About FICON Device Allegiance
FICON requires serialization of access among multiple mainframes, CLI, and SNMP sessions be
maintained on Cisco MDS 9000 Family switches by controlling device allegiance for the currently
executing session. Any other session is denied permission to perform configuration changes unless the
required allegiance is available.
This task discards the currently executing session.
Caution
Clearing FICON Device Allegiance
You can clear the current device allegiance by issuing the clear ficon vsan vsan-id allegiance command
in EXEC mode.
switch# clear ficon vsan 1 allegiance
