The most obvious reasons would be a tape operator running a check-in script 
instead of a label script or checking in with a status=private instead of 
status=scratch.

TSM will not initialized a tape with data it knows about, so checking them out 
and labeling or checking back in as scratch (whichever is appropriate) will 
work.  If you check everything out with remove=no, and checkin scratch first 
and then private, you should get back all the volumes that have been 
initialized.  If you are still missing some, they probably haven't been 
initialized.

As for the volhist, a volume isn't listed there until it is actually used for 
data of some kind.

Subject: [ADSM-L] unaccounted for volumes

Tsm server 6.2.2 running on RHEL v6 with a 3494 library and 8 ts1120 drives.

Was doing some checking on tape inventory and usage for one of our tsm servers.

A

Select count(*) from libvolumes

Shows 298 volumes in the library.

Checking volhistory for database backup volumes shows 3 tapes in that capacity.

Check of pending volumes shows 1

And summing up all tape pool volumes gives 118.

A
Select count(*) from libvolumes where status='Private'

Shows 160
And
Select for scratch volumes gives 137.

The upshot is that I have around 40 volumes in the libvolumes table listed as 
private, but not accounted for in the volumes or volhistory?
Audit library ields no errors.

Can I just check these out and re check them in as scratch?

What would account for this.

p.s.

I have the volhist file from the moment the server was placed online.  The lost 
volumes do not appear there anywhere.

Thanks for any help.
