Goal

Limitations and restrictions of Virtual Fabrics

All logical switches in a fabric should have the same base switch attribute. If a base switch is connected to a non-base switch, then you must take the appropriate action to resolve the conflict.

The following platforms are Virtual Fabrics-capable:
• Brocade 5100
• Brocade 5300
• Brocade 6510
• Brocade 6520
• Brocade 7800
• Brocade VA-40FC, in Native mode only
• Brocade DCX
• Brocade DCX-4S
• Brocade DCX 8510 family

Solution

Please refer to:

Brocade Fabric OS Administrator’s Guide -- Chapter 11: Limitations and restrictions of Virtual Fabrics

https://www.brocade.com/downloads/documents/product_manuals/B_SAN/FOS_AdminGd_v720.pdf

If you move existing EX_Ports or VEX_Ports to any logical switch other than the base switch,
these ports are automatically disabled

Base switch issues

All logical switches in a fabric should have the same base switch attribute. If a base switch is connected to a non-base switch,
then you must take the appropriate action to resolve the conflict.

Symptom :

EX_Port is disabled with reason "Export in non base switch".

Probable cause and recommended action

An EX_Port must be in the base switch.

Use the lsCfg --create command with the -b option to create a base switch.
Then use the lsCfg --config command with the -slot and -port options to move the port to the base switch. If the port is not intended to be used as an EX_Port, use the portCfgDefault command to reset the port to its default configuration.
