Prepare to hot-add NS224 shelves to your ASA system by ensuring sufficient RoCE-capable storage ports, configuring them for storage use, and optimizing your existing configuration for the new shelf.
What to prepare
Preparing to hot-add NS224 shelves to your ASA system involves verifying and configuring the storage connectivity infrastructure before physically installing new shelves. These tasks ensure your HA pair has the necessary RoCE-capable Ethernet ports and that your system is configured to support additional storage capacity.
The specific preparation tasks you need to complete depend on your platform model, current configuration, and the number of shelves you are adding:
- Install RoCE-capable PCIe cards or I/O modules
-
Verify your system has enough available RoCE-capable Ethernet ports (two per shelf on each controller). If additional ports are needed, install RoCE-capable PCIe cards or I/O modules in the correct controller slots.
- Configure RoCE-capable ports for storage use
-
If you are using non-dedicated RoCE-capable ports to connect the NS224 shelf, configure those ports for storage use instead of networking use. This is a nondisruptive procedure.
- Recable existing shelves
-
For some platform models, you might need to recable an existing shelf across two sets of ports in different slots to provide resiliency against slot failure after installing additional RoCE-capable PCIe cards or I/O modules.
- Disable automatic drive assignment
-
If you plan to manually assign drive ownership, disable automatic drive assignment before hot-adding shelves.
