Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 285)

• VE_Ports on the FX8-24 blade can be moved to any logical switch independent of the location of the
physical GE port.
• If you move existing EX_Ports or VEX_Ports to any logical switch other than the base switch, these
ports are automatically disabled.
Enabling Virtual Fabrics mode
A fabric is said to be in Virtual Fabrics mode (VF mode) when the Virtual Fabrics feature is enabled.
Before you can use the Virtual Fabrics features, such as logical switch and logical fabric, you must
enable VF mode.
VF mode is enabled by default.
NOTE
When you enable VF mode, the control processors (CPs) are rebooted and all EX_Ports are disabled
after the reboot.
1. Connect to the physical chassis and log in using an account with the chassis-role permission.
2. Use the fosConfig command to check whether VF mode is enabled:
fosconfig --show
3. Delete all Admin Domains, as described in Deleting all user-defined Admin Domains non-disruptively
on page 478.
4. Use the fosConfig command to enable VF mode:
fosconfig --enable vf
5. Enter y at the prompt.
The following example checks whether VF mode is enabled or disabled and then
enables it.
switch:admin> fosconfig --show
FC Routing service: disabled
iSCSI service: Service not supported on this Platform
iSNS client service: Service not supported on this Platform
Virtual Fabric: disabled
Ethernet Switch Service: Service not supported on this Platform
