Troubleshooting the SLSA Subsystem

GESA: Gigabit Ethernet Adapter Installation and Support Guide●

For Token-Ring ServerNet Adapters (TRSAs):

Cause: The Token-Ring cable is faulty, is not connected to an operational hub, or is not connected to the

adapter.

Recovery: Make sure the cable is operational and is connected to the adapter. Replace or reconnect the

cable, as required. Make sure the hub is operational and replace it, as required.

Cause: The LAN speed does not match the ring speed of the physical interface (PIF).

Recovery: Make sure the LAN speed matches the ring speed configured for the PIF. To display the ring

speed for a PIF, use the SCF INFO PIF command:

INFO PIF $ZZLAN.<adapter>.<sac>.<pif>, DETAIL

The example shows the output of this command.

To alter the ring speed for a PIF, do the following:

1 Stop the PIF.

Use the SCF STOP PIF command:

STOP PIF $ZZLAN.<adapter>.<sac>.<pif>

2 Alter the ring speed for the PIF.

Use the SCF ALTER PIF command:

ALTER PIF $ZZLAN.<adapter>.<sac>.<pif>,

RINGSPEED 4

3 Restart the PIF.

Use the SCF START PIF command:

START PIF $ZZLAN.<adapter>.<sac>.<pif>

Cause: The MAC address of the physical interface (PIF) supported by the SAC conflicts with the MAC

address of another PIF on the network.

Recovery: Alter the MAC address for the PIF by performing the following steps.
