Hi Peter!
A delete volume runs as fast (or as slow) as a delete filespace. Actually, it
does the very same thing: delete every single object from the database one by
one.
If the node had it's own tapes, you could mark all it's tapes in both the
primary pool and the copy pool destroyed and let do the expire inventory do the
work for you...
Kindest regards,

Subject: del filesp with +10Mio files
Hi TSM'ers
on the following system I'm faced to delete ca. 15 filespaces holding a
total of ca. 30 Mio files.
HW: IBM H70, 2GB, SSA + SAN disks
OS: AIX 5.3 ML 04
TSM: 5.3.3, 60 GB DB on SSA & mirrored on SAN, 2 GB LOG ( SSA + SAN)
Doing individual
del filesp node file_space_name
will take days/weeks/months(?) (the biggest filespace owns ca. 19 Mio files).
The filespaces are all on collocated nodes, i.e. I could even do:
1. Determine the volumes for nodes' data
2. Either
create backupsets of the nodes data to be kept, just
to keep the current state
or
run a selective backup with a different MGMT-class,
sending the data to a different set of tapes
3. run "del vol <volid> discard=yes" for all the volumes
belonging to the node
4. proceed as normal after having finished
Questions:
----------
Q1. Is the sequence of steps 1. - 4. faster than the individual
"del filesp node filespace_name"
Q2. Any idea to do it even faster ?
