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 (see the
You can convert a dynamic iSLB initiator to a static iSLB initiator and make its WWNs persistent.
Making the dynamic mapping for iSLB initiators static is the same as for iSCSI. See the
Note
Dynamic iSLB Initiator WWN Mapping Static" section on page
Only statically mapped iSLB initiator configuration is distributed throughout the fabric using CFS.
Note
Dynamically and statically configured iSCSI initiator configurations are not distributed.

Assigning VSAN Membership for iSLB Initiators

Individual iSLB hosts can be configured to be in a specific VSAN (similar to the DPVM feature for Fibre
Channel; see
overrides the iSCSI interface VSAN membership.
Note Specifying the iSLB initiator VSAN is the same as for an iSCSI initiator. See the
for iSCSI" section on page
When an iSLB initiator is configured in any other VSAN (other than VSAN 1, the default VSAN), for
Note
example VSAN 2, the initiator is automatically removed from VSAN 1. If you also want it to be present
in VSAN 1, you must explicitly configure the initiator in VSAN 1.
See the

Configuring Metric for Load Balancing

You can assign a load metric to each initiator for weighted load balancing. The load calculated is based
on the number of initiators on a given iSCSI interface. This feature accommodates initiators with
different bandwidth requirements. For example, you could assign a higher load metric to a a database
server than to a web server. Weighted load balancing also accommodates initiators with different link
speeds.
