Getting started
The StoreOnce System Management Console
The StoreOnce System GUI and CLI together make up the Management Console.
The online help and the StoreOnce System user guide describe how to use the StoreOnce System GUI.
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 an
SSH terminal session. The StoreOnce System CLI Reference Guide describes how to use the StoreOnce
System CLI commands.
Supported browsers
The StoreOnce Management GUI is supported on the following web-browsers:
• Internet Explorer 9, 10, and 11 (note that Internet Explorer 8 is not supported and some StoreOnce
features will not work)
• Mozilla Firefox v23 and above, and Firefox ESR24
NOTE: The TLS protocol version 1.0 is no longer supported. You must manually enable TLS 1.1 or 1.2 in
your browser to access the StoreOnce GUI.
StoreOnce Graphical User Interface (GUI) components
NOTE: The web browser being used to communicate with the StoreOnce System must have Active
Scripting or JavaScript enabled. If it does not, some of the browser buttons may not be displayed.
After 15 minutes of inactivity, the session times out and returns to the Login screen.
The GUI includes:
Getting started 11
• Title bar: Displays the StoreOnce System model, the user name and role, and contains the Logout
and Help buttons.
• 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 following icons 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.
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 plus (+) sign next to a topic indicates additional options; click the plus sign to expand the
selection and click the minus sign (-) to contract the selection.
• Topic page (main window): Initially, the main window displays the top-level StoreOnce topic page. To
display the page for that selection, select another topic from the Navigator. Some Topic pages require
selection of an item, such as a service set, VTL library, NAS share, or StoreOnce Catalyst store in the
top half of the page to display details specific to the selected item in the lower half of the 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.
NOTE: For more information about service sets, see Select service set on page 14.
• Help button: The Help button in the top right-hand corner of each page displays context-sensitive
information for the current page in a pop-up window.
◦ 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 and previous pages.
◦ The information in the footer also provides navigation options. The Home link navigates to the
Home page for the help, which gives you access to the complete online help. This page also
contains Contents, Search, and Index options. You will need to resize the page to use it effectively.
Overview of the StoreOnce System page
The initial page at GUI logon provides important information about system status and processes that are
running. The StoreOnce System page also provides access to individual StoreOnce functions, which are
available as sub topics (click + to display them in the Navigator).
System Information
The System Information section of the Status page provides information unique to an individual
StoreOnce System.
12 Overview of the StoreOnce System page
Table 1: System information parameters
Parameter Description
Type The model of StoreOnce System.
Node Name The node name for this Service Set.
Serial Number The serial number of the entire cluster. Use this serial number when
contacting Hewlett Packard Enterprise Support. (It is the same as the serial
number on the License management on page 188 page.)
Cluster Management IP The IP address that provides access to the StoreOnce Management Console
(GUI and CLI) and applies to the whole cluster, not individual couplets.
Software Revision The software revision of the node on which the Service Set is running. Use
this revision when adding couplets to check that all Service Sets are running
the latest and the same software.
Data VIF IPs The Data VIF IP addresses for data. Use these addresses when configuring
backup applications to send data to the StoreOnce System. The IP
addresses can be IPv6 or IPv4 addresses.
If VLAN tagging has been configured on your network, a scrollable list allows
you to see all the VLAN IP addresses that have been configured. For more
information about VLAN tagging, see the installation planning and preparation
guide for your product.
Status
The Status provides details about the rolled-up status of the system or Service Set and the status of the
services running.
Table 2: Status parameters
Parameter Description
Service Set or Overall
Status
StoreOnce Subsystem The status of the background support processes such as Event Manager and
Virtual Tape The status of the VTL service.
NAS The status of the NAS service.
StoreOnce Catalyst The status of the StoreOnce Catalyst service.
Replication The status of the Replication service.
Housekeeping The status of the Housekeeping service.
The state of the system or service set.
Resource Manager.
Storage Usage
Getting started 13
The Storage Usage provides details about the amount of data on the system.
Table 3: Storage Usage parameters
Parameter Description
User Data Stored The amount of data written by the backup application (before deduplication)
to all stores on that service set.
Size On Disk The amount of disk space used to store the data deduplicated in all stores on
that service set.
Deduplication Ratio The deduplication ratio.
Capacity Saved The amount of capacity saved (as a percentage) by deduplicating the data.
Viewing service set information
On the lower StoreOnce main page, the screen displays parameters specific to service sets:
• Click on a service set to display status information for the services running on that set.
• Click on any column heading to change the sort order or select which columns are displayed.
• A single-couplet configuration has two Service Sets and is the minimum configuration. Additional
couplets increase Service Sets, two for each couplet, up to a maximum of eight. The following
example shows a configuration with eight Service Sets. Therefore, it has four couplets.
Table 4: Service set parameters
Field Description
Name The name of the Service Set.
Current Node The node on which the Service Set is running. This node is normally the Main
node, unless a failover state has been invoked.
Main Node The name of the node on which the Service Set normally runs.
Failover Node The name of the failover node for the Service Set.
Service Set Status The status of the Service Set, such as: Running, Starting, Fault, Not Started,
Stopped, or Unknown.
Failover Status The failover status of the Service Set. The three possible values for each
service set are: Enabled (green), Disabled (white X), and Failed Over (red).
This field is useful when running software upgrades or after a reboot to check
the failover status of Service Sets.

A service set is a collection of various services, such as VTL, NAS, Replication, and StoreOnce Catalyst.
There is one instance of each service per service set. The auto-configuration process registers and starts
a service set by launching a process on the server for each of the services.
14 Viewing service set information
Administrators can create elements such as libraries, NAS shares, replication mappings, and StoreOnce
Catalyst stores for a service set. They can also expand or contract the service sets that make up a
Federated store. When creating or modifying such an element, the system prompts you to select the
target service set to which it relates.
IMPORTANT: The number of available service sets depends on the number of couplets in the
cluster configuration. The minimum is 2 (for a single couplet in one rack), the maximum is 8 (for a
two–rack installation with four couplets).
Table 5: Select Target Service Set parameters
Parameter Description
Name The name of the Service Set. There are two for
each couplet in your cluster configuration.
Status The status of the Service Set.
Available <devices> Remaining This column is displayed when you create a library
or share and indicates how many devices you can
still create for this service set. The maximum
devices available depends upon the number of
couplets in your configuration. The maximum is 48
for a single couplet.
Why are there two service sets for each couplet?
There are two service sets for each couplet installed in the StoreOnce System rack to ensure resilience
and failover. Each Service Set has a VIF associated with it. This VIF is the IP address used to configure
replication mappings and StoreOnce VTL, NAS, or StoreOnce Catalyst devices as backup targets in the
backup application.
Each node in a couplet can run both service sets during a node failure, and each service set has its own
set of service processes and storage. Each service set is associated with:
• A primary node, the node on which it usually runs.
• A secondary node, where it will run if the primary node fails.
Each node can act as the secondary node for the main Service Set on the other. During a failover, the
service set moves transparently from the primary node to the secondary node. Because each storage
cluster in the couplet has two connections, one from each node, the service set can still access storage
on the primary node even though it is now running on the secondary node.

Powering on
To power on the appliance, you must use the StoreOnce CLI and/or power on buttons. You can shut down
or reboot the appliance using either the StoreOnce CLI or the StoreOnce Management GUI on the
Maintenance page. See Maintenance on page 187 for more information about using the StoreOnce GUI
for power off options.
IMPORTANT: It is best to failover a service set during the node power on or reboot sequence in
case of unexpected errors with the node.
NOTE: If network switches and storage enclosures have been powered off, power on those first (using
the power on switches).
After maintenance activities, both servers must be powered on at the same time so that the checks in the
code can complete before the file system starts.
Procedure
1. Power on the servers using either:
Powering on 17
• The power on button on each server to trigger a cold boot and automatically power on.
• StoreOnce CLI commands to power on a node remotely. (This method requires a server node that
is running.) For example, if a node was powered off using CLI commands, power it up again using
the following CLI command:
hardware powerup nodeX
2. After a successful power on, ensure that failover is enabled.
• To check the status of failover:
hardware show node status
• To enable failover if it is off:
system enable failover
3. Once failover is enabled, check that no service sets have failed over during any reboot sequence:
• To check the status of the service sets:
hardware show node status
NOTE: You can also use the GUI to check the status. Look at the StoreOnce System page of the
GUI and check the failover status of the service set.
• To fail them back:
system failback setX
NOTE: You can also use the GUI to failback a node. Locate the node in the Hardware pages of the
GUI and click Failback this server.
If power on is unsuccessful
IMPORTANT:
A previous unclean shutdown will lead to integrity checking of the storage and your user data.
Depending upon the amount of data stored on the couplet, this process can take several hours. Be
patient to see whether the Service Set will come online without further intervention or reboot.
If node or a couplet fails to successfully power on after a node experienced an unclean power off, power
off both nodes in the couplet (using the power buttons on the nodes if necessary). Power on one node
and then power on the other node in the couplet.
Powering off using the StoreOnce CLI
Various commands exist to shut down a node or a cluster. Use the correct command to perform the task
required. More details can be found in the StoreOnce System CLI Reference Guide.
NOTE: A power off command only powers off the server component. If the maintenance activity requires
the disk enclosure or internal network switch to be powered off, power them off manually.
18 If power on is unsuccessful
• system shutdown: This command gracefully shuts down the cluster by shutting down all services
and StoreOnce service sets before powering down the servers. when you power up, the deduplication
stores will start up from a clean state. Servers will be in the off state, and will require powering on via
the power button.
• hardware poweroff nodeX: This command uses the iLO port to turn off the server, which does not
allow StoreOnce service sets to shutdown gracefully. Deduplication stores shut down in an unclean
state and require integrity checking (an automatic process) on the next power on. To avoid this
condition, the service set on a given node should be failed over to the backup node using the system
failover setX command before powering down the node.
Rebooting the system using the StoreOnce CLI
More details can be found in the StoreOnce System CLI Reference Guide.
Use the following CLI commands to reboot your system:
• system reboot: This command gracefully reboots the cluster by shutting down all services and
StoreOnce service sets before rebooting the servers. This means on reboot the deduplication stores
will start up from a clean state.
• hardware reboot nodeX: This command uses the iLO port to reboot the server, which does not
allow StoreOnce service sets to reboot gracefully. The result is deduplication stores shutting down in
an unclean state and requiring integrity checking (an automatic process) on reboot.
The following sequence is recommended if you wish to reboot a node in a controlled way. It fails over the
service set before rebooting the node.
1. system enable failover
2. system failover setX
3. system reboot nodeX
Once nodeX has completed reboot, use system failback nodeX.
Rebooting the system using the StoreOnce CLI 19
VTL (Virtual Tape Libraries)
VTL Licensing requirements
• No licensing is required for VTL emulations unless using the Security features Data at Rest
Encryption, Data in Flight Encryption, and Secure Erase.
• VTL (or NAS) replication requires a license on the target site, but only if replication is used.
VTL replication requires a replication license per couplet, for each couplet in the appliance.
• Replication encryption using IPsec is part of the Security license. See

Viewing the VTL configuration
Select VTL from the StoreOnce System Navigator menu to display the current VTL configuration.
The following functions are available from the StoreOnce–VTL page:
• VTL configuration, which allows an administrator to manage the interface settings for libraries.
• Library and cartridge management.
NOTE: Equivalent StoreOnce CLI commands are available for the tasks described in this section. See the
StoreOnce System CLI Reference Guide.
The top half of this page displays available service sets. Click on the service set to display the Fibre

Used. Warnings occur if the port is not available or is down. They also appear
if the system is unable to obtain Speed information. Errors occur if there is a
fault or the system cannot obtain the link status.
Table Continued
Setting Description
Speed The default is Auto, which is the recommended option. The speed will be
auto-negotiated between the switch and StoreOnce appliance to choose the
highest supported speed. For users who wish to fix the speed, other values
are available, as follows: 16Gbs, 8Gbs, 4Gbs, or 2Gbs (not recommended).
Topology The default is N_Port, when a single target device creates many virtual
devices on a fabric attached port. N_Port requires the switch port to support
NPIV (N_Port ID Virtualisation).
Beacon Individual ports can be “beaconed” via the GUI. This toggles an LED on the
physical HBA. The color of this button changes to show the current status of
the beacon; grey is off, blue is on.
Editing the Fibre Channel settings
Prerequisites
Only administrators can edit the Fibre Channel settings.
Procedure
1. Navigate to StoreOnce > VTL > Fibre Channel Settings tab.
2. Click Edit to make the fields configurable for each port.
3. Make the preferred changes to the speed and/or topology, and click Update.
CAUTION: This update resets the Fibre Channel link and may affect any backup or restore jobs
running.
NOTE: Fibre Channel settings apply to the whole appliance. The settings can also be edited in the
StoreOnce Catalyst section of the GUI if you are backing up to StoreOnce Catalyst target devices over
Fibre Channel. Fibre Channel settings, defined on either page, apply to all target devices being
backed up over Fibre Channel. Therefore, any changes here will also apply to StoreOnce Catalyst
target devices over Fibre Channel and conversely.
Changing the port speed causes the port status to be reported as Down; refresh the VTL Configuration
page to verify that the port is back online. Check the Hardware Tree and the Events page to see the
change.
4. Click Continue at the warning prompt to continue applying the changes.
Changes affect all service sets running on the node.
Port assignment for StoreOnce Systems with multiple Fibre Channel ports
When creating a library, you can select one or multiple Fibre Channel ports for the Library controller
virtual robotics interface. The Fibre Channel settings identify both the HBA card and the port number that
will be used. For example, HBA-6.Port1 is Port 1 on the Fibre Channel card in slot 6.
Editing the Fibre Channel settings 21
Drives within a virtual library can only appear on one Fibre Channel port. If you select multiple ports for
the library robotics controller, the drives are automatically distributed evenly across the ports to ensure
best performance and failover. After creating the library, it is possible to change the drive assignments
using the edit function on the Interface Information tab for the selected library. See Viewing the Interface
Information on page 32.
Disabling library Auto Creation

Parameter Description
Name Identifies the selected device (library). Hewlett Packard Enterprise
recommends using a name that identifies the host or backup job with which it
is associated.
Replication Role The role of the library, which may be non-replicating, replication source or
replication target.
Status The status of the library, which may be online, offline, not started, failed to
start, stopping, creating, port not present, or deleting.
Connection 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.
Device Type The emulation type used by the backup software. It is selected when you
create a device.
Cartridges/Slots The number of cartridges or slots available on the device, which is
determined by the Emulation Type selected when the device was created;
see Emulation types for tape devices on page 30. You can reduce the
number of slots in the Device Details tab for a library selected on this page,
but this reduction only removes the highest empty slots. Once it reaches a
slot number that contains data, you cannot reduce the number further on this
page, even if earlier slots are blank. First use the Cartridges tab to make the
slot empty.

24 VTL (Virtual Tape Libraries)
Field Description
Physical Data Size Quota This quota is for the amount of data written to disk after deduplication. The
minimum quota size is 50 GB. If the quota is enabled and the quota limit is
reached, backups will fail to prevent the quota from being exceeded. The
quota allows you to partition the physical capacity of the appliance
between various users.
NOTE: If capacity management is required, Hewlett Packard Enterprise
recommends configuring backup applications with quotas to reroute to
another device or to postpone backups to prevent backups from failing
unexpectedly.
When a library reaches its quota, the status of the library will change to
“Critical”. Restores from that library are permitted but new backups will
fail. When the quota is no longer met, either by increasing the quota or by
expiring backups, the library status returns to the “OK” state.
Logical Data Size Quota This quota is for the amount of data a user sends to the device before
deduplication. The minimum quota size is 50 GB. If the quota is enabled
and the quota limit is reached, backups will fail in order to prevent the
quota from being exceeded. This allows you to provide a service to back
up a particular amount of user data. For example, set this quota when you
charge customers per TB of user data protected.
NOTE: If capacity management is required, Hewlett Packard Enterprise
recommends configuring backup applications with quotas to reroute to
another device or to postpone backups to prevent backups from failing
unexpectedly.
When a library reaches its quota, the status of the library will change to
“Critical”. Restores from that library are permitted but new backups will
fail. When the quota is no longer met, either by increasing the quota or by

Emulation
The StoreOnce appliance supports HPE and IBM Library and drive emulations.
Library Emulation The emulation type of the library. The StoreOnce System supports a
number of emulation types.
See also Emulation types for tape devices on page 30. The emulation
type determines the available embedded drives and cartridge slots. For
example, if you select 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.
Table Continued
VTL (Virtual Tape Libraries) 25
Field Description
Default Drive Emulation The drive emulation type, LTO–2, 3, 4, 5 or 6, determines the default
capacity of the newly created cartridges within the library device. Tape
cartridge capacities can be changed individually at any time but cannot be
reduced to smaller than the current used size.
If you selected D2DBS Generic for the Library Emulation, 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, Hewlett
Packard Enterprise 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. Drives on a library configured with
IBM-TS3500 IBMi will use the IBM-LTO5 drive emulation type. If the library
is then changed to a different emulation type, the drives will change to the
default drive emulation type of LTO4.
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.
Number of Cartridge Slots 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.
Number of Drives 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.
The number of drives can only be edited during library creation from this
field. After library creation, there is a separate button to add and remove
drives.
See Key Parameters on page 247 for detailed specifications.
Cartridge Size The size of the cartridge in GB. This field is only available during creation
of the cartridge.
See Key Parameters on page 247 for detailed specifications.
Number of Barcode
Characters
Enables the barcodes for the library to display six or eight characters. The
StoreOnce System generates barcodes automatically for cartridges. When
entering a barcode manually, eight characters are required. If the 6–
character barcode is selected, the StoreOnce System will truncate to six
characters, removing two characters of an 8–character barcode. For
example, barcode 1ABCDEFG will truncate to BCDEFG. The barcode is
displayed with the truncated characters in brackets on the Cartridges tab,
(1A)BCDEFG.
Table Continued
26 VTL (Virtual Tape Libraries)
Field Description
Barcode Template Enabled Enables configuration of the barcodes. A barcode is an 8– or 6–character,
alpha-numeric, unique identifier for a cartridge within the StoreOnce
System. The backup application will normally track cartridges using
barcodes but may also alias the cartridge with another name in its
database. (IBM emulations only support 8–character barcodes.)
By default, barcodes are generated automatically but may be determined
by a barcode template created when the library is created. If using
barcode templates, the barcode template:
• Must be unique and must not start with the letters “CLN” or “DG”
because these combinations are reserved designations for cleaning
and diagnostic cartridges.
• Can have a prefix of up to three alpha-numeric characters, a start
value, and a suffix of up to two alpha-numeric characters.
Any unspecified prefix or suffix characters will increase the length of
the variable field of the barcode.
• Should be a minimum of 6 characters. Valid ASCII characters are A-Z,
a-z, 0–9. Barcodes are always displayed as eight characters with
letters in capitals on the StoreOnce Management 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 six
characters will be visible to the backup software, that is, barcode
1ABCDEFG will truncate to BCDEFG. (Truncated barcode characters
are shown in brackets in the Cartridges tab.)
You can modify the barcode template after library creation by clicking
Modify Barcode Template on the Device Details tab.

Creating a library
HPE recommends the following to avoid complication when configuring the backup application, and also
to avoid creating additional Fibre Channel SAN traffic:
• Only configure the libraries that you need.
• Only configure the number of cartridges that you are likely to need.
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.
The maximum number of virtual devices supported varies according to the product and this number is
split across VTL, NAS, and StoreOnce Catalyst devices. See Key Parameters for more information.
Prerequisites
Only administrators can create libraries.
Procedure
1. Navigate to StoreOnce > VTL > Libraries
2. Click Create in the upper left corner of the screen.
3. Select a service set for the new library and click OK. The information on the service set identifies how
many libraries are still available.

Deleting a library 29
CAUTION: Take care when changing the Port configuration because the system does not
automatically reassign any drives that may now be configured incorrectly. For example, if you
change from a multiple Fibre Channel port configuration to a single Fibre Channel port, manually
correct those drives that are connected to the wrong port when the status shows ready and
restarted. See Viewing the Interface Information on page 32.
5. Click Update.
Notes:
It is possible to edit some, but not all, device details after creating a library.
• Delete cartridges by reducing the number of slots on the Devices page. This reduction 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 Port".
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 (for example,
the number of cartridges).
• 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 unintentionally been backed up
as part of a regular backup job. See Security features on page 199 and License management on
