184 Managing virtual fabrics
Enabling Virtual Fabrics
Virtual Fabrics is disabled by default on switches that you upgrade to Fabric OS 6.2.0 or later. Virtual
Fabrics is enabled by default on a new chassis. Before you can use the Virtual Fabrics features, such as
Logical Switch and Logical Fabric, you must enable Virtual Fabrics.
NOTE: When you enable Virtual Fabrics, the CPs are rebooted and all EX_Ports are disabled after the
reboot.
1. Connect to the physical chassis and log in using an account assigned to the admin role with the
chassis-role permission.
2. Enter the following command to check whether Virtual Fabrics is enabled:
fosconfig --show
3. Delete all Admin Domains, as described in ”Deleting all user-defined Admin Domains” on page 206.
4. Enter the following command to enable Virtual Fabrics:
fosconfig --enable vf
5. Enter y at the prompt.
The following example checks whether Virtual Fabrics is enabled or disabled and then enables it.
