		SP Switch function (MAP 0620)
Table 1-7. SP Switch error conditions
Error #	Message/condition	Description and action
2	Initialized	Description: Initialization detected a wrapped port where a
(SPS)		processor node or dependent node was expected (this may
		result from isolation procedures), or else a disconnected cable.
		Action:
		1. If this is an unexpected condition, check cabling against
		the configuration file var/adm/SPlogs/css/out.top.
		2. If the processor node or dependent node can be
		reconnected, remove the wrap plug and connect the data
		cable between the switch assembly and the processor node
		or dependent node.
		3. If the processor node or dependent node is to be
		permanently removed, have the customer update the
		switch topology.
		4. Repeat ªStep 0620-001º on page 1-17 for next problem or
		go to ªStep 0620-043º on page 1-36 to verify fix.
	Link status: Operational	Description: Link status is operational.
1		Action: Repeat ªStep 0620-001º on page 1-17 for next problem
(SPS)
		or go to ªStep 0620-043º on page 1-36 to verify fix.
0	Uninitialized	Description: Switch adapter has not been initialized. Processor
(SPS)		node may not recognize adapter due to hardware failure or bad
		software configuration.
		Action:
		1. If there are any other errors in the
		/var/adm/SPlogs/css/out.top file, address those errors first.
		Note: If the problem is on all nodes in the frame, check for
		any hardware problems with the SP Switch. Also check for
		switch-to-switch problems on all jacks of the SP Switch.
		2. If all the nodes are uninitialized except for the primary node,
		verify that the primary node is connected to the correct port.
		3. Have customer verify that the correct switch software is
		installed and running on this node. rc.switch or
		css_restart_node starts the
		fault_service_Worm_RTG_SP daemon and the
		fs_monitor daemon.
		4. Log into processor node and enter:
		lscfg grep css
		5. If you get no result, try swapping in another switch
		adapter. Repeat step 3. If you get a result, the problem is
		probably resolved; repeat ªStep 0620-001º on page 1-17 for
		next problem or go to ªStep 0620-043º on page 1-36 to
		verify fix.
		6. The problem is probably the SP Switch. Go to ªStep
		0620-004º on page 1-21.
	Device status: Device not	Description: Possible hardware problem.
−1	responding	Action: Go to ªStep 0620-004º on page 1-21.
(SPS)
	Link status: Link as been removed
	from network, other stage faulty
−2	Link status: Wrap plug is installed	Description: Initialization detected a wrap plug or cable rather
(SPS)		than the expected cabling.
		Action: Repeat ªStep 0620-001º on page 1-17 for next problem
		or go to ªStep 0620-043º on page 1-36 to verify fix.
