NOTE
A new option "Disable FID check" has been added to configure fabric parameter options. This can
be used to disable FID check for FICON logical switches.
Fabric identification issues
Symptom E_Ports directly connecting two logical switches does not form or is disabled.
Probable cause and recommended action
The FIDs on each of the logical switches must be the same.
Use the lsCfg
change FID -newfid FID command to change the FID.
--
Symptom Invalid FID.
Probable cause and recommended action
FIDs for switches may be from 1 through 128 as long as they are not already in use, except
EX_Ports which are only assigned FIDs from 1 through 127.
Use the lsCfg
Symptom The FID is currently in use.
Probable cause and recommended action
You may not create two (2) or more logical switches with the same FID.
Use the lsCfg

Logical Fabric issues

Symptom Logical port <port_number> disabled.
Probable cause and recommended action
This message indicates an LISL was disabled due to some protocol conflict or security or policy
violation. This can result in possible traffic issues. You should resolve the cause of the conflict and
re-enable the LISL using the lfCfg

VE_Ports cannot exist in a logical switch that has XISL use turned on. Although VE_Ports are
allowed in a base switch, Fabric OS v6.2.0 and later do not support the use of VE_Ports to
carry traffic for logical fabrics using XISLs. They can be used to carry FCR traffic through EX_
and VEX_Ports. You should make sure your configuration does not result in the use of VE_Ports
in a base switch for logical fabric traffic.
Admin Domains are mutually exclusive with Virtual Fabrics. When Virtual Fabrics is enabled, all
access control is based on the Virtual Fabric context.
Traffic Isolation zones with no-failover option are not supported in logical fabrics. TI zones
defined in the base fabric for logical fabric traffic must allow failover.
