Be careful with how many disk pool volumes you create.  Each volume uses
1 thread, add this to all of the other threads in use, our TSM server
would die at around 1800 active threads.

Subject: [ADSM-L] Random Access Disk Pools

I have heard in the past that random access disk pools can become
fragmented and practically unusable after a while.  I was wondering
if anyone sees this in the real world?  I posted the other day about
managing predefined volumes in a file type devclass, and the only
answer I got said they were using random access pools.  I would MUCH
rather have a random access pool, so if there is no problem with
this, I will convert over to random access.  Thanks for any input.
