Troubleshooting

231Fabric OS Procedures Version 3.1.x/4.1.x User Guide

1 Gig example:

2 Gig example:

— The sn field indicates a speed negotiation.

— The NC field indicates Negotiation Complete.

— The 01 or 02 fields indicate the speed that has been negotiated.

If these fields do not appear, move on to step 3.

3. Correct the negotiation by entering the portCfgSpeed

[slotnumber/]portnumber, speed_level command if the fields

above do not appear.

Link Initialization Failure (Loop)

1. Verify the port is an L_Port.

a. Enter the switchShow command.

b. Check the comment 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.

2. Verify the loop initialization if the port is not an L_port.

a. Enter the portLogShow or portLogDump command.

b. Check the event area for a loopscn entry with command code BMP.

Example:

The loopscn entry display indicates that the loop initialization is complete.

3. Skip point-to-point initialization.

StorageWorks SAN switches switch the point-to-point initialization after the

Loop Initialization Soft Assigned (LISA) phase of the loop initialization. This

behavior sometimes causes trouble with old HBAs. If this is the case:

— Skip point-to-point initialization by using the portCfgLport

Command.
