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.
