Yes, we use the checklabel=barcode option on tapes that TSM has already
initialized in the past. If they are brand new tapes, we use 'label libvol'.
Pros: 1. Bypassing drives + using waittime=0 = quicker checkin...duh, you
knew that. 2. We did not always have available drives, or one was taken while
a checkin was in progress, which will fail a checkin job. Not good if there
are no watchful operators around. We've had that happen where an alert
operator is absent, and tapes that failed to checkin the previous day were
still in the bulk door, the next operator removes tapes (after the drm
checkout script runs) that he/she believes need to be going offsite, and
sends them off via the courier. Unless less you like putting your Sherlock
hat on and putting your spyglass to the offsite vendor's downloaded tape
inventory, comparing what you think should be in your library, just use the
checkl=b.  :)

Hi all,

We were told to use the following command to check-in tapes brought back
from the vault: 'checkin libvol 3584lib search=bulk checklabel=yes
status=scratch waittime=0

I have also checked in tapes using the checklabel=barcode option (usually
only when checking in brand new tapes), which bypasses the drives. I was
thinking this would be a much better option to use all of the time, as it
is much faster and would cause less wear and tear on the tape drives
themselves. Does anyone have any pros and cons of the two different
options, and what would you recommend.

Any info would be appreciated.

Regards,

Chris
