Use the following procedure to create FC initiator groups.
Create and manage initiator groups on the Initiators screen. Click the add icon to view unaliased ports. Click a WWN in the list to add a meaningful alias in the Alias field.
On the Initiators page, drag initiators to the FC Initiator Groups list to create new groups or add to existing groups.
