Is disk bad or OK?

Hello,

I have RX2620 with HP-UX 11.31. The system has P400 controller with 4 disks. There is an orange light on one of disks. When I checked the controller with saconfig command, I got:
---------- PHYSICAL DRIVES ----------

Internal 2I 1 1 0x5000cca00a1693fd 146.8 GB OK

When I checked with sautil command, I got the following output for specific disk:

Re: Is disk bad or OK?

hi,

check in the syslog for error :

grep EMS /var/adm/syslog/syslog.log

Re: Is disk bad or OK?

As mentioned earlier post, check on event.log

# dmesg
# cd /var/opt/resmon/log/
# more event.log

Finally check with (dd command) to confirm disk really bad
Problems are common to all, but attitude makes the difference

The drive reported an error but appears to be functioning for now.

Several things to do:

Verify/Update all firmware on disks, controller and enclosure
Make sure OS patches are up to date
Create/Assign a Hot Spare
Reseat the drive
Replace the drive

Hi,
As orange/amber led blinks , then u can check that issue by replacing this particular disk.
