Chapter 1. Hot-swapping a drive

You can replace a failed drive nondisruptively in an DM240N drive shelf that is powered on, and while 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.

• 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

wait, 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-swapping a drive. Having the current version of the DQP installed allows your system
to recognize and use newly 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 firmware.

Best practice:

The best practice is to have current versions of NVMe shelf module (NSM) firmware and

drive firmware on your system before replacing FRU components.

Note:

Do not revert firmware to a version that does not support your shelf and its components.

• Drive firmware is automatically updated (nondisruptively) on new drives that have non current firmware

versions.

Note:

Drive firmware checks occur every two 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 know 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 when you return the failed

drive. You return the failed part to Lenovo as described in the RMA instructions shipped with the kit. If you
need the RMA number or additional help with the replacement procedure, contact technical support at
