About WWW Assignment for iSCSI Initiators
An iSCSI host is mapped to an N port's WWNs by one of the following mechanisms:
- Dynamic mapping (default)With dynamic mapping, an iSCSI host is mapped to a dynamically generated port WWN (pWWN) and node WWN (nWWN). Each time the iSCSI host connects, it might be mapped to a different WWN. Use this option if no access control is required on the Fibre Channel target device (because the target device access control is usually configured using the host WWN). The following three dynamic initiator modes are supported:
- Static mappingWith static mapping, an iSCSI host is mapped to a specific pWWN and nWWN. This mapping is maintained in persistent storage. so each time the iSCSI host connects, the same WWN mapping is used. This mode is required if you use access control on the target device.
