Yup it can make a BIG difference... Your mileage may vary...

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. Message ID . . . . . . : CPPEA12 Severity . . . . . . . : 99 A critical system hardware problem has occurred. Critical Message Handler has been run. Message ID . . . . . . : CPP8988 Severity . . . . . . . : 90
