MAP1200 Prioritizing serviceable events and visual symptoms for repair

Use this procedure if there is more than one serviceable event and/or visual symptom needing repair.

MAP1200 Section-1

Procedure

Display the details of each problem and then use Table 1 to prioritize their repair.

Table 1. Prioritizing Repairs
Priority	Condition	Description
1	Problems found during an LIC code update process	The LIC code update process checks for code update errors as well as other serviceable events that occur during the process. If any are found, a new serviceable event is created that will guide the repair process by calling a MAP4Axx isolation procedure.
2	CEC enclosure serviceable events	Both CEC enclosures need to be error free before repairing I/O enclosure or storage enclosure problems. This allows FRU verification FC-AL loop verify tests to complete properly.
3	The CEC enclosure control panel is not updating and is displaying a 2-character (xx) or 8-character (xxxxxxxx) code.	Go to MAP4360 Codes displayed by the CEC enclosure control panel.
4	The CEC enclosure control panel is not updating and is displaying something other than a 2-character (xx) or 8-character (xxxxxxxx) code.	Go to MAP4370 CEC enclosure control panel does not show a normal display.
5	I/O enclosure serviceable events	Both CEC enclosures need to be error free to do this repair. I/O enclosures need to be error free before repairing storage enclosure problems. This allows FRU verification FC-AL loop verify tests to complete properly.
6	FC-AL serviceable events	FC-AL loops problems should be repaired before storage enclosure DDM problems. The FRUs for the FC-AL loop are Device Adapter card, the FC-AL cable and the FC-IC card. It is possible but not likely for a DDM to cause an FC-AL loop problem. Note: All CEC and I/O enclosures must be error free. This allows FRU verification FC-AL loop verify tests to complete properly.
7	Storage enclosure serviceable events	Storage enclosure serviceable events are for the FCIC or storage enclosure backplane. The DDMs are listed in the next row in this table.
8	Sorage enclosure DDM serviceable events	Storage enclosure DDM problems can be repaired anytime. After the DDM has been replaced, the DDM certify process, which can take a long time, will run in the background so the service representative does not have to wait for it to finish.
9	Rack power and cooling system serviceable events	Power problems are normally be repaired after logic problems because of the fault tolerant design of the power system.
10	Multiple serviceable events for one fault	A single fault may create more than one related problem. The successful repair of one problem should close all related serviceable events.
11	Visual symptoms	Visual symptoms should create a related serviceable event. Repair related serviceable events before using visual symptoms. If there are no related serviceable events, go to MAP1320 Isolating problems using visual symptoms.
