hard drive with blink yellow light

HP 877 10.20

I saw a blink yellow light at hud (hold up to about 12 hard drives) and I believe one of hard drive is failure. Am I right? If so then what am I doing next? Thanks.

Tom,

Hud?? What's a hud??

Anyway, without knowing what type of disk/array we're dealing with here, I can only guess - but I think you're correct in your diagnosis. With most arrays, you should be able to look at the individual drives and one of them should also have an error indicator light. If not the you'll need to get into diagnostics: check /var/adm/syslog/syslog.log and dmesg output for error messages that might indicate drive problems. You may need to run STM: see man cstm.

hud? I mean rack with 15 hard drives (Not 12..) Right but it hung within 1 or 2 minutes. Look like I can not check on check hard drive and syslog.log... Any idea?

Tom,

With no access to the system, you are going to have to check individual drives. What type of unit is this? Are the drives hot swappable? Is your root logical volume located on this "hud" (I can't imagine any other reason why your system would hang).

Ok, check all hard drives by using ioscan -fnC disk, will it help to find out which hard drive bad?

After reboot, I'll try and type ioscan -fnC disk and read syslog.log if I can.

Hi,

Looks like disk problem here, could u get into single user mode, do the fack of all file systems and come back to multiuser mode(init 3) and do dd for all disks
#ls /dev/dsk
c1t2d0 c2t2d0 ........

# dd if=/dev/rdsk/cxtxdx of=/dev/null bs=1024k

if any I/O error then that disk is in problem which needs replacement

let's know the result

Yeah I believe so...

How can I set up (init 3)? Just type like this 'init 3' or 'init3'? Thanks.

Tom.
