Chapter 1. Hot-swapping a disk drive in a DM240S or DM120S

disk shelf

You can hot-swap a failed disk drive in a DM240S or DM120S disk shelf—nondisruptively replace a disk

drive in a system that is powered on and serving data (I/O is in progress). When a disk drive fails, the system

logs a warning message to the system console indicating which disk drive has failed. In addition, the

attention (amber) L D on the operator display panel and the attention (amber) L D on the failed disk drive

illuminate.

Before you begin

• The disk drive that you are installing must be supported by the DM240S or DM120S disk shelf.

Lenovo Press

• All other components in the system must be functioning properly; if not, contact technical support.

• The disk drive you are removing must be failed.You can verify the disk drive is failed by running the

storage disk show -broken command. The failed disk drive appears in the list of failed disk drives. If it does

not, you should wait, and run the command again.

Note: It can take up to several hours for the disk drive to appear in the list of failed disk drives.

• If you are replacing a self-encrypting disk (S D), you must follow the instructions for replacing an S D in

the Disks and Aggregates Power Guide. The instructions describe additional steps you must perform

before and after replacing an S D.

ONTAP 9 Disks and Aggregates Power Guide

About this task

• You should take steps to avoid electrostatic discharge ( SD):

– Keep the disk drive in the SD bag until you are ready to install it.

– Open the SD bag by hand or cut the top off with a pair of scissors.

Attention: Do not insert a metal tool or knife into the SD bag.

– Always wear an SD wrist strap grounded to an unpainted surface on your storage enclosure chassis.

If a wrist strap is unavailable, touch an unpainted surface on your storage enclosure chassis before

handling the disk drive.

• You should take steps to handle disk drives carefully:

– Always use two hands when removing, installing, or carrying a disk drive to support its weight.

Attention: Do not place hands on the disk drive boards exposed on the underside of the disk drive

carrier.

– You should place disk drives on cushioned surfaces, and never stack disk drives on top of each other.

– You should be careful not to bump disk drives against other surfaces.

• Disk drives should be kept away from magnetic devices.

Attention: Magnetic fields can destroy all data on the disk drive and cause irreparable damage to the disk

drive circuitry.

• Best practice is to have the current version of the Disk Qualification Package (DQP) installed before hot-

swapping a disk drive. Having the current version of the DQP installed allows your system to recognize

and utilize newly qualified disk drives; therefore, avoiding system event messages about having non-

current disk drive information. You also avoid the possible prevention of disk partitioning because disk

drives are not recognized. The DQP also notifies you of non-current disk drive firmware.

Lenovo Data Center Support

• Best practice is to have the current versions of disk shelf (IOM) firmware and disk drive firmware on your

system before adding new disk shelves, shelf FRU components, or SAS cables. Current versions of

firmware can be found on the Lenovo Support Web site.

Lenovo Data Center Support

• Disk drive firmware is automatically updated (nondisruptively) on new disk drives with non current

firmware versions.

Note: Disk drive firmware checks occur every two minutes.

• If needed, you can turn on the disk shelf's location (blue) L Ds to aid in physically locating the affected

disk shelf:

storage shelf location-led modify -node node_name -shelf-name shelf_name -led-status on

A disk shelf has three location (blue) L Ds: one on the operator display panel and one on each IOM12

module. Location L Ds remain illuminated for 30 minutes. You can turn them off by entering the same

command, but using the off option.

• If needed, you can refer to the Monitoring disk shelf L Ds section for information about the meaning and

location of disk shelf L Ds on the operator display panel and FRU components.

Step 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.

Step 2. Properly ground yourself.

Step 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: Lenovo requires that all returned disk drives be in a SD-rated bag.

Step 4. Physically identify the failed disk drive from the system console warning message and the

illuminated attention (amber) L D on the disk drive.

Note: The activity (green) L D on a failed disk drive can be illuminated (solid), which indicates the

disk drive has power, but should not be blinking, which indicates I/O activity. A failed disk drive has

no I/O activity.

Step 5. Press the release button on the disk drive face, and then pull the cam handle to its fully open

position to release the disk drive from the mid plane.

When you press the release button, the cam handle on the disk drive springs open partially.

Note: Disk drives in a DM120S disk shelf are arranged horizontally with the release button located

on the left of the disk drive face. Disk drives in a DM240S disk shelf are arranged vertically with the

release button located at the top of the disk drive face.

The following illustrations show disk drives in a DM120S disk shelf:

Step 6. Slide out the disk drive slightly to allow the disk to safely spin down, and then remove the disk drive

from the disk shelf.A disk can take up to one minute to safely spin down.

Note: When handling a disk drive, always use two hands to support its weight.

Step 7. Using two hands, with the cam handle in the open position, insert the replacement disk drive into

the disk shelf, firmly pushing until the disk drive stops.

Note: Wait a minimum of 10 seconds before inserting a new disk drive. This allows the system to

recognize that a disk drive was removed.

Note: Do not place hands on the disk drive boards that are exposed on the underside of the disk

carrier.

Step 8. Close the cam handle so that the disk 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 disk

drive.

Step 9. If you are replacing another disk drive, repeat Steps 3 through 8.

Chapter 1.Hot-swapping a disk drive in a DM240S or DM120S disk shelf 3

Step 10. Verify the disk drive's activity (green) L D is illuminated.When the disk drive's activity L D is solid

green, it means the disk drive has power. When the disk drive's activity L D is blinking, it means

the disk drive has power and I/O is in progress.

Step 11. If you disabled disk ownership automatic assignment in Step 1, manually assign disk ownership,

and then reenable disk ownership automatic assignment if needed:

a. Display all unowned disks: storage disk show -container-type unassigned

b. Assign each disk: storage disk assign -disk disk_name -owner owner_name

You can use the wildcard character to assign more than one disk at once.

c. Reenable disk ownership automatic assignment if needed:

storage disk option modify -node node_name -autoassign on

You need to reenable disk ownership automatic assignment on both controllers in an HA pair.

Step 12. If you are instructed to return the failed part, follow all packaging instructions and use any

packaging materials that are provided.

Chapter 2. Hot-swapping a disk drive in a DM600S disk shelf

You can hot-swap a failed disk drive in a DM600S disk shelf—nondisruptively replace a disk drive in a

system that is powered on and serving data (I/O is in progress). When a disk drive fails, the system logs a

warning message to the system console indicating which disk drive has failed. In addition, the attention

(amber) L D on the operator display panel, the attention L D on the drawer containing the failed disk, and

the attention L D on the failed disk drive (visible when the drawer is open) illuminate.

Before you begin

• The replacement disk drive must be supported by the DM600S disk shelf.

Lenovo Press

• All other components in the system must be functioning properly; if not, contact technical support.

• The disk drive you are removing must be failed.You can verify the disk drive is failed by running the
