Netbackup version is Appliance 5220.
The customer has a tape A which is stored NBU image previously, but all the images in A had been expired prior to this issue happened.
The customer put the tape A in the A pool, and there is only A tape in A pool, then the customer start up the backup to pick up the A tape from A pool, but they saw the error 96 immediately after the backup start up. Change the tape A into B pool, stracth pool also the same result.
The available_media command shows the A tape is available status.
From GUI, I found out the owner of the A tape is NONE since it's blank tape.
bplabel command failed with the below two type errors:
2013-12-2 15:42:57 - Error nbjm (pid=10956) NBU status: 800, EMM status: Media is not in pool
error requesting media (tpreq) (98)
Error nbjm (pid=10956) NBU status: 2015, EMM status: Media is expired
error requesting media (tpreq) (98)
It seems that the tape can't be labeled even it's really a blank tape.
The command
we confirm the robtest can move the problematical tape into the driver.
And the tpreq command can also mount the tape successfully.
In addition, the mt command can rewind the tape, and the tar command can write the ect/host file into this tape.
But I am not aware of why the bplabel command failed with the issue appearing that:error requesting media (tpreq) (98). And the tape can't be selected during the backup process which resulted in the 96 error.
The issue got resolved after I did the below two things:
vmdelete -m A
Then inventory the robot to add the tape back in emm database.
However, may I get your further clarification of the possible reason?
