Agreed the question seems silly. However I recently on two identical
brand new POWER8 servers running i 7.1 had a task that was VERY heavily
I/O bound on all IFS work. On the one server the task took 78 seconds.
On the other it took over 90. MINUTES.
IBM was not so friendly in helping. Performance data said that 100% of
cache writes were failing (cache full). Despite the disk units being
only about 5% busy, they sent the problem to hardware because 'it must
be a bad cache battery'. (Not only was it not, there are none in the
servers!) In the end the problem was not actually ever figured out BUT
re-installing 5770SS1 option 3 suddenly solved the problem. Option 3 was
flagged in error when we ran the network verify component of ARE. Oddly
CHKPRDOP *OPSYS had NOT flagged this.
