-node node_name -autoassign off
You need to disable automatic drive 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.
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.
5. Open the drawer containing the failed drive:
a. Unlatch the drive drawer by pulling on both levers.
b. Using the extended levers, carefully pull the drive drawer out until it stops.
c. Look at the top of the drive drawer to find the Attention LED that resides on the drawer in front of each
drive.
6. Remove the failed drive from the open drawer:
a. Gently pull back the orange release latch that is in front of the drive you want to remove.
