Why do you need to cache disk pool volumes ?? Are you going to restore
just in the middle of backup. Or migrate to tape during backup.
I prefer to create disk pool volumes to raw devices and let TSM spread the
load. And it does this pretty well.

Subject:        Re: TSM Server 4.2.1.9 on Sun Solaris 8 and more

I have a SUN 880 connected to a HDS 7700E diskarray using VxVM and VxFS on
the db and log volumes. I use the mount parameter mincache=direct or
unbuffered and I must say the performance is good. I will test with raw
soon to se how it's working.

Do anyone of you know how TSM handles the disk storage pools volumes? Are
they cached as the db and log are by TSM or are they dependant of the
filesystems buffers.
