Go to device monitor in the admin console
The pending request will be at the bottom of the screen
As long as you are sure the right tape is in the drive then drag the request onto the stand alone tape drive in the window above
Once labelled NetBackup should be able to read the header and so will know what tape is in thetape drive but first time around, or until that tapes are labelled you need to do this
Hope this helps

Thanks Mark, I did not know this - I actually tried another tape, and it is ripping along now at 23000KB a second. Excellent.
Shame the normal PX502 is so much slower.
FOr the Quantum 502 robot - we have 6 jobs going to 2 drives/tapes averaging 1364KB a sec each, should we change the max jobs / multiplexing to get better throughput on the 502?
job 1 - 2514 KB/sec
job 2 - 1196 KB/sec
job 3 - 1193 KB/sec
job 4 - 1027 KB/sec
job 5 - 1071 KB/sec
job 6 - 1185 KB/sec
should this not add to about 46000KB (two drives@23000KB) rather than 8000?

should I disable compression on some of the Jobs - as isn't this handled in hardware?

Your performance issues is not related to this thread, right?
Compression will slow down backups. Backup speed is limited to the slowest component in the data path.

Yes sorry Marianne, I know I am breaking the conventions by switching question halfway. The original issue was solved, and I was curious about how slow this was. Thank you for your answer, I will see how much quicker it goes (and if it increases in size from 600gb)

contra - if you are happy with my solution please mark it to close the thread - if you still have performance issue open a new one so that we can look into it
Glad to have helped
