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) LED on the operator display panel, the attention LED on the drawer containing the failed disk, and 
the attention LED 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 

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 (SED), you must follow the instructions for replacing an SED in 

the 

Disks and Aggregates Power Guide

. The instructions describe additional steps you must perform 

before and after replacing an SED.

ONTAP 9 Disks and Aggregates Power Guide

About this task

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

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

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

Attention:

Do not insert a metal tool or knife into the ESD bag.

–  Always wear an ESD 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.
