"failed, status 6" error after increasing datastore (LUN) capacity
We seem to consistently have this issue where when we increase the capacity of a LUN on the SAN storage side and expand the datastore in vCenter with this capacity increase, NetBackup will throw back a "failed, status 6" error when attempting to use the san transport mode. There are no backup issues until this capacity increase takes place. Example of the log we see:
- begin writing
- Error bpbrm (pid=39403) from client vm_name: ERR - Error opening the snapshot disks using given transport mode: san Status 23
- Critical bpbrm (pid=39403) from client vm_name: FTL - cleanup() failed, status 6
- Error bptm (pid=39602) media manager terminated by parent process
All zoning is correct so there's nothing on the fabric side preventing connectivity. For vCenter and ESXi we are running a later version of 7 update 3. On the SAN side we are running IBM FlashSystem storage. Our NetBackup version is a flavor of 10.3.0. Does anyone have thoughts as to why this happens and how we can prevent it from happening in the future?
Hey
Did you rescan the LUNs after resize on the backup host? I think in vxms logs you would see some logs indicating that the LUN expected size is and actually it is the other - thus NBU gets confused.
If you did run rescan - try with rebooting the media server/backup host which sees the expanded LUNs. This should solve your issues.
