A shelf has three location LEDs: one on the operator display panel and one on each NSM module.
Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command,
but using the
off
option.
• When you unpack the replacement drive, save all packing materials for use when you return the failed

Steps
1. If you want to manually assign drive ownership for the replacement drive, you need to disable automatic
drive assignment if it is enabled.
You need to manually assign drive ownership if drives in the shelf are owned by both
controller modules in the HA pair.
You manually assign drive ownership and then reenable automatic drive assignment later in
this procedure.
a. Verify whether automatic drive assignment is enabled:
storage disk option show
You can enter the command on either controller module.
If automatic drive assignment is enabled, the output shows
on
in the
Auto Assign
column (for each
controller module).
b. If automatic drive assignment is enabled, disable it:
storage disk option modify -node
node_name -autoassign off
You must disable automatic drive assignment on both controller modules.
2. Properly ground yourself.
3. Physically identify the failed drive.
When a drive fails, the system logs a warning message to the system console indicating which drive failed.
Additionally, the attention (amber) LED on the drive shelf operator display panel and the failed drive
illuminate.
The activity (green) LED on a failed drive can be illuminated (solid), which indicates that the
drive has power, but should not be blinking, which indicates I/O activity. A failed drive has no
I/O activity.
4. Remove the failed drive:
a. Press the release button on the drive face to open the cam handle.
