HP StoreOnce VSA Backup System User Guide (TC458-96025)

no queued or paused jobs in the backup application, or restarting backup application services. If
neither action resolves the problem, reboot the backup application server.
Catalyst troubleshooting
Since StoreOnce Catalyst is designed to allow maximum control to the client application, any
problems should be remedied by checking job configuration on the client. In the unlikely event that
the StoreOnce Catalyst Status display as Fault, contact HP support services for further advice.
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 system.
Performance
Your HP StoreOnce Backup system is designed for high performance backup and restore operations
according to the specification documented. However, it requires careful configuration. Please refer
to the HP StoreOnce Concepts and Configuration Guidelines document for detailed guidance.
There are many reasons why you may not see the performance you expected from your HP
StoreOnce Backup system.
• Your own network speed or disk access is not fast enough to allow streaming of data.
• Your backup application is not optimized. For example, there are not enough backup streams
configured to achieve optimum performance.
• Your HP StoreOnce Backup system is not optimized for your network and application.
Network
The HP StoreOnce Backup system is designed to be run on a 1Gb or 10Gb network. Performance
will be reduced if a 10/100BaseT network is used. The LEDs on the front panel (1–Gb ports only)
and on the network ports and also warnings on the Management Console will indicate the network
speeds at which the device is operating.
StoreOnce Backup system configuration problems
I cannot see a newly created VTL device
When you create a new device on the HP StoreOnce Backup system, the host will not be able to
see the device until you connect manually to it using the iSCSI Initiator or . If you cannot see the
device, check Device Manager to make sure it is visible from the host.
I cannot see additional slots from the backup application
When you create additional slots for an autoloader/library on the HP StoreOnce Backup system,
you may need to restart services on the backup application so that it can see the new slots.
I cannot recover the configuration file
You can only recover a configuration file to an HP StoreOnce Backup system if no devices (NAS
shares or Virtual Tape Libraries) have been created on that appliance. This option should only be
used in emergencies, when the HP StoreOnce Backup system has lost both disks and all disk
configuration.
Upgrade licenses
If you have installed the Instant-On demo license, you should purchase and install the appropriate
full licenses before the Instant-On license expires. See Licensing (page 12).
