when doing a BACKUP, it told me need operator assist.

[Davor_7]

error message:
%BACKUP-W-MOUNTERR, volume 1 on _ was not mounted because
its label does not match the one requested
%BACKUP-I-OPERASSIST, operator assistance has been requested

but actually, i mount it on.
oh... what's the possible reason for that?

[Uwe Zessin · Accepted solution]

But it clearly tells the reason:

= its label does not match the one requested


You tell tell BACKUP to
/IGNORE=LABEL_PROCESSING

or use /LABEL=name

[Karl Rohwedder]

Normally, BACKUP wants to use the 1st 6 characters of the 1st savesetname on tape to be the tape label. That can be overwritten as Uwe states with /IGNORE or /LABEL.

If the thing goes wrong, a tape operator can force the mount with REPLY/TO=id "OVERWRITE".

[David Jones_21]

By default, BACKUP is fussy about ensuring the tapes it writes to have the correct label, which will be first 6 characters of the saveset name if not explicitly set with a /label qualifier. When it doesn't see the right tape, BACKUP sends a message to a staff member (i.e. operator) who can replace the wrong tape or take other corrective action. Unfortunately, the system console is usuaslly enabled to receive those messages whether or not anyone is around to read them. If you specify /noassist with the backup command, it will prompt you for action instead making an operator request.

it works when i use the /ignore
