Assigning WWNs to iSLB Initiators

An iSLB host is mapped to an N port's WWNs by one of the following mechanisms:
•
•
Note Assigning WWNs for iSLB initiators is the same as for iSCSI initiators. For information on dynamic and
static mapping, see the
We recommend using the SystemAssign system-assign option. If you manually assign a WWN, you

must ensure its uniqueness (see the Cisco MDS 9000 Family NX-OS Fabric Configuration Guide for
more information). You should not use any 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
the
You cannot convert a dynamic iSCSI initiator to a static iSLB initiator or a dynamic iSLB initiator to a

static iSCSI initiator.
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.
To permanently keep the automatically assigned nWWN/pWWN mapping, follow these steps:
