Troubleshooting
A
NOTE
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.”

Access Gateway is mode

Disable Access Gateway mode using
the ag
--

Answer yes when prompted; the switch reboots.
Log in to the switch.

“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.
