TSM 4.1.3.2 (I think... 4.1 plus whatever patch they put on their site
last week) on AIX 4.3.3.
Firstly, is there a FAQ associated with this list? I have a feeling
this question may have come up before...
How do DISK volumes reclaim unused space? On a tape, since you cannot
write to the begining of a tape you are reading from, you have to copy the
data to another tape to reclaim.
On a disk volume, this should not be necessary, since you can copy
data from the middle of a volume to the begining of the volume.
I just installed a new TSM server here with disk volumes as the
primary storage pool. Should I be worried about reaching the "end" of the
disks? Will TSM fill the "holes" in each volume with new data, or will it
shift all of the data to the beginning of the volume, just moving the holes
to the end of the volume?
If not, should I put one of the volumes into a separate storage pool
and then tell TSM to reclaim my main disk pool to this second pool, and
have that pool migrate back to the main one? I would hate to do this if
it was not necessary, since it would waste a lot of good space for backups.
OTOH, I'd hate to put ALL of my disks into the one storage pool, and
then be unable to do backups due to lack of reclamation...
Right now, I have some disks that I have not used, yet (once a part
arrives, I am going to mirror the original volumes). If I wait until we
have filled the disk storage pool and see what happens, I can then recover
if backups stop by using one of the other disks as a reclamation pool. I'd
rather not trial and error on a production server, though...
