Just thought I'd keep you posted on our trials and tribulations with a 3 
disk raid set.

IBM suspected that it might have been because the 3 disk raid set was 
added when the system was down.  The system would have came up and decided 
these disks were empty, let's put all the temp files on these drives and 
beat the stuffing out of them.  So, this last weekend we did a Step-Mode 
Manual IPL.  Early on we broke out and did a WRKDSKSTS and sure enough 
they were out of balance.  This would be before the temp files were built. 
 Ran the STRASPBAL *CAPACITY.  Got them into balance.  Continued on. Still 
the performance is unacceptable.  However we did rule out the temporary 
file issue.  The ball is back in IBM's court.

We don't have a problem with the SPENDMONEY command.  However, as a 
service to IBM and our midrange community we thought we'd pursue this 
problem and see why we are having this issue.  We're not the first.  But 
according to IBM we're the first to actually pursue it and not just do the 
SPENDMONEY solution.

We're aware that a 3 disk raid set is inefficient in striping and wastes 
disk versus the vast improvements in a 4 drive set.  Not expecting this 
performance hit though.
