Have an HP Proliant ML350 G4 that's giving me some hard drive grief. The server has 6x72.8GB 10K ultra320 SCSI drives.
It all starts with an Event on bootup from CPQCISSE, Event ID: 24683
SCSI bus fault occurred on Storage Box box 0, , Port 0 of
Array Controller in slot 3.
This may result in a "downshift" in transfer rate for one or more hard drives on the bus.
When I look at my drive configuration, I see that drives 0, 1, 2, 3 have been downshifted to Ultra 2 Narrow. Drive 4 is running at Ultra 320 Wide (!). Drive 5 is running at Ultra 2 Wide.
I have updated all firmware on the system and hard drives, and pulled them all out and reseated the cables.
Looking at the diagnostics, I see that the Storage Enclosure and Drive Cage have a Critical saying U160 Disabled.
On the physical drive there is a warning flag about the drives being downshifted to Ultra 2.
I do see that drives 4 & 5 have a timeout as the last failed reason. I suspect the timeout on drive 4 is from when I pulled it out while the system was on earlier this month, not sure about the timeout on drive 5.
Any suggestions? Attached is the diagnostics report.
