Resource: "/storage/events/disks/default/" with errors

[Carme Torca]

Hi,

I have one server with this error:

Sep 9 13:21:19 openview EMS [2606]: ------ EMS Event Notification ------
Value: "SERIOUS (4)" for Resource: "/storage/events/disks/default/0_7_0_0.10.31.0.0.0.0" (Threshold: >= " 3") Execute the following command to obtain event details: /opt/resmon/bin/resdata -R 170786833 -r /storage/events/disks/default/0_7_0_0.10.31.0.0.0.0 -n 170786869 -a

I have seen the ioscan:

and I doesn't understand anything, because I am using the disk: c8t0d0, and it works ok.

/dev/dsk/c8t0d0 /dev/rdsk/c8t0d0

Could anyone help me?
Thanks!,
Carmen.

First execute the command that EMS tells. Does it give any error??
It is very difficult to comment on ioscan output. Are you upto date on patches??

What does following command show??
pvdisplay /dev/dsk/cxtxdx
diskinfo /dev/rdsk/cxtxdx

Carmen,

On my server if I run ioscan -fn -H for my disks I show NO_HW as well. I know my disks and all paths are good.

Could you please run:

/opt/resmon/bin/resdata -R 170786833 -r /storage/events/disks/default/0_7_0_0.10.31.0.0.0.0 -n 170786869 -a

and post the results.

Thanks,
David

Hi Carmen,

Looks like the fiber card or the switch port on the SAM switch is acting up.

You are probably able to use the disk c8t0d0 because you have an alternate path to that disk.

Hope this helps.

Hi,

Here you are.

CURRENT MONITOR DATA:

Event Time..........: Thu Sep 9 13:21:19 2004
Severity............: SERIOUS
Monitor.............: disk_em
Event #.............: 100472
System..............: openview.t-systems.es

Summary:
Disk at hardware path 0/7/0/0.10.31.0.0.0.0 : Device connectivity or
hardware failure


Description of Error:

The device is not in a state where it can process requests. Manual
intervention is required.

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.
