Solution
Disable switch using the switchDisable command.
Enable Access Gateway mode using
the ag modeenable 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 Access Gateway Mode.
On the edge switch, enter the portCfgShow command.
Verify that NPIV status for the port to which Brocade Access Gateway
is connected is ON.
If the status displays as "--" NPIV is disabled. Enter the
portCfgNpivPort <port_number> command with the 1 operand to
enable NPIV.
Repeat step for each port as required.
On Brocade Access Gateway, enter the portCfgShow command.
For each port that is to be activated as an N_Port, enter the
portCfgNport <port_number> command with the 1 operand.
All other ports remain as F_Port.
To reset the port to an F_Port, enter the portCfgNpivPort
<port_number> command with the 0 operand.
Verify zoning on the edge switch.
Verify that F_Ports are mapped to an online N_Port. See
Gateway default F_Port-to-N_Port mapping"
Perform a visual inspection of the cabling, check for issues such as
wrong ports, twisted cable, or bent cable. Replace the cable and try
again.
