Chapter 37 Configuring and Managing VSANs
Configuring VSANs
Operational State of a VSAN
A VSAN is in the operational state if the VSAN is active and at least one port is up. This state indicates
that traffic can pass through this VSAN. This state cannot be configured.
About Static VSAN Deletion
When an active VSAN is deleted, all of its attributes are removed from the running configuration.
VSAN-related information is maintained by the system software as follows:
• VSAN attributes and port membership details are maintained by the VSAN manager. This feature is
affected when you delete a VSAN from the configuration. When a VSAN is deleted, all the ports in
that VSAN are made inactive and the ports are moved to the isolated VSAN. If the same VSAN is
recreated, the ports do not automatically get assigned to that VSAN. You must explicitly reconfigure
the port VSAN membership (see Figure 37-4).
Figure 37-4 VSAN Port Membership Details
•
VSAN-based runtime (name server), zoning, and configuration (static routes) information is
removed when the VSAN is deleted.
• Configured VSAN interface information is removed when the VSAN is deleted.
Note The allowed VSAN list is not affected when a VSAN is deleted (see Chapter 35, “Configuring VSAN
Trunking”).
Any commands for a nonconfigured VSAN are rejected. For example, if VSAN 10 is not configured in
the system, then a command request to move a port to VSAN 10 is rejected.
