Your HA pair must meet certain requirements before hot-adding an NS224 drive shelf.
For each shelf you are hot-adding, you need a minimum of two RoCE capable ports on each controller. These ports can be on board the controllers, on RoCE capable PCIe cards, a combination of both, or on RoCE capable I/O modules, as supported by your platform model.
If your HA pair does not have enough available RoCE capable ports, and your platform model supports the use of RoCE capable PCIe cards or I/O modules, you must have installed the additional cards or I/O modules into the correct controller slots, as supported by your platform model.
The core dump module installation instructions can be found on the "AFF and FAS System Documentation Center".
Replacing the caching module or adding/replacing a core dump module
You cannot have exceeded the maximum number of shelves supported by your HA pair after hot-adding shelves.
You can run Active IQ Config Advisor to view any storage cabling error messages and the corrective actions you should take.
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).
