About Persistent FC IDs

When persistent FC IDs are enabled, the following occurs:
•
•
If you connect to the switch from an AIX or HP-UX host, be sure to enable the persistent FC ID feature
Note
in the VSAN that connects these hosts.
Note When persistent FC IDs are enabled, FC IDs cannot be changed after a reboot. FC IDs are enabled by
default, but can be disabled for each VSAN.
A persistent FC ID assigned to an F port can be moved across interfaces and can continue to maintain
the same persistent FC ID.

Enabling the Persistent FC ID Feature

To enable the persistent FC ID feature, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# fcdomain fcid persistent vsan vsan-id
FCID(s) persistent feature is enabled.
switch(config)# no fcdomain fcid persistent vsan
vsan-id

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:
•
•
•
•
OL-16597-01
The current FC IDs in use in the fcdomain are saved across reboots.
The fcdomain automatically populates the database with dynamic entries that the switch has learned
about after a device (host or disk) is plugged into a port interface.
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 VSANs.
Verify that the domain part of the FC ID is the same as the runtime domain ID in the required VSAN.
If the software detects a domain mismatch, the command is rejected.
Verify that the port field of the FC ID is 0 (zero) when configuring an area.
