bus adapter (or the WWN) from below one of the ports and change the nickname to hba1,
the host bus adapter below the other port will also be renamed hba1.

Changing the name or host mode of a host group
The Storage Administrator (Provisioning) role is required to perform this task.
Use LUN Manager to change the name or host mode of a host group. You can change only the
host mode option of the host group for the initiator port. You cannot use this procedure on the host
group for the external port.
CAUTION:
Before changing the host mode of a host group, you should back up data on the port
to which the host group belongs. Setting host mode should not be destructive, but data integrity
cannot be guaranteed without a backup.
