About Persistent FC IDs

When persistent FC IDs are enabled, the following consequences apply:
•
•
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 FC IDs are enabled by default. This change of default behavior from releases prior to Cisco MDS
SAN-OS Release 2.0(1b) prevents FC IDs from being changed after a reboot. You can disable this option
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.
Note Persistent FC IDs with loop-attached devices (FL ports) need to remain connected to the same port in
which they were configured.
Due to differences in Arbitrated Loop Physical Address (ALPA) support on devices, FC ID persistency
Note
for loop-attached devices is not guaranteed.

Enabling the Persistent FC ID Feature

To enable the persistent FC ID feature using Fabric Manager, follow these steps:
Expand Fabricxx > VSANxx and then select Domain Manager in the Logical Domains pane for the
Step 1
fabric and VSAN that you want to enable the Persistent FC ID feature for.
You see the running configuration of the domain in the Information pane.
Select the Persistent Setup tab and check the enable check box for each switch in the fabric that will
Step 2
have persistent FC ID enabled.
Click the Apply Changes icon to save these changes.

About Persistent FC ID Configuration

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. Follow these requirements to manually configure a persistent FC ID:
•
OL-16184-01, Cisco MDS SAN-OS Release 3.x
The currently in use FC IDs 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.
