From the switch supportshow file:

The output shows the switch has all ports belonging to the default logical switch (FID=128); except for port 9 which is the base logical switch (FID=8).

lscfg --show :Created switches FIDs(Domain IDs): 128(ds)(1) 8(bs)(1)Port 0 1 2 3 4 5 6 7 8 9-------------------------------------------------------------------FID 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 8 |Port 10 11 12 13 14 15 16 17 18 19-------------------------------------------------------------------FID 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 |Port 20 21 22 23 24 25 26 27 28 29-------------------------------------------------------------------FID 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 |Port 30 31 32 33 34 35 36 37 38 39-------------------------------------------------------------------FID 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 | 128 |

NOTE:
A. Save a copy of the current physical switch configuration:

    configupload
    supportsave

B. Save the configuration of the base logical switch:

  fosexec --fid 8 -cmd "supportsave"
  fosexec --fid 8 -cmd "configupload"

Disabling Virtual Fabrics mode

Use the following procedure to disable Virtual Fabrics mode:
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

FC Routing service:             enabled
iSCSI service:                  Service not supported on this Platform
iSNS client service:            Service not supported on this Platform
Virtual Fabric:                 enabled
Ethernet Switch Service:        Service not supported on this Platform

3. Move all ports to the default logical switch.

lscfg --config 128 -port 9

4. Delete all of the non-default logical switches.

lscfg --delete 8

5. Use the fosConfig command to disable VF mode:

fosconfig --disable vf
