• If you are hot-adding a shelf to an HA pair that already has an NS224 shelf, your HA pair cannot have any
storage cabling error messages, and it must be cabled as multipath HA.
You can run Active IQ Config Advisor to view any storage cabling error messages and the corrective
actions you should take.

• You need a paper clip with one side straightened or a narrow tipped ballpoint pen.
To change the shelf ID, you use the paper clip or ballpoint pen to access the shelf ID button behind the
Operator Display Panel (ODP).
Considerations for a hot-add
You should familiarize yourself with best practices and aspects about this procedure
before hot-adding an NS224 drive shelf.
• 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 run Active IQ Config Advisor before and after hot-adding a shelf.
Running Active IQ Config Advisor before hot-adding a shelf provides a snap shot of the existing shelf
Ethernet (ENET) connectivity, verifies NVMe shelf module (NSM) firmware versions, and allows you to
verify a shelf ID already in use in the HA pair. Running Active IQ Config Advisor after hot-adding a shelf
allows you to verify shelves are cabled correctly and that shelf IDs are unique within the HA pair.

• 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.

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:
â—¦ Drive ownership is assigned if automatic drive assignment is enabled.
â—¦ NSM shelf firmware and drive firmware should be updated automatically, if needed.
Firmware updates can take up to 30 minutes.
