You can use the iSCSI Wizard to configure a new or existing initiator on a switch.
To use the iSCSI Wizard, follow these steps:
There are three options. The Auto option assigns the WWN from a pool of about 440,000 WWNs per switch and is returned to pool when you log out. The Persistent option also assigns the WWN from a pool. However, when you log out of the switch, the WWIN is not returned to the pool but is saved for the initiator. The third option is to statically assign the WWN by manually entering WWN that the initiator will use.
