1 Getting started
The following topics are covered in this chapter:
• This guide (page 7)
• Overview of HP StoreOnce Backup products (page 7)
• User types and user roles (page 7)
• Navigating the StoreOnce Graphical User Interface (GUI) (page 9)
• Navigating the online help (page 10)
• The StoreOnce CLI (page 12)
• Licensing (page 12)
This guide
This guide contains detailed information on using the StoreOnce GUI and includes some Command
Line Interface commands and troubleshooting information.
• Tasks available only in the StoreOnce GUI are described only in this guide.
• Tasks available in both the GUI and CLI are described in this guide. (The CLI command is
described in greater detail in the HP StoreOnce Backup system CLI Reference Guide.)
• Tasks only available in the CLI are described fully in the HP StoreOnce Backup system CLI
Reference Guide. Those tasks may not be described in this guide.
Overview of The HP StoreOnce Backup system
The HP StoreOnce VSA extends the StoreOnce portfolio with the agility and flexibility of StoreOnce
as a virtual appliance. Install into an existing vSphere (v5.x) environment without the need for
dedicated hardware. 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.
StoreOnce VSA can be deployed using either SEM or via a vSphere client specific hardware. The
StoreOnce VSA is available to purchase by license, which includes HP StoreOnce Catalyst and
Replication support.
The StoreOnce VSA model, TC458A and D4T77A:
• Description: A virtual machine with ten 1TB disks
• Ports: 2 x 1GBE ports
• Storage expansion: Up to ten virtual disks of 1TB
• Interfaces supported: iSCSI only
User types and user roles
User roles
Two roles define the permissions associated with a user; admin and user. Two default user accounts,
one for each role, are created automatically when the system is installed:
• Administrator: Authorized users can create and edit management and StoreOnce functions
via the GUI and CLI. The default login and password are Admin and admin. The permissions
role of the Administrator is admin. You cannot delete this account, but you can and should
modify its password. Note that once the Admin account password has been changed, its
password cannot be changed back to admin as this password is not sufficiently complex. The
This guide 7
only way to revert that password back to admin is via the HPresetpassword account which is
only available on the local console of the device.
• Operator: This account limits access to the GUI and CLI to monitoring and viewing. The default
login and password are Operator and operator. The permissions role of the Operator is user.
User types
After installation, an Administrator can configure additional user accounts and assign permissions
roles (admin or user) and passwords to these users. See the HP StoreOnce Backup system user
guide.
There are three types of user accounts:
• Local User (with an administrator or user permissions role): Local users log in locally.
• External User (with an administrator or user permissions role): User logs in as a domain user.
An external user is a Microsoft Active Directory user.
• External Group (with an administrator or user permissions role): An external user is a Microsoft
Active Directory group. Members of the group log in as domain users. If after creating a group
you then set up a member of that group as an individual user (external user) and give them
an administrator role, that user will be an administrator, even if the group role is set to user.
This is because role permissions set through Add User take precedence over role permissions
set through Add Group.
Any user with an admin role has the same permissions as the default Administrator. Any user with
a user role will have the same permissions as the default Operator.
NOTE: To add external users or groups, first add the StoreOnce device to an AD domain.
Connection to an AD Domain is configured through the NAS CIFS server tab on the StoreOnce
GUI. See Configuring CIFS Server with AD and CIFS Share with AD domain users (page 34).
IMPORTANT: If Admin credentials are lost, the Admin password can be reset through the account
“HPresetpassword”. This account is password protected and is only accessible from the StoreOnce
console and CLI. HP recommends the end-user change the HPresetpassword password after
installation and store it in an offline Password Security tool.
Tip
To identify current user rights view the title bar of the GUI. This shows your user Type, Name, and
Role. See (page 10).
Powering off and on
HP recommends using the CLI commands to power off and on the system instead of using the
“power off” and “power on” controls on the hypervisor. See the HP StoreOnce VSA Deployoment
and Configuration guide for more information.
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) or Hyper-V
Manager installed by the customer. Once deployed, the customer has access to web management
via the StoreOnce GUI or command line management via the CLI. The StoreOnce VSA Backup
System supports 10 x 1 TB virtual disks.
8 Getting started
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 Hyper-V Manager
• 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 Graphical User Interface (GUI)
The HP StoreOnce GUI and CLI together make up the Management Console. While there is overlap
in what operations you can perform, not all operations are available from both interfaces.
The HP StoreOnce GUI 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 GUI
Log on to the StoreOnce GUI using a browser on any machine connected to the management
network; see “User types and user roles” (page 7) for default login information. The HP StoreOnce
Backup system uses a secure network connection.
Enter: https://<IP_address> .
NOTE: Entering http: in the URL path will automatically forward to the https: secure network
connection.
The StoreOnce GUI displays the Login prompt.
NOTE: The web browser requires Active Scripting or JavaScript enabled. If both are disabled,
some browser buttons may not be displayed.
Navigating the HP StoreOnce Graphical User Interface (GUI) 9
GUI components
The GUI includes:
• Title bar: Displays the HP StoreOnce Backup system model, the user name and role, and
contains the Logout and Help buttons.
NOTE: After 15 minutes of inactivity, the session times out and returns to the Login screen.
• System Status (top left side panel): Displays the last time the system was updated (the machine
time) and a count of event status categories.
The three icons described below are used in the System Status area. They do not identify the
event that has affected the status. To view the individual events for more detail, select Events
from the Navigator, as described in Events (page 124).
Indicates standard information.
Indicates a warning state. Attention is needed but the error is not critical to the successful operation of
the device. For example, a single disk failure occurs or disks are installed in an expansion shelf but
not licensed.
Indicates a critical state. The system requires immediate attention. This icon may also appear in the
Details area of the screen with a red square background (rather than a red circle).
• Navigator (left side panel): Displays available GUI topics and enables navigation to selected
topic pages. A + sign next to a topic indicates additional options; click + to expand the
selection and click — to contract the selection.
• Topic page (main window): Initially, the main window displays the top-level StoreOnce topic
page. Select another topic from the Navigator to display the page for that selection. Some
Topic pages require selection of an item, such as a library, NAS share, or Catalyst store in
the top half of the page to display details specific to the selected item in the lower half of
page. Some Topic pages include multiple tabs within the page, for example the VTL—Libraries
page. Select a tab to display information and actions appropriate to that tab.
Navigating the online help
The Help link in the top right-hand corner of each page displays context-sensitive information for
the current page.
10 Getting started
The following example displays the Help when selected from the NAS Mappings page.
• Click and drag on a side or a corner to expand or contract the Help window.
• The header displays the page where the help was called. Links navigate to the next or previous
pages; the titles of the next and previous pages are beneath the respective links.
• The footer also provides navigation options. Select home to access the help Home page which
provides access to the complete online help and Contents, Search, and Index options. Resize
the page to view all of the content.
Navigating the online help 11
The StoreOnce CLI
The StoreOnce Command Line Interface (CLI) provides an alternative way of administering and
monitoring the system. Some tasks are only accessible 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 as described in Accessing the CLI (page 126).
See the HP StoreOnce Backup system CLI Reference Guide for more information about the StoreOnce
CLI commands.
Licensing
HP StoreOnce VSA has a single license that enables StoreOnce Catalyst and Replication. The
license also includes the security features of Data at Rest Encryption, Data in Flight Encryption, and
Secure Erase.
Security Features
The security features of Data at Rest Encryption, Data in Flight Encryption, and Secure Erase are
part of the VSA license.
NOTE: StoreOnce replication can be encrypted at the Network layer. This feature is included in
the Security license. See the HP StoreOnce Backup system CLI Reference Guide for more details;
review the networking configuration commands such as net add encryption.
Data at Rest Encryption
When enabled, the Data at Rest Encryption security feature protects data at rest on a stolen,
discarded, or replaced disk from forensic attack.
Creation of a new VTL library, Catalyst store, or NAS share provides the option to enable encryption
if the license was already applied. Once enabled, encryption will automatically be performed on
the data before it is written to disk. Encryption cannot be disabled once it is configured for a library,
Catalyst store, or NAS share.
When creating an encrypted library, Catalyst store, or NAS share, the key store is updated with
the encryption key. This key store may be backed up and saved securely offsite in case the original
key store is corrupted. However, keep only the latest version of the key store as a backup. The key
store on the StoreOnce Backup system is updated each time you create a library, Catalyst store,
or NAS share. The StoreOnce CLI command that backs up the key store also encrypts it, ensuring
it can only be decrypted by the HP StoreOnce backup system.
NOTE: Each configured library, Catalyst store, or NAS share uses a different key. The StoreOnce
software automatically tracks which key is relevant to which device in the Key Store File. Keys are
automatically re-applied to the correct device if the key store file is restored.
IMPORTANT: Be very diligent about backing up your keystore if you are creating encrypted
stores or libraries. See the HP StoreOnce Backup system CLI Reference Guide for more information
about the StoreOnce CLI commands for backing up and restoring key stores.
Data in Flight Encryption
When enabled, the Data in Flight Encryption security feature protects data that is in transit from
forensic attack using the IPsec protocol. The data can be moving between two StoreOnce Backup
appliances or a StoreOnce Backup appliance and a backup server.
Data in Flight Encryption is configured using the net [add/modify/delete] encryption
commands in the CLI; see the HP StoreOnce Backup system CLI Reference Guide for more
information.
12 Getting started
Secure Erase
Secure Erase can be enabled for all store types. This feature enables allows secure erasure of data
that was backed up as part of a regular backup job. The Secure Erase feature can only be enabled
after store or library creation (edit the store or library to enable Secure Erase). All data written to
disk once Secure Erase is enabled will be securely erased upon data deletion. For example, you
may have unintentionally backed up confidential data and need to be sure that it has been securely
erased. Work with the backup application to trigger the Secure Erase, for example by forcing the
format of a cartridge. The backup application sends the request to delete the data and the deletion
is carried out as part of the Housekeeping function.
WARNING! To immediately remove data, ensure the backup application is configured correctly.
Rotation and retention policies may need to be revisited to ensure that the data is expired.
NOTE: The Secure Erase process may take some time depending on the Housekeeping workload.
Only chunks not referenced by any other items can be securely erased. If a chunk is referenced
by another item which is not marked for Secure Erase, then the referenced chunk will not be erased,
securely or otherwise. Use the backup application when performing a Secure Erase on stores,
shares, or libraries that have Secure Erase enabled.

The name used to identify a particular library. Enter a name that identifies the host or backup
job with which it is associated.
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 21). The emulation type
determines the available embedded drives and cartridge slots. For example, if you select
HP MSL G3 Series (2x24), the device emulates 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 information about device types they support.
The drive emulation type, HP LTO–2, 3, 4, 5 or 6, determines the default capacity of the
cartridges within the library device and the iSCSI inquiry string information provided to the
backup application. Tape cartridge capacities can be increased at any time (but not
decreased), as long as the cartridge is blank, regardless of the drive emulation generation
number.
If you selected D2DBS Generic for the Library Emulation Type, Ultrium VT is an option for
drive emulation. This is a generic Ultrium device which is clearly identifiable as virtual.
Where supported by the backup application, HP recommends that D2DBS Generic and
Ultrium VT are used in preference to the other emulation types.
All drives on a library configured with the IBM-TS3500 emulation type will use the IBM-LTO3
drive emulation type. If the library is then changed to a different emulation type, the drives
will change to the new emulation type.
If you edit this field, the new setting applies only to the next drives that are created within
the library, it is not retrospectively applied to existing drives.
Define the number of cartridge slots in the library. The number of slots available depends
upon the Emulation Type selected. Each slot is automatically populated with a new cartridge
upon creation. The cartridge capacity corresponds to the Drive Emulation type.
You can change the maximum size of the cartridge as long as it is blank. This means that
the value can only be changed after the device is created and before it is accessed by the
backup application.

The default number of drives is determined by the Emulation Type selected. If increasing the
number of drives, DO NOT exceed the maximum number of libraries and drives that a host
can physically access: see StoreOnce key parameters (page 137). The number of drives can
only be edited during library creation from this field. After library creation, there is a separate
button to Add/Remove drives.
Enables deduplication if the check box is selected (default); unselect to create a
non-deduplication library. Deduplication cannot be enabled or disabled once the library is
created.

Identifies the 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 the
interfaces that your model supports and your network configuration.
There is always one iSCSI port.

Enables configuration of the barcodes for the library to display six or eight characters. The
HP StoreOnce Backup system generates barcodes automatically for cartridges. When entering
a barcode manually, 8 characters are required. 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.
Enables Data at Rest Encryption if you applied a Security license. Encryption cannot be
enabled or disabled once a library is created; it can only be enabled at library creation. If
enabled, encryption is performed prior to writing data to disk for this library. The correct
license must be applied to enable encryption.
Enables Secure Erase if you have applied the Security license. “None” leaves it disabled
(default). To enable, select the number of preferred Overwrite Passes (1, 3, 5, or 7). This is
the number of times the data is written over after deletion. See “Secure Erase” (page 13)

NOTE: iSCSI multi-initiator mode is not supported.
To create a new library (administrators only)
HP recommends:
• Only configure the libraries that you need
• Only configure the number of cartridges that you are likely to need
NOTE: Refer to the HP StoreOnce Backup system Concepts and Configuration Guidelines,
available on the HP Support web site, for guidelines on setting up a backup policy/job within
backup applications. This document is helpful in determining the required number of libraries and
cartridges.
You can add cartridge slots at a later date to expand the system and remove individual blank
cartridges from a library without deleting the whole library.
1. To create a new library device for the host, click Create in the upper left corner of the screen.
2. Enter the appropriate details in the Device details tab (page 17).
To enable Data at Rest Encryption for the new library, configure it at this time by checking the
Encryption Enabled box. This feature requires a license. If the license is not installed, an
information message is displayed next to the check box stating Not Licensed. See “Security
Features” (page 12) and “Licensing” (page 12) for more information.
NOTE: The Replication Wizard does not allow creation of an encrypted target library. If a
replication target library needs encryption enabled, you must create the library on the target
appliance before replication mapping to it.
Libraries page 19
3. Click Create. The Cartridges tab is only generated after the library is created. The information
on the Interface Information tab is generated automatically.
NOTE: Once the library has been created, you can enable Secure Erase. See “Edit a
library” (page 20) for more information.
Guidelines on creating libraries
The table below illustrates maximum configurations for libraries and drives, but this number may

• Delete cartridges by reducing the number of slots on the Devices page. 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 further reduction on the Details page, even if previous
slots are empty. To open previous slots first use the Cartridges tab to delete the cartridge from
the slot.
• Changing the cartridge size (by changing the emulation type) on this page will only change
newly-added cartridges; it does not change the size of cartridges that were already created.
• You can reduce the number of drives but, if you go to 0, the port setting will change to "No

The Number of Drives field can only be edited during library creation. After library creation,
there is a separate button to Add/Remove drives.
• 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.
• You cannot enable or disable deduplication.
• Once the library is created and the correct license is applied, the Secure Erase Mode box
appears on the Device Details tab. The selection box defaults to None, meaning Secure Erase
is disabled. To enable Secure Erase, select the preferred number of Overwrite Passes (1, 3,
5, or 7). If enabled, this feature allows you to securely erase confidential data that may have
20 VTL (Virtual Tape Libraries) functions
unintentionally been backed up as part of a regular backup job. See “Security

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.
If Secure Erase is enabled for this store, this data will be deleted securely.
Emulation types for tape devices
HP StoreOnce Backup systems emulate a range of physical tape devices listed in Emulation types.
Table 6 Emulation types for tape devices
DescriptionEmulation type
D2DBS Generic
EML E Series
ESL E Series
If 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 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 common, but not quite
as complete as the D2DBS library type, so its not possible to use it with all backup software.
NOTE: Symantec prefers their customers use this emulation type with BackupExec and
Netbackup.
An enterprise tape library solution that allows you to configure up to 500 drives and up to
4096 cartridges per library (HP 4900 = up to 16384 cartridges per library).

IBM-TS3500
MSL G3 Series (2x24)
A tape library device that appears as a native IBM TS3500 device in a TSM environment
to allow use of standard IBM drivers. The emulation type is configured at the library level.
Therefore, all drives on a library configured with the IBM-TS3500 emulation type will use
the IBM-LTO3 drive emulation type. If the library is then changed to a different emulation
type, the drives will change to the new emulation type.
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 simultaneous
backup jobs to two devices. This emulation type is widely supported by backup applications.
Libraries page 21
Table 6 Emulation types for tape devices (continued)
DescriptionEmulation type
MSL G3 Series (4x48)
MSL G3 Series (8x96)
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 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.
A tape library device with a maximum of eight embedded Ultrium tape drives and 96
cartridge slots.
Flexible emulation
The ESL, EML and D2DBS emulations are particularly flexible because they allow you to configure
a large number of drives per library. The main benefits are that a large number of drives allows:
• more concurrent streams on backups which are throttled due to host application throughput,
such as multi-streamed backups from a database.
• a single library (and therefore deduplication 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 and Fibre Channel switch or HBA can access. See StoreOnce
key parameters (page 137).
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 .
• Refer to the HP StoreOnce Backup system Concepts and Configuration Guidelines for maximum
and recommended values.

DescriptionField
Location
Barcode
Mapped Slot
Identifies each element of the library available to hold a cartridge. The types of elements
are:
• Mail slot: a dedicated slot used to hold a cartridge that is ready for exporting to or
importing from physical tape. The Mail slot is not used with HP StoreOnce models.
• Tape drive: populated when there is activity on a cartridge. You can move a cartridge
into a tape drive by using the Move Cartridge drop-down menu in Edit mode.
• Slot n: 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 upon request.
The backup application can choose to assign its own internal identifier to the cartridge but,
if it does so, the backup application cannot assign this identifier to the Cartridge barcode.
Barcodes are generated automatically but may be edited by the user. When editing 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 are always displayed as 8 characters with letters in capitals on the StoreOnce
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
visible to the backup software, i.e. barcode 1ABCDEFG will truncate to BCDEFG.
(Truncated barcode characters are shown in brackets in the Cartridges tab.)

Empty slots
Empty slots are slots containing no cartridges and 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 and is normally only populated when
the backup application on the host is writing to or reading from the library.
• Mail slot row: This location is the slot used for importing and exporting cartridges from a
library. It is provided by StoreOnce virtual libraries for compatibility with backup applications
but is not used.
• 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 the Create button. In the Add Cartridge column, empty slots are checked.
Select individual slots by clicking the appropriate check boxes. After 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.
• If you create a cartridge in an empty slot, the backup application must inventory it (add it to
its database or catalog) before the backup application can access the cartridge.
• If you create a cartridge in an empty mail slot, use the backup application to move the blank
new cartridge to an empty cartridge slot without requiring an inventory. This saves processing
time.
Restart the backup application services to see the new cartridges.
To delete a cartridge (administrators only)
To delete individual cartridges, select individual slots by clicking the appropriate check boxes in
the Delete Cartridge column. Then click Delete.
Libraries page 25
CAUTION: A dialog is displayed, warning that all data will be lost and asking you to confirm
the Delete action.
NOTE: You cannot delete cartridges that are currently in drives, that are mapped for replication,
or that are in the delete pending, erase pending, or creating state.
If you click Cancel, the cartridges will not be deleted and you remain in delete mode. Click Delete
to continue and the selected cartridges will be deleted. The GUI does not differentiate between
cartridges with data and blank cartridges.
NOTE: You can also delete cartridges by reducing the number of slots on the Devices page, but
this only removes the highest slots with no or blank cartridges. Once the Delete operation reaches
a slot number that contains a cartridge with data, it will not reduce the number further on the Details
page even if earlier slots are blank. First use the Cartridges tab to reconfigure the slots to a blank
state.
To delete all or a range of cartridges (administrators only)
To delete all the cartridges in the library at once, click Delete All. This opens a window with several
options:
• Delete — Remove cartridges (default): completely deletes the cartridges
• Erase — Erase cartridge data: deletes the data but leaves the cartridge configurations intact
You can also determine which cartridges to delete or erase:
• All Cartridges
• Range: enter the first and last slot to be included in the delete or erase.
Finally, if you select the “Delete cartridges with data” check box, cartridges containing data will
be deleted. If unselected, only blank cartridges are deleted. After all of the options are selected,
click OK. A confirmation box appears; click OK.
NOTE: You cannot delete cartridges that are currently in drives, that are mapped for replication,
or that are in the delete pending, erase pending, or create state.
To write protect a cartridge (administrators only)
1. Click Edit for the selected library.
2. Check the Write Protected check boxfor the cartridge(s).
26 VTL (Virtual Tape Libraries) functions
3. Click 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 this value is editable. 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 the selected library.
2. Select a value from the drop-down menu, and click Update.
To move or unload cartridges
You can move cartridges, but only to an empty Location (tape drive or numbered slot).
• Click the Move button. The Move Cartridge drop-down menu lists available empty slots. (Empty
numbered slots are created when a cartridge is deleted.)
• Use the Unload all Cartridges button to return all cartridges to default slots.
Libraries page 27
The move and unload options may be useful to re-align the library configuration against the backup
application. For example, if the backup application has crashed or if the backup application does
not support the Move Medium command, the library and the backup application can become out
of sync.
NOTE: You cannot move or unload cartridges that are in the delete pending, erase pending, or
create state.
Make Replication Target libraries visible to the host
NOTE: See Replication functions (page 50) 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! Use with care. If the backup application can see both source and target libraries,
the application cannot distinguish between the source library and the target library because the
barcodes are duplicated in the two locations.
Why make target libraries visible?
It may be useful to make a target library visible to the backup application on the host to:
• Confirm replication is working correctly and check the integrity of the replicated backup by
doing a test restore.
• Perform manual tape copy jobs (sometimes called tape offload) 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.
28 VTL (Virtual Tape Libraries) functions
Best practices for using this feature
WARNING! Failure to follow best practices may cause instability and damage to your backup
system and data. Cartridges can be marked as unusable or the backup application can attempt
to write to target cartridges.
• Verify no replication jobs to the selected target cartridge are in progress.
• Verify no backup jobs to the mapped source cartridges are scheduled.
• Verify 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 with 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 64), 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 iSCSI Port.
5. Click Update.
6. Make the target library visible from other hosts. Configure the Fibre Channel fabric to make
the host visible. Target visibility persists even if the power fails or if the replication mapping
is removed.
NOTE: To remove target visibility, reset the Port to None.

4 NAS functions
This page provides access to the following StoreOnce NAS functions:
• NAS Configuration (page 30), allows users to configure CIFS and NFS servers and permissions
• Shares (NAS) (page 43), allows users to view and manage NAS shares
NAS Configuration page
Select NAS from the StoreOnce menu item to display the NAS configuration page.
Two tabs allow configuration of a CIFS Server or an NFS Server for the shares.
• The CIFS server provides CIFS interface shares that provide backup targets to Windows servers.
See CIFS Server tab (page 30).
• The NFS server provides NFS interface shares that provide backup targets to UNIX and Linux
servers. See NFS Server tab (page 42).
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 the appliance and all NAS CIFS shares created on it.
• Create NAS CIFS shares on the HP StoreOnce Backup system. See Creating a CIFS
share (page 45).
Configuring the CIFS server
1. Select NAS on the StoreOnce GUI.
2. Select the CIFS Server tab. It displays the authentication settings.
NOTE: The CIFS Server tab also shows the SMB Signing field. This feature improves security
at the protocol level and will be available in an upcoming release.
3. Click Edit to modify the authentication settings.
Three authentication options provide different levels of security for CIFS NAS shares: None
(default), User, and AD (Windows Active Directory). Before configuring the settings, determine
the appropriate setting for the particular network and collect any additional information that
may be required to complete the configuration.
NOTE: AD authentication joins the StoreOnce Backup system to an AD domain and is not
unique to NAS shares. It is also required when adding external users or external groups from
an AD domain to the StoreOnce Backup system, see User Management (page 114).
