I have an IBM xSeries with an IBM ServeRAID controller running
openSUSE 10.1. Previously, for years, this server ran SuSE 9.2 and
was absolutely ROCK solid. However, now it is constantly logging I/O
errors, but no drive ever goes offline. It really seems to be a
problem with the logical drive.
ipssend says:
Controller type : ServeRAID-3L
Actual BIOS version : 7.12.02
Firmware version : 6.10.24
Boot block version : 3.00.21
Device driver version : 7.12.05
And there are four active drives, and one hot spare. Each report as
active with no PFA. The status of the logical drive is "Okay"
But dmesg is full of:
sd 0:0:0:0: SCSI error: return code = 0x70000
end_request: I/O error, dev sda, sector 4319748
sd 0:0:0:0: SCSI error: return code = 0x70000
end_request: I/O error, dev sda, sector 4319748
sda is the logical drive
