Assigning WWNs to iSLB Initiators
An iSLB host is mapped to an N port's WWNs by one of the following mechanisms:
•

Assigning WWNs for iSLB initiators is the same as for iSCSI initiators. For information on dynamic and

previously assigned WWNs.
Making the Dynamic iSLB Initiator WWN Mapping Static
After a dynamic iSLB initiator has logged in, you may decide to permanently keep the automatically
assigned nWWN/pWWN mapping to allow this initiator to use the same mapping the next time it logs
in .
You can convert a dynamic iSLB initiator to a static iSLB initiator and make its WWNs persistent (see
"Dynamic Mapping" section on page

Making the dynamic mapping for iSLB initiators static is the same as for iSCSI. See the

Only statically mapped iSLB initiator configuration is distributed throughout the fabric using CFS.
Note
Dynamically and statically configured iSCSI initiator configurations are not distributed.
