Hot-adding a DM240N drive shelf
You can hot-add a second DM240N drive shelf to an existing HA pair when additional storage is needed.
Before you begin
• Your system and version of ONTAP must support the DM240N shelf.
Lenovo press
• Your system cannot have any storage cabling error messages. Correct any storage cable errors before
proceeding.
• You need a paper clip with one side straightened or a narrow tipped ballpoint pen.
You use the paper clip or ballpoint pen to access the shelf ID button through the small hole, to the right of
the LEDs, in the Operator Display Panel (ODP).
About this task
• Best practice: The best practice is to have the current version of the Disk Qualification Package (DQP)
installed before hot-adding a shelf.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 adding a new shelf.
Note: Do not revert firmware to a version that does not support your shelf and its components.

• After you have cabled a hot-added shelf, ONTAP recognizes the shelf:
– Drive ownership is assigned if drive ownership automatic assignment is enabled.
– NSM firmware and drive firmware should be updated automatically, if needed.
Note: Firmware updates can take up to 30 minutes.
Preparing controller non-dedicated ports for a hot-add
Before hot-adding a second shelf to your system, you must verify that controller non-dedicated (secondary)
storage ports (e0b and e0e) are enabled for storage use (not data use). If the e0b and e0e ports are not
enabled for storage use, you must enable them.
About this task
Enabling the e0b and e0e ports for storage use is a nondisruptive procedure (your HA pair continues to serve
data when you reboot the controller modules).
Step 1.
Verify that the e0b and e0e ports on both controller modules are in the
storage port show
You can enter the command on either controller module.
