Steps
1. If you want to manually assign disk ownership for the replacement disk drive, you need to disable
disk ownership automatic assignment if it is enabled; otherwise, go to the next step.
Note: You need to manually assign disk ownership if disk drives in the stack are owned by both
controllers in an HA pair.
Note: You manually assign disk ownership and then reenable disk ownership automatic
assignment later in this procedure.
a. Verify if disk ownership automatic assignment is enabled:
storage disk option show
If you have an HA pair, you can enter the command at the console of either controller.
If disk ownership automatic assignment is enabled, the output shows “on” (for each
controller) in the “Auto Assign” column.
b. If disk ownership automatic assignment is enabled, you need to disable it:
storage disk option modify -node node_name -autoassign off
You need to disable disk ownership automatic assignment on both controllers in an HA pair.
2. Properly ground yourself.
3. Unpack the new disk drive, and set it on a level surface near the disk shelf.
Save all packaging materials for use when returning the failed disk drive.
Note: NetApp requires that all returned disk drives be in a ESD-rated bag.
4. Identify the failed disk drive from the system console warning message and the illuminated amber
attention LED on the drive drawer.
The 2.5-inch and 3.5-inch SAS drive carriers do not contain LEDs. Instead, you must look at the
Attention LEDs on the drive drawers to determine which drive has failed.
The drive drawer's Attention LED (amber) blinks so you can open the correct drive drawer to
identify which drive to replace.
The drive drawer's Attention LED is on the front-left side in front of each drive, with a warning
symbol on the drive handle just behind the LED.
