This example shows VM entries that have migrated between VEMs:
The output shows two entries correspond to a VM before and after a VM has migrated between VEMs. The
IDs associated with the VM before migration are not deleted immediately. These IDs will be deleted in the
VMIS database after the switch IO timer expires. Until the IO timer expires, you will see two entries of the
same VM in the VMIS database.

This example shows statistics of a local switch's VMIS exchanges with locally attached hypervisor HBA
driver clients (host side) and with other VMIS agents on other switches in the fabric (switch side) by VSAN:
switch# show vmis statistics

RSCN
The Registered State Change Notification (RSCN) is a Fibre Channel service that informs hosts about changes
in the fabric. Hosts can receive this information by registering with the fabric controller (through SCR). These
notifications provide a timely indication of one or more of the following events:
• Disks joining or leaving the fabric.
• A name server registration change.
• A new zone enforcement.
• IP address change.
