Hello List -

TSM 5.2.3
z/OS 1.5

When I came on board as the TSM Admin eight months ago, my site had 46 db 
volumes of 500MB each.  Since that time, I've had to increase the DB a few 
times, so (not knowing otherwise), I've added 4 more volumes of 500MB each.  I 
have no complaints about system performance, as we are backing up 200 nodes and 
get through most days without problems.  But, we are a growing system and I 
want to make sure we are properly positioned for the future.

If I consolidate the database over fewer volumes (say, 10 2500MB volumes, 
rather than 50 500MB volumes), will there be any performance gains?  So far, 
the only reason I can see to do it, is to have fewer volumes to declare during 
a database restore at the DR site, and I'd like to have more of a reason to 
undertake the task.

Also, if I do move forward with the volume consolidation, should I do a 
UNLOADDB, LOADFORMAT, LOADDB first?  Will that lead to smoother database 
maintenance?

Thanks in advance.
