Checking For A Loop Initialization Failure; Checking For A Point-To-Point Initialization Failure - Brocade Communications Systems StoreFabric SN6500B Troubleshooting Manual

Checking for a loop initialization failure

1. Verify the port is an L_Port.
2. Verify that loop initialization occurred if the port to which the loop device is attached does not
3. Skip point-to-point initialization by using the portCfgLport command.

Checking for a point-to-point initialization failure

1. Enter the switchShow command to confirm that the port is active and has a module that is
2. Enter the portLogShow or portLogDump commands.
3. Verify the event area for the port state entry is pstate. The command entry AC indicates that
4. Skip over the loop initialization phase.

a. Enter the switchShow command.
b. Check the last field of the output to verify that the switch port indicates an L_Port. If a loop
device is connected to the switch, the switch port must be initialized as an L_Port.
c. Check to ensure that the state is online; otherwise, check for link failures.

negotiate as an L_Port.
a. Enter the portLogShow or portLogDump command to display the port log for all ports on
the switch; or if you are looking for a specific port, enter the portLogDumpPort command.
b. Check argument number four for the loop initialization soft assigned (LISA) frame

This behavior sometimes causes trouble with old HBAs.
