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!

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.
