Persistent FC ID Configuration Guidelines

When the persistent FC ID feature is enabled, you can enter the persistent FC ID submode and add static or
dynamic entries in the FC ID database. By default, all added entries are static. Persistent FC IDs are configured
on a per-VSAN basis.
When manually configuring a persistent FC ID, follow these requirements:
• Ensure that the persistent FC ID feature is enabled in the required VSAN.
• Ensure that the required VSAN is an active VSAN. Persistent FC IDs can only be configured on active
• Verify that the domain part of the FC ID is the same as the runtime domain ID in the required VSAN.
• Verify that the port field of the FC ID is 0 (zero) when configuring an area.
