We pulled the plug on our old Legato backup server a short
while ago, which had 2 qualstar 46120 libraries with AIT1
tape drives.

We decided to try and hook one of the these qualstar's
up to our TSM server (3494 with Magstars).  We got it up
and configured in tsm, but when we go and try to
label tapes we get errors - I've listed the errors
at the end of this email.

Now, the strange thing.  This library has 3 AIT1 drives.
Two of them get these errors, but the 3rd works!!!!!!  So we've
been able to label tapes and use them, but only with
one drive.  Any attempt to label tapes, or read used
tapes with the two drives fails.  If I try and use the
drives directly from aix (ie: tar to them), they work fine.
They also worked under Legato.

We tried our other Qualstar library also.  It also has 3
drives - all 3 fail in exactly the same way.

I made sure that the dip switches (not scsi addr jumpers)
on the drives are all set to the same positions as the
one drive that works.

I updated the drives with the latest microcode, but
this didn't help.

I'm stumpted!
        - all drives work in aix
        - only one drives works with tsm
        - latest microcode
        - dip switches set like good drive
        - all drives did work in Legato

Any thoughts?

Thanks

Rick
