Chapter 1. Hot-swapping a drive
You can replace a failed drive nondisruptively in an DM240N drive shelf that is po ered on, and hile I/O is
in progress.
Before you begin
• The drive that you are installing must be supported by the DM240N shelf. Lenovo press
• If SED authentication is enabled, you must use the SED replacement instructions in the ONTAP
documentation. Instructions in the ONTAP documentation describe additional steps you must perform
before and after replacing an SED.
ONTAP 9 Lenovo Encryption Po er Guide
• All other components in the system must be functioning properly; if not, contact technical support.
• Verify that the drive you are removing is failed. You can verify that the drive is failed by running the storage
disk show -broken command. The failed drive appears in the list of failed drives. If it does not, you should
ait, and then run the command again.
Note: Depending on the drive type and capacity, it can take up to several hours for the drive to appear in
the list of failed drives.
About this task
• Best practice: The best practice is to have the current version of the Disk Qualification Package (DQP)
installed before hot-s apping a drive. Having the current version of the DQP installed allo s your system
to recognize and use ne ly qualified drives. This avoids system event messages about having noncurrent
drive information and prevention of drive partitioning because drives are not recognized. The DQP also
notifies you of noncurrent drive firm are.
Lenovo Do nloads: Disk Qualification Package
• Best practice: The best practice is to have current versions of NVMe shelf module (NSM) firm are and
drive firm are on your system before replacing FRU components.
Note: Do not revert firm are to a version that does not support your shelf and its components.

• Drive firm are is automatically updated (nondisruptively) on ne drives that have non current firm are
versions.
Note: Drive firm are checks occur every t o minutes.
• If needed, you can turn on the shelf's location (blue) LEDs to aid in physically locating the affected shelf:
storage shelf location-led modify -shelf-name shelf_name -led-status on If you do not kno the shelf_
name of the affected shelf, run the storage shelf show command.
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 hen you return the failed
drive. You return the failed part to Lenovo as described in the RMA instructions shipped ith the kit. If you
need the RMA number or additional help ith the replacement procedure, contact technical support at
Lenovo Support, 888-463-8277 (North America), 00-800-44-638277 (Europe), or [phone] (Asia/
Pacific).

Step 1. If you ant to manually assign drive o nership for the replacement drive, you need to disable drive
o nership automatic assignment if it is enabled.
Note: You need to manually assign drive o nership if drives in the shelf are o ned by both
controller modules in the HA pair.
Note: You manually assign drive o nership and then reenable drive o nership automatic
assignment later in this procedure.
a. Verify hether drive o nership automatic assignment is enabled: storage disk option show
You can enter the command on either controller module.
If drive o nership automatic assignment is enabled, the output sho s on in the “Auto Assign”
column (for each controller module).
b. If drive o nership automatic assignment is enabled, disable it: storage disk option modify
-node node_name -autoassign off
You must disable drive o nership 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 arning message to the system console indicating hich
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), hich indicates that the
drive has po er, but should not be blinking, hich 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 ith your other
hand.
Step 5. Wait a minimum of 70 seconds before inserting the replacement drive.
This allo s the system to recognize that a drive as 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 slo ly so that it aligns correctly ith 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 po er. When the drive's activity
LED is blinking, it means that the drive has po er and I/O is in progress. If the drive firm are 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 o nership automatic assignment in Step 1 on page 2 , manually assign drive
o nership, and then reenable drive o nership automatic assignment if needed:
a. Display all uno ned drives: storage disk show -container-type unassigned
You can enter the command on either controller module.
2Service Guide for DM240N

b. Assign each drive: storage disk assign -disk disk_name -owner owner_name
You can enter the command on either controller module.
You can use the ildcard character to assign more than one drive at once.
c. Reenable drive o nership automatic assignment if needed: storage disk option modify -node
node_name -autoassign on
You must reenable drive o nership automatic assignment on both controller modules.

Chapter 2. Hot-swapping a power supp y
You can replace a failed po er supply nondisruptively in an DM240N drive shelf that is po ered on, and
hile I/O is in progress.
About this task
• If you are replacing more than one po er supply, you must do so one at a time so that the shelf maintains
po er.
• Best practice: The best practice is to replace the po er supply ithin t o minutes of removal from the
NSM module.If you exceed the t o minutes, the shelf continues to function, but ONTAP sends messages
to the console about the degraded po er supply until the po er supply is replaced.
• Best practice: The best practice is to have current versions of NVMe shelf module (NSM) firm are and
drive firm are on your system before replacing FRU components.
Note: Do not revert firm are to a version that does not support your shelf and its components.

Step 1. Properly ground yourself.
Step 2. Physically identify the failed po er supply.
The system logs a arning message to the system console indicating hich po er supply failed.
Additionally, the attention (amber) LED on the shelf operator display panel illuminates and the
bicolored LED on the failed po er supply illuminates red.
Step 3. Disconnect the po er cord from the po er supply by opening the po er cord retainer, and then
unplug the po er cord from the po er supply. Po er supplies do not have a po er s itch.
Step 4. Remove the failed po er supply:
a. Rotate the cam handle to its open (horizontal) position, and then grasp it.
b. With your thumb, press the blue tab to release the locking mechanism.
c. Pull the po er supply out of the NSM module hile using your other hand to support its
eight.
Step 5. Insert the replacement po er supply:

a. Using both hands, support and align the edges of the po er supply ith the opening in the
NSM module.
b. Gently push the po er supply into the NSM module until the locking mechanism clicks into
place.
Attention: Do not use excessive force or you might damage the internal connector.
c. Rotate the cam handle to the closed position.
Step 6. Connect the po er cord to the po er supply and secure the po er cord ith the po er cord
retainer. When functioning correctly, a po er supply's bicolored LED illuminates green.
