Symptoms

In order to check the disk LED status, use cs_hal to identify this. You can also turn on and off the notification LED if you need an onsite engineer to confirm you are working on the correct drive.

This is applicable to Gen 1, Gen 2, and Gen 3 hardware.

Cause

You must determine disk LED status.

With the block device, check the status of the disk LED: 
# cs_hal locate /dev/sdj status
/dev/sdj: OFF
Turn on and turn off the disk LED, as below: 
# cs_hal locate /dev/sdj start
cs_hal: setting LOCATE state of disk /dev/sdj to 'ON'

# cs_hal locate /dev/sdj stop
cs_hal: setting LOCATE state of disk /dev/sdj to 'OFF'
Check all the disks LED status on a node with the below command: 
# for X in $(alldisks); do echo -n "${X}  "; cs_hal info ${X} | grep Locate; done
