Step 1. If you want to manually assign drive ownership for the replacement drive, you need to disable drive
ownership automatic assignment if it is enabled.
Note: You need to manually assign drive ownership if drives in the shelf are owned by both
controller modules in the HA pair.
Note: You manually assign drive ownership and then reenable drive ownership automatic
assignment later in this procedure.
Verify whether drive ownership automatic assignment is enabled: storage disk option show
a.
You can enter the command on either controller module.
If drive ownership automatic assignment is enabled, the output shows
column (for each controller module).
If drive ownership automatic assignment is enabled, disable it: storage disk option modify
b.
-node node_name -autoassign off
You must disable drive ownership automatic assignment on both controller modules.
Step 2. Properly ground yourself.
Step 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.
Note: 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.
Step 4. Remove the failed drive:
a. Press the release button on the drive face to open the cam handle.
b. Slide the drive out of the shelf using the cam handle and supporting the drive with your other
hand.
Step 5. Wait a minimum of 70 seconds before inserting the replacement drive.
This allows the system to recognize that a drive was removed.
Step 6. Insert the replacement drive:
a. With the cam handle in the open position, use both hands to insert the replacement drive.
b. Push until the drive stops.
c. Close the cam handle so that the drive is fully seated into the mid plane and the handle clicks
into place.
Be sure to close the cam handle slowly so that it aligns correctly with the face of the drive.
Step 7. Verify that the drive's activity (green) LED is illuminated.
When the drive's activity LED is solid, it means that the drive has power. When the drive's activity
LED is blinking, it means that the drive has power and I/O is in progress. If the drive firmware is
automatically updating, the LED blinks.
Step 8. If you are replacing another drive, repeat Step 3 on page 2 through Step 7 on page 2.
Step 9. If you disabled drive ownership automatic assignment in Step 1 on page 2 , manually assign drive
ownership, and then reenable drive ownership automatic assignment if needed:
Display all unowned drives: storage disk show -container-type unassigned
a.
You can enter the command on either controller module.
