Replacing failed disk on Server

How to check if Disk failed

Check for the light on disk:

Solid Yellow => Fail

Blinking Yellow => Predictive Failure (going to fail soon)

Green => Normal

Replace disk instruction

• Determine what machine the disk below to
• Press the red button on the disk to turn it off.
• Gently pull a little bit out (NOT all the way) and wait for 10 sec until it stops spinning before pulling all the way out.
• Find replacement with a similar disk with the same specs
• Carefully unscrew the disk from disk holder (if the disk holder part on the replacement is the same then you don't have to).

How to check if disk is failed or install correctly

1. Log into gimel as root

$ ssh root@sgehead1.bkslab.org

2. Log into the machine that you determined from earlier as root

$ ssh root@<machine_name>
Example: RAID 3,6,7 belongs to nfshead2

3. Run this command

$ /opt/compaq/hpacucli/bld/hpacucli ctrl all show config
