The expiration date is not relative to the tape, but to the savesets on the tape!
- First solution: label the tape next week...
- Other solution: list the savesets on the tape, and check the expiration date of each:
mminfo -s <server> -q "volume=<volumename>,!ssrecycle" -r savetime,ssbrowse,ssretent,name,ssid
then change the retention for the savesets:
nsrmm -S <ssid> -w<date_browse> -e<date_exp>
