How many HBA host ports do I need to select?

You can have multiple in each .

Hosts with multiple HBA host ports can have multiple connections to the storage subsystem. All HBA host ports must be selected as part of the mapping to provide maximum redundancy. When you create the mapping, make sure that you select all of the HBA host ports that you have connected to the storage subsystem.


Important:

If you are configuring host access manually, you must select all of the HBA host ports in the host from the list of Known HBA host ports. Add these HBA host ports to the list of Selected HBA host port identifiers/aliases for the host that you are configuring.

For example, a host might have two HBAs, each with two HBA host ports that are connected to the storage subsystem. For this host, you would select four HBA host ports.
