i've encounter a strange issues which i hope to seek some comments and advise here before logging a call with symantec.
i've a netbackup domain configure with V.I.P to backup all the VMs in each of the 3 x ESX servers.
-policy 1 tat backups all VMs in esx1, policy 2 to backup all VMs in esx2, and policy 3 to backup all VMS in esx3.
-each esx holds abt 15 x VMs.
The backup runs fine..EXCEPT for 3 particular VMs, which always failed with 156.
-There's no snapshot stuck in these 3 x VMs from Snapshot manager in the Virtual Center.
-At datastore level as well, there is no delta-files at the VMFS volume.
i've also tried to vMotion the 3 VMs to a different host, update the VIP policy to reflect the changes, and backup will still failed with this 3 x VMs.
however, if i create a new netbackup policy that do a manual selection on these 3 VMs, backup will run successfully.
comments plz~ :)
Please check all of the snapshot options you have set for each policy - that is the only place i can see there would be something different between the policies
Maybe either a full mapping / quiecing issue
Is there anything linked between these three machines (have apps on them such as SQL / Exchange) which may be causing a quiece issue
Need a bit more from the logs on the Media Server to see exactly what the 156 error relates to
