I disable the onboard Perc4/Di and put in a Perc4/DC which I purchased used) with a new scsi cable. The system booted the RAID-5 array just fine. OS is RHEL 3. However, I'm still getting frequent i/o errors:
Nov 10 14:02:09 dauphin_fly kernel: I/O error: dev 08:07, sector 19312 megamgr still tells me for all three ST336753LC (Rev. DX10) drives: No Predictive Failures Media Errors: 0 Other Erros: 0 I'll shut down and remove the memory chip and battery modules. Maybe I'm unlucky now with onboard and add-in controllers both having bad memory chips.
