I have a customer who has just migrated a number of VM's from one vCenter environment to another, and following this all of the said VM's are failing the backups with a 156 error. After investigation I notice that Netbackup is still communicating with the 'old' vCenter server - and trying to perform a snapshot on it - rather than the new vCenter where the VM's now reside.
Both of the vCenter servers are known to Netbackup and credentials OK.
I seem to recall a caching issue here, whereby NBU needs to have a cache location cleared ?? I have created a new policy and added one of the VM's in question as a client - but it still tries to perform a snapshoot on the old vCenter server !! I have also re-booted one of the VM's in question - and no joy - same issue.
Whilst I think I recall reading of this issue I cannot find the information now........
Any help appreciated.
