Re: [Networker] Tape Retirement Process....

hi,

The following command can be used to display the date that volumes were
originally labeled

mminfo -a  -r "volume,olabel"


and number of mounts can be found using the following command output.

mminfo -m

Not very sure if any backup software can count 'tape passes ' as such.

Regards
Shyam

Hi Siobhan,
Thanks for your reply. Is there any way to keep track of tape passes and
load/unload cycles to retire a tape??

Thanks,
Srinivas Rao S.
