Hi,

Just run the command

/opt/resmon/bin/resdata -R 179896346 -r /storage/events/disks/default/0_5_0_0.8.0 -n 179896331 -a

and see what you get. The output you get will have a detailed description and a recommendation/solution.

If there is a real lun on lun 0 then you have a real problem.

I do suspect however that ioscan -fnC disk will show there is no actual lun0 presetnted to this system by your fiber card/disk array setup.

What happens when no lun is assigned and presented as lun0 is that your HP system picks up the disk array itself. It thinks its a disk but it really isn't.

Maybe you san admin can think of a way to keep that from happening. We stopped it merely by making sure one of the luns presented to each fiber card is lun0.

That's not a fibre disk, that is a local SCSI attached disk and looks like an internal disk on the N4000.

Do an 'ioscan -fnC disk' and see if the disk at hardware path 0/5/0/0.8.0 shows NO_HW. If it does, then that is your problem.

If this disk was bad at one time in the past and has been replaced, then try the following:

# /etc/opt/resmon/lbin/set_fixed -n /storage/events/disks/default/0_5_0_0.8.0

That should reset the disk in EMS so that it is no longer shown as down. Then monitor your syslog and see if the even occurrs again. If it does, then you probably have a disk problem. If it doesn't then it was an old message that was just ocurring repeatedly because it was never reset within EMS.
