Hi,
One of my servers has 2 LTO drives, of which the 2nd drive is being used
as copy stgpool. But our management has decided to take away that second
drive so that it can be installed in another server. So for the past hour or
so, I have been updating our schedules etc so that nothing points to the 2nd
LTO drive. Everything seems to be going fine, except one last thing! I can't
seem to be able to do a 'delete devclass' of my 2nd LTO drive. Can any of
you guys try to point out what's wrong? I've cracked my head but I can't
seem to find any portion that points to the 2nd LTO device. This is what my
dev classes look like:

I'm trying to delete LTO_DEV2. Here's more info about it, followed by
the error message I get when I try to delete the device.

OK, so I think no big deal, it's probably still in use somewhere, so I
go ahead and try to find out where it's being used.

Everything up there looks fine to me, LTO_DEV2 is not in use, and I have
already deleted the old stgpool which was using LTO_DEV2. So I think maybe
it's in the admin schedule.

Nothing again! This is the ONLY schedule we use, we do all our scheduled
backups' via crontab. Is there anything I am missing out here? When I try to
delete the LTO_DEV2, I get ANR2354E DELETE DEVCLASS: Device class LTO_DEV2
is still referenced by one or more
storage pools, or database backup or export volumes.
I've checked the storage pools, and all do not seem to be making use of
Dev2 to me. TSM Database backup which is defined under the administrative
schedule, is going to LTO_DEV1. Which only leaves export volumes? Now what
in the world is that? I am the TSM Administrator and have not tried
exporting any volume before, so I dont think that would be the cause of the
reason. Can anyone try to advise me what is going wrong? I think my backups'
/ schedules will probably still run normally after the changes I've made (or
I hope so, at least) but I really would think it would be better for me to
get rid of the extra devclass which isn't even there.
Thanks in Advance,
Eugene
