Automatic switch over storage unit in SLP if storage unit is down.

This issue has been solved. See solution.

Hi Experts,

Backups are getting failed to the Storage Appliance if it is gets down. So need to plan the alternate solution/automation of manual steps to avoid the manual change of storage unit in the policy. And delay in firing the Backups.

What is the command to change a storage unit in SLP so that i can put in a batch file script that checks if one storage A is down it should switch to B or if B is down it should switch to A.

Create a Storage Unit Group and change SLP to use STUG instead of STU.

Choose appropriate failover criteria.
Extract from NBU Admin Guide I:

■ Prioritized. Choose the first storage unit in the list that is not busy, down, or out of media.
■ Failover. Choose the first storage unit in the list that is not down or out of media.
■ Round Robin. Choose the least recently selected storage unit in the list.
■ Media server load balancing. Choose a storage unit based on a capacity-managed approach.

Just take note not to use STUG if you're running AIR

'Note: If creating an SLP for Auto Image Replication, do not select a storage unit group. Auto Image Replication does not support replicating from a storage unit group. That is, the source copy cannot be in a storage unit group.'
