Tape backup operation: swapping tapes

Posted on August 19th, 2010

Sometimes I need to pull large number of tapes from large tape library driven by Netbackup and replace them with fresh ones. Manual selection of media from Netbackup’s java GUI annoys me, so there is a small piece of shell code to batch eject of tapes from command line. Replace $HOST with your media server hostname.

if [ $# -ne 1 ]; then
   echo Usage: $0 [number of tapes to eject]
   exit 1
for  media in `vmquery -w -a |  \
awk '$3=="HCART2" && $7=="TLD" && $12 != "scratch" {print $1, $15}' \
| sort -k2 -n -r | awk '{print $1}' | head -$NUM`
if [ -z "$MEDIA_LIST" ]; then
vmchange -res -w -rh $HOST -rt tld -rn 0 -multi_eject -ml $MEDIA_LIST

After batch of tapes was loaded into your library CAP you will be prompted to empty the CAP and continue with eject.

*** Eject volume batch #1 is ready to be removed ***
        remove 10 volume(s) from media access port(s) of robot number 0 now
        (press <RETURN> to continue)
