If a Fabric OS switch is in AG mode and is also set to McDATA Fabric mode, when that switch is
connected to an M-EOS switch, the Fabric OS switch does not display in the output when you run the
agshow command.
Failover is not working Failover disabled on N_Port. Verify that the failover and failback policies are enabled, as follows:
Enter the ag
--failoverShow command with the port_number
operand.
Enter the ag
--failbackShow command with the port_number
operand.
Command returns “Failback (or Failover) on N_Port port_number is
supported.”
If it returns, “Failback (or Failover) on N_Port port_number is not
supported.” See “F_Ports automatically fail over to any available
N_Port. Alternatively, you can specify a preferred secondary N_Port in
case the primary N_Port fails. If the primary N_Port goes offline, the
F_Ports fail over to the preferred secondary N_Port (if it is online),
then re-enable. If the secondary N_Port is offline, the F_Ports will
disable. Define the preferred secondary N_Ports per F_Port. For
example, if two F_Ports are mapped to a primary N_Port 1, you can
define a secondary N_Port for one of those F_Ports and not define a
secondary N_Port for the other F_Port. F_Ports must have a primary
N_Port mapped before a secondary N_Port can be configured.” on
page 45.
Access Gateway is mode
not wanted
Access Gateway must be disabled. Disable switch using the switchDisable command.
Disable Access Gateway mode using
the ag
--modeDisable command.
Answer yes when prompted; the switch reboots.
Log in to the switch.
Display the switch settings using the switchShow command. Verify
that the field switchMode displays Fabric OS Native mode.
“Login Rejected by FC
stack” messages on
console may be seen
during F_Port and N_Port
disruptions on Brocade
8000 in AG Mode.
The CNA host is retrying a log in before
the switch has finished precessing a
previous fabric logout (LOGO) attempt.
Working as designed. After the switch has completed LOGO
processing, it will accept another login.
