HP StoreOnce VSA Deployment and Configuration Guide (TC458-96024)

Power issues
The VSA service set goes down and file system becomes read-only
The VSA service set goes down and file system becomes read-only when external ESXi storage
LUNs are disconnected from the server.
Cause
This behavior may be seen when the connection to the ESXi storage is lost and recovered while
the VSA is powered on and running.
Solution
The StoreOnce VSA may become unresponsive in this case. Contact HP Support for assistance at
http://www.hp.com/support.
IMPORTANT: Do not reboot or shutdown the VSA when any storage operation is in progress.
Use the StoreOnce CLI command, system show status, to verify that storage addition is
completed and the storage is formatted before any shutdown or reboot operation. An uncontrolled
shutdown/reboot/power outage may result in file system inconsistencies.
Backup jobs on VTLs fail after power shutdown
Cause
This behavior may be caused due to various reasons.
Solution
The VTL should be displayed in a “Connected” state on the StoreOnce GUI when the StoreOnce
VSA is powered on.
If it is in a “Not Connected" state, try the following steps:
1. Login to the ISCSI Initiator of your Client and remove the current StoreOnce VSA.
2. After removing the StoreOnce VSA from the iSCSI initiator, re-discover it through the ISCI
initiator and try connecting the robotics medium changer and VSA drives.
3. Login to the StoreOnce GUI and check that the status of the library is connected
For NetBackup, please follow these additional steps:
1. Use NetBackup to remove drives for the library (only the drives and not the robot).
2. Restart NetBackup Device Manager.
3. Create the drives manually for the library on top of the existing robot.
4. Restart NetBackup Device Manager.
5. Restart failed jobs again.
Repeat the steps above if the issue reoccurs.
