Event Time..........: Tue Feb 19 13:42:16 2008

Summary:
Disk at hardware path 0/0/1/1/0.8.0 : Device connectivity or hardware
failure


Description of Error:

The device was not ready to process requests when it received a request
from the device driver because it is in the process of becoming ready.

Probable Cause / Recommended Action:

The device may have been powered off and may be being powered on.

Alternatively, one or both of the terminators on the SCSI bus may be
missing. Install the terminators in their proper locations at the ends of
the SCSI bus.

Alternatively, the SCSI cable may have become detached from the device.
Re-attach the cable.

Alternatively, the SCSI cable may have failed. Replace it.

Alternatively, the device may be in a state where it could not process
this, or any, request. Cycle power to the device.

Alternatively, there could be more than one device having the same address
on the SCSI bus. Make all the addresses on the SCSI bus unique.

Alternatively, the total length of all cable segments on the SCSI bus
exceeds 25 meters. Replace one or more cable segments until the total
length is less than this value.

Alternatively, if all of the above fail to correct the problem, the device
has experienced a hardware failure. Contact your HP support representative
to have the device checked.

Alternatively, if messages corresponding to this condition appear in the
log for more than one device on the SCSI bus, the device adapter may be in
a state from which it cannot extract itself. Perform a system shutdown,
cycle power to the computer and wait for it to reboot.

If, after reboot, messages corresponding to this condition continue to
appear in the log for this SCSI bus, contact your HP support
representative to have the adapter checked.

[Paul Sperry]

The Description of Error: pretty much sums it up. It's either a scsi, cable, or disk proplem.

[Tim Nelson]

If you really wish to be sure then go into diags ( xstm ), select the disk info and/or logtool ( get password from ITRC ). Review the errors.

If there are many unrecoverable errors then disk needs to be replaced or reset counters and monitor for next failure.

I would save yourself some time and just replace the disk.

Hi Philemon

Definitely hw problem. If you have spare parts like disk, terminator, cable you can replace it and try to monitor again or best way is open hw ticket to HP

Best Regards
