Guys,
At $WORK we have a legacy Tivoli TSM backup system, which for some
unknown reason is currently using raw disk partitions (/dev/rdsk/....)
on SAN LUNs over Fibre Channel for it's storage. Yuck. These seem to
be defined in the file: dsmserv.dsk located in the bin directory of
the software. Wonderful.
Now I've figured out where they're defined, and I've figured out which
/dev/rdsk/c#t#d# maps to which LUN on which volume on the Netapp.
But, I've got some extra volumes that I'm not sure if they're used or
not by TSM, or even how to peek inside them so I can see when they
were last accessed.
Anyone know how TSM does these things?
The backend storage is Netapp, running OnTap 7.2, and I can see the
LUN maps. But I don't see these LUNs being accessed when I do the
following on the Netapp:
lun stats
which makes me *think* that the LUNs aren't active at all anymore.
But I'd like to look at the data on there before I just blow it away.
Mapping to another system isn't a problem. It's the TSM side of
things that I'm *completely* ignorant about.
Thanks,
John
