I recently upgraded from 7.6.1 to 7.6.3, but after the upgrade my NDMP backups are running slow. I rolled back to 7.6.1 and my NDMP backups still run slow. No network changes or new LUNs were created on our NetApp appliance.
I did notice a few command switches in a string under each NDMP job; however, I am not sure if this is still accurate due to the performance issue.
Does anyone have a cheat-sheet on the command switches used in the NDMP string for jobs? I am suspecting that I had a customized string, and somehow it was over written.
I updated recently NW from 188.8.131.52 to 184.108.40.206 and backing up Celerra I could not see any difference in performance - it stayed just the way it was before (FC attached tapes).
