When I had this problem at a previous job, we originally were going to wait
until the weekend to replace the failed cache battery (the performance hit
wasn't supposed to be very bad).  By the time 2 hours had gone by, we
changed our mind on that because batch jobs that had any I/O at all were
taking about 3 times longer than usual.  We ended up installing the battery
that night!

We finally got thru our fix of disk cache batteries (iSeries 810 only
perhaps 4 years old).
The only clue we had was that the system became extremely slow during a
conversion test, running about 3 times slower. The CE claimed it shouldn't
have hit us that hard. I think otherwise - we were running large cpylib,
many chgpf's of big files, and adding 7 gig of files w/RPG to existing 10
gig.
Manager asking if I can prove it was the batteries (this was our final test
before go-live).
Can anyone else confirm losing cache batteries could cause such an effect?

btw- our only clue of hardware problem was wrkdsksts & F11 screen showed
disks in "degraded" status. After an ipl, we did get following 2 msgs in
qsysopr queue:
* *Attention*  Contact your hardware service provider now.
