avoid saturating the WAN with low bandwidth replication, thus
freeing up bandwidth for other processes and applications that you may have running. A minimum
of 2Mbps per concurrent job is recommended. At least 512kbps per concurrent job is required
for reliable operation. These limits apply to all outbound replication jobs from this local appliance.

Local Settings (Replication) tab 51

1. Display the Bandwidth Limiting tab.

2. Check the General Limiting Enabled box. You can now work out the recommended general

bandwidth limit, which is a simple calculation of:
(Max WAN Speed) x (Max Desired WAN Usage%).
A Bandwidth Limit Calculator is provided on this tab to work out limit values, if required.

3. Click Edit to edit the Bandwidth Limiting Windows.
You can configure two windows for each day. Use the spinners to select the Start of and End

of Restriction times. Enter the appropriate Bandwidth Limit in each required window. (If you
have used the Bandwidth Limit Calculator, enter the value from the Recommended Limit field.)

Be sure to check the appropriate Apply First/Second Restriction checkbox(es). This ensures
the times that have been specified are enabled. If it is not checked, the times are ignored.

52 Replication functions

NOTE: All settings are applied to the HP StoreOnce Backup system — you cannot configure

settings for individual jobs. The Bandwidth Limit windows override the General Limit when the
time specified for the window is active. Outside of Bandwidth Limit windows the General Limit
applies.

4. Click Apply.

Blackout windows tab

This option allows users with an Admin login to specify times when replication should not occur,
for example during planned maintenance or heavy network traffic. You may configure multiple
blackout windows.

NOTE: This setting relates to the local appliance in its role as a source or target device. No

replication jobs will be started if the Source or Target Appliance for a mapping is in blackout, and
any running jobs for the mapping will be paused.

1. Select the Blackout Windows tab.

2. Click Edit.

3. Check the box next to the required day of the week.

4. The time boxes become editable. Use the spinner menus to select the appropriate hours.

5. Set up as many blackout windows, as required.

6. Make sure the Apply First Time Restriction box is checked. This ensures the times that have
been specified are enabled. If it is not checked, the times are ignored.

7. If you want to enable a second blackout window, make sure the Apply Second Time Restriction
box is checked. The second blackout window for each day must occur after the first blackout
window for that day.

8. Click Apply. If you now look at the Appliance tab, you will notice that the calendar for the
Source and Target Appliances reflects the changes you have made.

VT Mappings (Replication)

VT Mappings page

This page displays details of all replication mappings between source and target libraries. Admin
users may use the two wizards on this page to configure replication mappings and recover mappings
after a disaster. (NAS share mappings are managed on a separate page.)

Use this page to:

• View source and target library mappings (all users), see Source and target library

mappings (page 55).

Admin users may also remove slot mappings and edit slot mappings.

• Run the Replication Wizard to create new mappings (Admin users only), see Running the

replication wizard (virtual tape devices) (page 57)

• Run the Recovery Wizard to restore mappings (Admin users only), see Recovering a source

appliance, VTL devices (page 61)

NOTE: You can only map and replicate deduplicating libraries and you can only map libraries

of the same version. You must be an administrator to manage mappings.

The below example shows the page layout when mappings have been created and a Replication
Source or a Replication Target library is selected. If a Non-Replicating Library is selected, no
mappings have been configured and the screen displays the Replication and Recovery Wizards.

Source and target library mappings

The top part of the VT Mappings page contains a list of all available local libraries. Local Libraries
are the libraries that have been configured on this HP StoreOnce Backup system.

• Non Replicating library: a library on this HP StoreOnce Backup system whose slots have not

yet been mapped for replication. Replication and Recovery Wizards are available only with
non-replicating libraries.

• Replication Source library: a library on this HP StoreOnce Backup system with cartridges that

have been mapped for replication. You do not have to map all cartridges in a
Replication-Source Library and the Replication-Target Library does not have to contain the
same number of cartridges as the Replication-Source Library.

• Replication Target library: a library on this HP StoreOnce Backup system with slots that hold

cartridges replicated from a Replication-Source library. The option is available to recover
individual cartridges from Replication-Target libraries.

NOTE: When you select a Non-Replicating library, you will be able to run the Replication or

Recovering wizard.

• Use the Replication wizard to create slot mappings for the non-replicating library; it becomes

a Source library. See Running the replication wizard (virtual tape devices) (page 57) for more
information.

• Use the Recovery wizard to recover cartridges from a Target Library. See Recovering a source

Mapping details tab

This tab details mapping details between source and target libraries. If a source library has been
selected, it will tell you whether Recovery is in process; if a target library has been selected, it will
tell you whether the target library is visible to the host. All other information is identical for both
source and target libraries. For example, use this tab to find out:

• The number of mapped slots and replication status

• The average throughput of data

Users with an Admin login may edit the Mapping Name on this tab.

Slot details

This tab displays details for each mapped slot in the selected slot mapping. It includes average
throughput data for each slot. If you have selected a source library, users with an Admin login will
be able to:

• Edit the Target Slot to which a Source Slot is mapped.

• Enable the Recover First checkbox, which enables a user to request that a mapped slot be

recovered from Target to Source, if required.

Running the replication wizard (virtual tape devices)

When you select a Non-Replicating library, you will be able to run the Replication or Recovery
wizard.

The Replication Wizard is used to create new mappings between Non-Replicating Libraries (which
become Replication Source Libraries) and either existing or new Target Libraries.

1. Create a Non-Replicating Library on the Source Appliance.

2. Create a backup rotation scheme and allow the first full backup to run.

3. Decide how you will seed the first full backup on the Target Appliance. Are you seeding across
the WAN or have you been able to colocate the Target Appliance on the same LAN as the
Source Appliance? See the HP StoreOnce Backup system Best Practices Configuration Guide
for a more detailed discussion about seeding.

4. Go to the Replication-VT Mappings page and select a Non-Replicating Library to be converted
to a Replication Source Library.

5. Click Start Replication Wizard and proceed to the Select Target Appliance step.

TIP: Click on the show/hide details link to check how many target appliances are permitted

and the number of target appliances that are currently configured.

VT Mappings (Replication) 57

6. Select a Target Appliance from the list and click Next.

NOTE: If you want to select an appliance that is not yet on the list, click Add Target Appliance.

Enter the Target Appliance IP Address or fully qualified domain name. The default values for
the Command and Data Protocol Port Numbers cannot be edited. (If replication needs to take
place through a firewall, the network administrator will need to open (TCP) ports 9387
(Command protocol) and 9388 (Data protocol) to allow the replication traffic to pass to and
from the HP StoreOnce Backup systems.) Click Add Target Appliance.

See also How do I identify the IP address of a service set? (page 41).

7. The wizard then moves to the Select Target Library step. Select a library on the target appliance

and click Next.

58 Replication functions

NOTE: If you need to create a new library on the target appliance, click Create New Target

Library. Set up the details as you would normally do when creating a new library device.

When creating libraries on a target device it is possible to create libraries with 0 (zero) drives.
Attempting to create a library with more drives than those available on the target will fail with
a suggestion that there may be too many drives already in use on the target.

You cannot create a new target library if Source Appliance Permissions is enabled on the
selected target appliance. Instead the library must be first created on the target before mapping
from the source.

8. This takes you to the Edit Slot Mapping step. Enter a Slot Mapping Name. The slot number
and barcodes of all source cartridges are displayed. A new barcode is generated for them

VT Mappings (Replication) 59

on the target library (these barcodes will be overwritten with those of the source when
replication starts). By default, all slots on the Source are selected for mapping and mapped
to available slots on the Target library. If you want to deselect cartridges from this slot mapping
configuration, select Unmapped from the Target Slot Name drop-down menu.

9. Click Next to display a summary of the replication configuration that you have created.

60 Replication functions

10. Click Apply to create the slot mapping configuration. Click OK at the Wizard Complete
prompt.

Replication of cartridges will start as soon as the libraries have been synchronised. Look at
the Replication Status field on the Library Details section of the VT Mappings page. It changes
from “Pending Synchronization” to “Synchronizing” to “Synchronized”.

NOTE: If you were able to co-locate the Target Appliance on the same LAN as the Source

Appliance to improve replication performance, remember to relocate the Target Appliance
to the target site as soon as the cartridges are synchronized.

Recovering a Source Appliance (Virtual Tape devices)

The Replication Recovery wizard allows Admin users to recover mapping configurations after a
disaster.

For example: the remote site has lost both the host servers and the StoreOnce system. New hardware
has been purchased and installed and the administrator now wants to recover data to the StoreOnce
Backup system and then restore to the host server. Before the failure a mapping existed between
a Source Library on the remote site StoreOnce Backup system and a Target Library on the Data
Center StoreOnce Backup system. After the failure the Source Library is missing; the mapping may
or may not still exist.

IMPORTANT: If you replace the disks in the source StoreOnce Backup system and keep the

original appliance, the source to target mapping will still exist on the repaired StoreOnce Backup
system. You MUST break this mapping BEFORE carrying out recovery. If you do not, the now blank
Source Library (on the replacement disks) will overwrite the data on the Target Library. You will
effectively lose backup data on both Source and Target Libraries.

1. Create a new Non-Replicating Library on the Source Appliance (either by running the Installation
wizard or by using the Devices page).

2. Go to the Replication - VT Mappings page and select the new non-replicating library.

3. Click Start Recovery Wizard.

62 Replication functions

4. At the Select Target Appliance Step, select Add the Target Appliance and provide the IP

address of the previous replication target device.

5. Select the existing Target Library, or the Non-Replicating Library that was the Target Library
before mapping was broken, from which slots should be recovered.

TIP: Use the Click to show/hide details box to view further information about configured

and maximum shares, libraries and mappings.

VT Mappings (Replication) 63

6. If it is an existing Target Library, you may select the Slot Mapping that had been configured

and click Next. If the mapping had been broken and the library has reverted to
Non-Replicating, you can also add a new slot mapping.

If the Target Library supports multiple library Fan In, the library may still be a Replication
Target if other mappings exist. You can now recover by adding the mapping back to map
the unmapped slots to the new Source Library.

7. All slots in the Target Library will be selected by default, but you may deselect any cartridges
that you do not wish to recover to the Source Library.

64 Replication functions

8. Click Next to display the Summary page.

9. Click Apply to run reverse replication.

10. As soon as reverse replication has completed for each slot, the data may be recovered to the
host using the original backup application.

11. New backups can now run to the Source Appliance and replication will run normally without
further configuration.

NAS Mappings (Replication)

This page displays details of all replication mappings between source and target shares. Admin
users may use the two wizards on this page to configure replication mappings and recover mappings
after a disaster. (VT library mappings are managed on a separate page.)

Use this page to:

• View source and target share mappings (all users), see Source and target share

details (page 67).

Admin users may also remove share mappings and edit share mappings.

• Run the Replication Wizard to create new share mappings (Admin users only), see Running

the replication wizard (NAS) (page 69)

• Run the Replication Recovery Wizard to recover share mappings Recovering a source appliance

(NAS shares) (page 73)

NOTE: You can only map and replicate deduplicating shares and you can only map shares of

the same version. You must be an administrator to manage mappings.

NOTE: The above example shows the page layout when mappings have been created and a

Replication Source or a Replication Target share is selected. If a Non-Replicating Share is selected,
no mappings have been configured and the screen displays the Replication and Recovery Wizards.

Source and target share details

The top half of the NAS Mappings page contains a list of all available NAS shares that have been
configured on this HP StoreOnce Backup system.

• Non Replicating: a share on this HP StoreOnce Backup system that has not yet been mapped

for replication. Replication and Recovering Wizards are available only with non-replicating
shares.

• Replication Source: a share on this HP StoreOnce Backup system that has been mapped for

replication.

• Replication Target: a share on this HP StoreOnce Backup system that has been replicated from

a Replication-Source share.

NOTE: When you select a Non-Replicating share, you will be able to run the Replication or

Recovery wizard.

• Use the Replication wizard to create slot mappings for the non-replicating share; it becomes

a Source share. See Running the replication wizard (NAS) (page 69) for more information.

• Use the Recovery wizard to recover files from a Target share. See Recovering a source

appliance (NAS shares) (page 73) for more information.

File details tab

This tab displays mapping details for each directory and files within it. It includes average throughput
data for each file. You cannot edit any details on this tab, but you can click on any of the column
headings to sort the file details according to that column.

Running the replication wizard (NAS)

The Replication Wizard is used to create new mappings between Non-Replicating NAS shares
(which become Replication Source shares) and either existing or new Target shares. (See Recovering

a source appliance (NAS shares) (page 73) for information about the Recovery wizard.)

1. Create a Non-Replicating Share on the Source Appliance.

2. Allow the first full backup to run.

3. Decide how you will see the first full backup on the Target Appliance. (See also the HP
StoreOnce Backup system Concept Guide).

• You can seed across the WAN.

• You can colocate the Target Appliance on the same LAN as the Source Appliance.

4. Go to the NAS Mappings page.

5. Select a Non-Replicating Share to be converted to a Replication Source Share and click Start
Replication Wizard.

6. Proceed to the Select Target Appliance step.

TIP: Click on the show/hide details link to check how many target appliances are permitted

and the number of target appliances that are currently configured.

NAS Mappings (Replication) 69

7. Select a Target Appliance from the list and click Next.

NOTE: If you want to select an appliance that is not yet on the list, click Add Target Appliance.

Enter the Target Appliance IP Address or fully qualified domain name. The default values for
the Command and Data Protocol Port Numbers may not be edited. (If replication needs to
take place through a firewall, the network administrator will need to open (TCP) ports 9387
(Command protocol) and 9388 (Data protocol) to allow the replication traffic to pass to and
from the HP StoreOnce Backup systems.) Click Add Target Appliance.

See also How do I identify the IP address of a service set? (page 41).

8. The wizard then moves to the Select Target Share step. Select a share on the target appliance

and click Next.

70 Replication functions

NOTE: If you need to create a new share on the target appliance, click Create New Target

Share. Set up the details as you would normally do when creating a new share. You cannot
create a new target share if the appliance to be used as the target has Replication Source
Permissions enabled.

When you create a new share, you are warned that it will take a few seconds for the new
share to come online. Click OK.

9. Give the Share Mapping a name and click Next.

NAS Mappings (Replication) 71

10. The Summary screen is displayed. Click Apply to create the share mapping configuration.

Replication of files will start immediately.

NOTE: If you were able to colocate the Target Appliance on the same LAN as the Source

Appliance to improve replication performance, remember to relocate the Target Appliance
to the target site as soon as the files are synchronized.

72 Replication functions

Recovering a Source Appliance (NAS shares)

There are two ways of recovering NAS shares mappings after a disaster.

• Reverse replication using the wizard (page 73)

• Promotion of Target share over the WAN (page 77)

IMPORTANT: If you replace the disks in the source StoreOnce Backup system and keep the

original appliance, the source to target mapping will still exist on the repaired StoreOnce Backup
system. You MUST break this mapping BEFORE carrying out recovery. If you do not, the now blank
Source Share (on the replacement disks) will overwrite the data on the Target Share. You will
effectively lose backup data on both Source and Target Shares.

Reverse replication using the wizard

In this example, the remote site has lost both the host servers and the StoreOnce Backup system.
New hardware has been purchased and installed and the administrator now wants to recover
data to the StoreOnce Backup system and then restore to the host server. Before the failure a
mapping existed between a Source Share on the remote site StoreOnce Backup system and a
Target Share on the Data Center StoreOnce Backup system. After the failure the Source Share is
missing; the mapping may or may not still exist.

1. Create a new Non-Replicating Share on the Source Appliance (by using the NAS Shares
page).

2. Reverse seed the first full restore. The simplest way to do this is to use a USB disk, as described
below. It is also possible to recover across the WAN, but this may place an unacceptable
load on bandwidth or time availability.

It is possible to reverse seed the first full restore using a USB disk, as follows:

• Map from the host at the target site to the NAS share on the HP StoreOnce Backup system

and copy the share to a USB disk attached to the host.

• Transport the media to the Replication Source site and attach it to a host.

• Map from a host at the source site to the new share on the Replication Source and copy

across the data from the USB disk before running the Recovery wizard.

NAS Mappings (Replication) 73

Figure 4 Recovery by reverse seeding NAS shares on a replacement source appliance

3. Go to the Replication - NAS Mappings: page and select the new non-replicating share.

4. Click Start Recovery Wizard.

5. At the Select Target Appliance step, select Add Target Appliance and provide the IP address

of the previous replication target device.

74 Replication functions

6. Select the existing Target. This is the Target NAS share from which files should be recovered.
Click Next.

NOTE: If the mapping has been broken there will be an entry that says Non-replicating

share (instead of Replication Target).

7. At the Edit Share Mapping step, either adopt the mapping that had been configured or create
a new mapping and click Next.

NAS Mappings (Replication) 75

8. Click Adopt to run reverse replication.

9. As soon as reverse replication has completed, the data may be recovered to the host using
the original backup application.

10. New backups can now run to the Source Appliance and replication will run normally without
further configuration.

Figure 5 Reverse replication process: source lost

Promoting a Target Share over the WAN using NAS

The remote site has lost both the host servers and the StoreOnce system. New server hardware
has been purchased and installed and the administrator now wants to recover data to the server.
The administrator has not installed a new StoreOnce Backup system and is going to recover data
directly to the server from the Data Center StoreOnce appliance over the WAN (which will take
a long time).

NOTE: The procedure described below retains the ability to back up to the Target Share. If this

is not required, a simpler solution may be to recover data from the Target Share, which is read-only.

NAS Mappings (Replication) 77

Figure 6 Recovery by promoting a Target Share over NAS

Before the failure a mapping existed between a Source Share on the remote site StoreOnce Backup
system and a Target Share on the Data Center StoreOnce Backup system. After the failure the
mapping still exists but the Source Share is missing. The Target Share on the Data Center StoreOnce
Backup system is still in Target Share mode, it has not had its mappings removed.

1. On the Target Appliance in the Data Center, go to the Replication - NAS Mappings page,
select the Target Share and remove the mapping between it and the lost Source Share.

2. The Target Share becomes a Non-Replicating Share.

3. Make sure the backup application is targeting the newly non-replicating share and recover
the data.

4. At this point there is no HP StoreOnce Source Appliance at the remote site. If one is installed
at a later date, you can reverse recover the data and configure replication, as described in

Reverse replication using the wizard (page 73).

6 HP StoreOnce Catalyst functions

The following StoreOnce Catalyst functions are available:

• Viewing and managing StoreOnce Catalyst settings, StoreOnce Catalyst (page 81)

• Viewing and managing Catalyst stores, Catalyst Stores (page 88)

For general information about StoreOnce Catalyst see What is HP StoreOnce Catalyst (page 80).

NOTE: With the current version of the software there are no equivalent CLI commands available

for the tasks described in this section.

IMPORTANT: If Catalyst operations need to take place through a firewall, the network administrator

will need to open (TCP) ports 9387 (Command protocol) and 9388 (Data protocol) to allow the
Catalyst traffic to pass to and from the HP StoreOnce Backup systems.

Licensing requirements

OST/Catalyst devices require a license to be used at both source and target – but do NOT require
an additional replication license as well.

OST 2.0 plug-in

For supported Symantec backup products, a plug-in application is required on each backup
application media server that will use the Catalyst functionality. This can be downloaded from the
Software Storage section of your StoreOnce product's Download drivers and software page on

http://www.hp.com/support/downloads.

What is HP StoreOnce Catalyst

HP StoreOnce Catalyst is a StoreOnce function that allows:

• Backup applications to back up data to a target store on the HP StoreOnce Backup system.

Deduplication may occur on the media server or on the HP StoreOnce Backup system.

• Backup applications to copy jobs between HP StoreOnce Backup systems. All configuration

is carried out from the backup application, which makes this an attractive alternative to using
the replication function on the HP StoreOnce Backup system.

This function requires a backup application that supports HP StoreOnce Catalyst. The HP OST 2.0
plugins should also be installed on any Media Servers that will be transferring data to the StoreOnce
Backup system. Refer to http://www.hp.com/go/ebs for up-to-date details on supported
applications.

IMPORTANT: Much of the information that is displayed on the HP StoreOnce Catalyst pages is

taken directly from the backup application. It is strongly recommended to give jobs and media
server groupings names on the backup application that will also be meaningful when they are
displayed in the StoreOnce Catalyst pages.

Benefits of HP StoreOnce Catalyst

• The backup application is in full control of its data for the full lifecycle of the backup data

• The backup application has full visibility of all items and jobs on the HP StoreOnce Backup

system

• Deduplication can occur on either the media server or HP StoreOnce Backup system, which

ensures efficient use of the available bandwidth

• There is no limiting geometry, such as cartridges for VTL libraries

80 HP StoreOnce Catalyst functions

• There is no enforced limit on the number of items within a store

• Copy jobs are instigated from the application and have none of the complexities of replication

mapping

StoreOnce Catalyst terminology

• StoreOnce Catalyst: the name of the StoreOnce function

• StoreOnce Catalyst stores: the targets/device types in which backups are stored on the HP

StoreOnce Backup system

• StoreOnce Catalyst items: the items stored in the StoreOnce Catalyst stores on the HP StoreOnce

Backup system

• StoreOnce Catalyst clients: the generic term for applications that connect using the StoreOnce

Catalyst interface

• Data jobs: any backup or restore job

• StoreOnce Catalyst Optimized Backups: one of the main advantages of HP StoreOnce Catalyst

is that deduplication may occur on either the media server or the HP StoreOnce Backup system.
If deduplication occurs on the media server so that only unique data is sent to the HP StoreOnce
Backup system, a low bandwidth network link is adequate. If the media server sends all the
data and deduplication is carried out on the HP StoreOnce Backup system, a high bandwidth
network link is required. The combined CPU power of multiple media servers and the reduced
network traffic means that it is often faster to deduplicate on the media server. However, actual
performance varies depending upon the data and disk I/O speeds.

• Copy jobs: these allow backup applications to create true copies of the data and not mirror

images. The backup application specifies the store on the source StoreOnce Backup system
for the outbound copy job and a target store on the destination StoreOnce Backup system for
the inbound copy job. Once copied, the two versions are independent of each other; on either
the source or destination StoreOnce Backup system data may subsequently be deleted, moved
or added to, as required, from the backup application.

• StoreOnce Catalyst Optimized Copy: all copy jobs are optimized. This means that the copy

job is completed in a bandwidth-efficient manner. The two stores negotiate so that only unique
data is transferred.

StoreOnce Catalyst page

This page has a number of tabs that provide access to the following StoreOnce Catalyst functions:

• StoreOnce Catalyst status tab (page 82)

• StoreOnce Catalyst settings tab (page 83)

• StoreOnce Catalyst clients tab (page 84)

• StoreOnce Catalyst blackout windows tab (page 86)

• StoreOnce Catalyst bandwidth limiting windows tab (page 87)

Select StoreOnce Catalyst from the Navigator to display the StoreOnce Catalyst page and associated
tabs.

StoreOnce Catalyst terminology 81

NOTE: Click on + to expand the StoreOnce Catalyst topic in the Navigator and access the

Catalyst Stores topic.

StoreOnce Catalyst Status tab

The Status tab displays details about

• StoreOnce Catalyst status and protocol

• StoreOnce Catalyst copy and data job throughput totals

• Active Sessions

Details refresh every 10 seconds, so this information provides a useful overview of Catalyst activity
on the StoreOnce Backup system. However, the data displayed on this status page is generally
for information purposes only. The customer is not advised to try to make inferences based on the
values shown.

deduplication). These are aggregate numbers. The throughput numbers should correlate with
those shown on the graphs on the Activity page.

The right-hand column shows the number of jobs of each type that are running.Active Sessions

NOTE: Different backup applications can use different terminology for data transfers. From

a Catalyst perspective, if data is being moved between the HP StoreOnce Backup system and
a media or application server, this is a data job. If the transfer is between two HP StoreOnce
Backup systems, this is a Catalyst Copy job. For Copy jobs the HP StoreOnce Backup system
is responsible for all data movement (although the process is initiated by the backup application
software). For data jobs the backup application is responsible for the data movement.

• Data Jobs running shows how many active Catalyst backup connections (for read or write)

are currently active.
The HP StoreOnce Backup system has the following data connections available, which are

shared across all interfaces (VTL, NAS and Catalyst) and include any being used for inbound
replication or inbound Catalyst Copies.

HP StoreOnce VSA: 16

• Outbound copy jobs use a separate set of streams. The maximum is:

HP StoreOnce VSA: 4

• Inbound copy jobs share the same pool as Data Jobs.

• Client command connections are limited as follows, this number should never stay near the

maximum level for any period of time.
StoreOnce VSA: 8

If the copy job numbers are high (close to the maximum), no user action is required. Copy
activities happen under the control of the StoreOnce Backup system and it will optimize the
queuing and running of jobs based on the resources available. If the Data job count starts
getting high, the HP StoreOnce Backup system is being loaded quite heavily. You may see
jobs failing to start or running slowly (although the aggregate performance across the many
jobs should still be high) due to insufficient resources being available.

NOTE: The maximum data jobs value is not guaranteed in all cases. In some situations, such

as when heavily loaded, the actual maximum may be less (based on resources available to
the box at that time).

StoreOnce Catalyst Settings tab

The StoreOnce Catalyst Settings tab is used to view the settings that apply to Catalyst functions
and jobs for all nodes on the HP StoreOnce Backup system. Users with an Admin login may also
edit these settings.

IMPORTANT: You must first enable Client Access Permission Checking on this page, if you wish

to assign permissions when you subsequently configure clients and stores. (If you do not set
permissions, all clients will be able to access all stores.)

bandwidth.

This is the maximum number of data and inbound copy jobs that can be

system to identify a client. For example, there may be multiple media servers
sharing the same ID; so, the identifier is not a client machine name or a name
generated by the software. Best practice is to ensure that the name created on
the backup application is meaningful for use in searches on the StoreOnce
Backup system.

This is a description that can be included on the StoreOnce Backup system

StoreOnce Catalyst Blackout Windows tab

The two fields at the top of this tab show the System Time and whether a Blackout Window is
currently active. The information below displays the start and stop times of any blackout windows
that have been configured for outbound copy jobs.

Users with an Admin login may specify times when outbound copy jobs should not occur, for
example during planned maintenance or heavy network traffic. Multiple blackout windows may
be configured.

NOTE: Blackout windows are available on most StoreOnce functions, so that you can ensure

that all StoreOnce services run efficiently and do not compete for resources. For example, if you
are running backup, restore, replication and Catalyst Store operations with no break (i.e. 24 hours
a day), housekeeping will never be able to complete and performance will suffer. This is a complex
subject, see also Best Practices for VTL, NAS, StoreOnce Catalyst and Replication implementations:.

To edit StoreOnce Catalyst blackout windows (administrators only)

1. Select the Blackout Windows tab.

2. Click Edit.

3. Check the box next to the required day of the week.

4. The time boxes become editable. Use the spinner menus to select the appropriate hours.

5. Set up as many blackout windows, as required.

6. Make sure the Apply First Time Restriction box is checked. This ensures the times that have

StoreOnce Catalyst Bandwidth Limiting Windows tab

There are four sections to this tab, all of which relate to bandwidth limiting on outbound copy jobs.

• Status: which details the current bandwidth limit, if any

• General bandwidth limit: where administrator users may enable and apply a general bandwidth

limit. This is a simple calculation of:
(Max WAN Speed) x (Max Desired WAN Usage%).

• Bandwidth limit calculator: which is provided on this page to help work out limit values for

the general bandwidth limit and the bandwidth limiting windows, if required.

• Bandwidth limiting windows: where administrator users may specify times certain times when

different bandwidth limits may apply. Any bandwidth limit entered here will overwrite the
general bandwidth limit.

Bandwidth limiting can be used to avoid saturating the WAN, thus freeing up bandwidth for other
processes and applications that you may have running. A minimum of 2Mbps per concurrent job
is recommended. At least 512kbps per concurrent job is required for reliable operation. These
limits apply to all outbound copy jobs from this local appliance.

To edit bandwidth limiting (administrators only)

1. Display the Bandwidth Limiting Windows tab.

2. Check the General Limiting Enabled box. You can now work out the recommended general
bandwidth limit, which is a simple calculation of:

(Max WAN Speed) x (Max Desired WAN Usage%).
Use the bandwidth limit calculator provided on this page to work out limit values, if required.

3. Click Edit to edit the Bandwidth Limiting Windows.
You can configure two windows for each day.
Be sure to check the appropriate Apply First/Second Restriction checkbox(es). This ensures

the times that have been specified are enabled. If it is not checked, the times are ignored.
Then enter the required Bandwidth Limit in each required window manually.

Use the bandwidth limit calculator provided on this page to work out limit values, if required.

NOTE: All settings are applied to the HP StoreOnce Backup system — you cannot configure

settings for individual jobs. The Bandwidth Limit windows override the General Limit when the
time specified for the window is active. Outside of Bandwidth Limit windows the General Limit
applies.

policies have different values, the media server will determine which is the most bandwidth
efficient transfer policy to use.

This may be High or Low (see definitions in row above) and is normally the opposite to the
Primary transfer policy so that the media server can choose to use which is most appropriate.

Secondary transfer
policy

However, if you wish to enforce the transfer policy that the media server uses, set both Primary
and Secondary transfer policies to the same value.

and click Update.

Item summary tab

This tab provides summary details of each item in the store.

• Use the filter options to locate the required item(s).

• By default 50 items are displayed per page. This may be changed from Items per Page. Either

use the scroll bar to scroll through all items on the page; or use the Prev or Next buttons to
display more pages.

• Once items are displayed, users with an Admin logon may use the Delete button to delete a

selected item.

• All users may use the buttons under the item details to show Related data jobs, Outbound copy

jobs orinbound copy jobs for the selected item.

NOTE: This tab provides a report; it is not automatically refreshed.

1. If necessary click + to display the filter options.

Item Name

The status of the data job item, which may be:Status

• Running: in progress

• Completed: the item has completed successfully, this does not mean the data job has

completed, only the item, and does not reconcile with the backup application job
completion status

• Cancelled: the Status Information provides more details, for example, the data

connection has been lost between the HP StoreOnce Backup system and the media
server (this is unlikely to occur)

• Unexpected error: the StoreOnce Backup system has experienced a problem whole

processing the item

• Insufficient disk space: it will be necessary to clear some disk space or add more storage

• Link failure: IP connectivity has been lost and the backup application must retry the job

• System shutdown

NOTE: The backup application must be configured to tidy up any incomplete or orphaned

items before retrying the job.

The amount of user data that was written. This reconciles with the information in the backup

deduplication with a low-bandwidth transfer policy, or target-side deduplication with a
high-bandwidth transfer policy. See Store Details tab (page 89).

The read throughput speed. This only has one value because read throughput is always
high throughput without any % saving.

System information messages

A job may have been cancelled for the following reasons that will be shown in the Status
Information:

• Cancelled By User. This means that the customer cancelled the copy job either through the

backup application or via the Management Console GUI.

• Unexpected Error, something bad has happened but we do not know what. Contact HP

Support.

• Lock Release Request, the destination Catalyst item was opened by another process. This is

unlikely to be seen by customers as their backup application should prevent this from occurring.

• Out of Space, the customer has run out of disk space. The customer should take one of the

following actions:

1. Expire backups that are no longer required and wait for housekeeping to free up space.

2. Purchase additional storage.

3. Perform the copy to a different store that has available free capacity.

• Not Licensed, the destination store does not have a license in place to accept copies for this

backup application. The customer should check the licenses installed. The copy job will need
to be resubmitted once the license is applied.

• Permission Denied, the client requesting the copy no longer has permission to access the

destination store. The customer should check access permissions on the destination appliance
and then resubmit the copy job.

• ObjectStore Not Present, the destination store is no longer available. The customer should

check the destination appliance and ensure the store exists. Customers are very unlikely to
see this failure unless they delete a store whilst they have copies queued.

• ObjectStore Origin Same As Destination; customers are unlikely to see this message as backup

application should not allow you to copy backups within a store.

• Object Not Present, customers are unlikely to see this message as backup application should

not allow you to copy backups within a store.

• Object Storage Mode Mismatch, customer will not see this error message yet because we only

support one type of storage mode.

• Server Incorrect Address Or Protocol, customers are very unlikely to see this error message as

the backup application should validate their input. If they do encounter it they should probably
check their backup application configuration.

• Object Extent or Offset Invalid.This error message means that the backup application tried to

copy a backup incorrectly. They should check their backup application setup, although it’s
very unlikely a customer would see this error message.

Catalyst Stores page 99

• Object Changed Whilst Queued or Paused. If a customer sees this error message they should

check the backup policy as their backup application is making changes to Catalyst items when
they shouldn’t. The customer will need to try the copy again within the backup application.

• Object Not Ready. This shouldn’t happen but if it does, the customer should contact HP Support.

• Job State Inconsistency Found. This shouldn’t happen but if it does, the customer should contact

HP Support.

A job may have been paused for the following reasons:

• Link failure, the network between the appliances is down. The customer should check the

network connectivity. Once the connection is re-established the copy should automatically
continue.

• Shutdown, the source or destination appliance was shutdown. Once the appliance is back

online the copy should automatically continue.

• Blackout window, a blackout window is in effect on the source appliance. Once the blackout

window expires, the copy should automatically continue.

• Server Too Busy, the source or destination appliance is too busy to run the copy job. The copy

job will automatically be restarted when resources are available.

• System shutdown

To cancel a copy job

It is recommended to cancel copy jobs via the backup application and only use the GUI as a last
resort. This ensures that the backup application catalog stays in sync with the backup images.

1. Select the job to be cancelled in the outbound copy job list.

2. Click Cancel Job.

3. At the confirmation prompt click OK.

Inbound copy jobs tab

This tab provides a log with details about inbound copy jobs for the selected store.

• Use the filter options to locate the required job(s).
