I've done some searching, and I have seen info about a Max Disk StgPool size 
but not a Max Volume in a Stgpool.  I have a ticket open with Tivoli, but was 
wondering if anyone knew off hand.

Here's what we tried
                
        TSM Env = AIX 5.2.x TSM 5.2.3.4 - IBM p630 4x4

We have a Clarrion with SATA Disk and (600GB Chunks Across 5 STA Disks) Our AIX 
Admin tried to present a Raw logical of 1.2TB and TSM would barf with an 
internal Server Error when we did a "dev vol disk_backup /dev/rtsmbackup 
acc=readw" (no format size needed for raw partitions).  To move forward we have 
been using 900 GB Raw Partitions and all is well.

Thanks,

Charles
