Offline Disks

Hello,

For some reason i don't know why, the HP-UX (11.0) cannot "see" my Database disks.

Reading the root mail i can see some scary messages:

IRMD[Warning]: Adapter 0/3/0/1 LDrv 0 State Change from OPTIMAL to DEGRADED

and later,

IRMD[Warning]: Adapter 0/3/0/1 PDrv 2:12 State Change from ONLINE to FAILED.

Can anyone help me on this?

Thanks in advance,

Knight

You may get more info by reading your /var/adm/syslog/syslog.log file and connecting to the console and look at the hardware log.

Regards,

Fred

What is the output of ioscan -fnC disk? Are the drives mirrored? Try
dd if=/dev/dsk/cXtXdX of=/dev/null bs=512 & if command hangs disk def dead.

Re: Offline Disks

Sounds like your adapter has failed "Adapter 0/3/0/1 PDrv 2:12 State Change from ONLINE to FAILED"...

Put a call in to HP and have them look...

Re: Offline Disks

Hi,

You have problem :(
One of your disk is falure, and after that secound. After that you lose your LUN and all data.
If you have RAID 5
DEGRADED= one disk from your RAID is falure.
System still work but performance is bad.
You need to raplace disk.

FAILED=CTL or second disk falure. You lose your data. Replcae falure components and restore your backup

Hi,

How are you on the patch side.

Do you have patch PHSS_27097 which i think is needed for your configuration,

Or you may have a faulty hardware.

Hope this helps.

Re: Offline Disks

Hello,

Thanks for all the help.

I have an array of 4 disks with raid 5.
Don't know why but one of the disks got problems (Degradeded state in mail root or syslog) and few minutes after a second disk went down (Offline state).

I call HP which put the second disk Online and then replaced the first one.

No need to do any restore and the second disk will be replaced soon.

Thanks again for the help.
