• Best practice: The best practice is to have the current version of ONTAP software installed
before hot-adding a shelf.
Having the most current version of ONTAP software also will install the latest Disk Qualification
Package (DQP) and NVMe shelf module (NSM) firmware. The DQP 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.
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 automatic drive assignment is enabled.
◦ NSM shelf firmware and drive firmware should be updated automatically, if needed.
Firmware updates can take up to 30 minutes.
1.3. Prepare for a hot-add
You must complete the preparation tasks applicable to your HA pair before hot-adding a DM240N
drive shelf.
1.3.1. Prepare non-dedicated RoCE-capable ports for a hot-add
If your HA pair has non-dedicated RoCE-capable ports that you are using to hot-add a DM240N
drive shelf, you must make sure the ports are configured for storage use (not networking use).
Depending on your system, the RoCE-capable ports are on board the controllers, on RoCE-capable
PCIe cards, a combination of both, or on RoCE-capable I/O modules.
Before you begin
You must have met the system requirements.
Requirements for a hot-add
About this task
• For some systems, when a RoCE-capable PCIe card or I/O module is installed in a supported
slot on a controller, the ports automatically default to storage use (instead of networking);
however, it is recommended that you complete this procedure to verify the RoCE-capable ports
are configured for storage use.
• If you determine that the non-dedicated RoCE-capable ports in your HA pair are not configured
for storage use, it is a nondisruptive procedure to configure them.
