LUN Trespass for Storage Port Failover

In addition to the high availability of statically imported iSCSI targets, the trespass feature is available
to enable the move of LUs, on an active port failure, from the active to the passive port of a statically
imported iSCSI target.
In physical Fibre Channel targets, which are configured to have LUs visible over two Fibre Channel N
ports, when the active port fails, the passive port takes over. Some physical Fibre Channel targets require
that the trespass feature be used to move the LUs from the active port to the passive port. A statically
imported iSCSI target's secondary pWWN option and an additional option of enabling the trespass
feature is available for a physical Fibre Channel target with redundant ports. When the active port fails,
the passive port becomes active, and if the trespass feature is enabled, the Cisco MDS switch sends a
request to the target to move the LUs on the new active port. The iSCSI session switches to use the new
active port and the moved LUs are accessed over the new active port (see
