Tim,

if you define a volume to be in a storagepool, and the maxscratch for that
pool is zero, TSM will use only the tapes in that pool for backup... if the
tapes are all full, backups will fail. Remember that you need at least one
empty tape in a pool to be able to do reclaimation.

Setting up a separate pool is indeed the way to go. You could look into the
colocation options on a storagepool to see if that is what meets your
demands, in that case you could have multiple systems with more or less
identical requirements all use the same storagepool....
