MAP2250 Local/remote switch setting is different between RPC cards

The management console has received an interrupt from an RPC card that shows the Local/Remote Switch setting has changed and the switch setting is now being reported as different between the two RPCs.

About this task

The actual failure could be one of the following:

Scenario 1: The switch setting has been changed, but one of the RPC cards is not reporting the change.
Scenario 2: The switch setting has not been changed, but one of the RPC cards is falsely reporting a change.

Note: When only one RPC card reports a change to the switch setting, the reported change may be true or false. Use this MAP to determine the switch setting.

MAP2250 Section-1

Procedure

Determine and record which RPC card is fenced.

At the upper rear right of Rack-1:
- For Model 941, observe the green LED (left RPC-2 card, C2) and green LED (right RPC-1 card, C1). (Figure 1)
- For Model 951, observe the green LED (left RPC-2 card, C2) and green LED (right RPC-1 card, C1). (Figure 1.)
- For Model 961, observe the green LED (lower RPC-2 card, C2) and green LED (upper RPC-1 card, C1). (Figure 2)

Use Table 1 to continue this repair

MAP2250 Section-2

Procedure

The RPC-1 card (C1) is incorrectly reporting the Local/Remote switch setting. The switch setting is Local and the last setting the management console detected was Local so the failure has caused the RPC-1 card (C1) to incorrectly report the switch setting as Remote. Use the FRU replace option to replace the following FRUs in the order listed. (Refer to MAP1230 Replace a FRU without using a serviceable event.)

RPC-1 (C1) card
Cable between the RPC-1 (C-1) card and LR/ZLR switch card cable. (The cable is not listed as a FRU, instead select the RPC-1 (C1) card when directed to replace it, replace the cable.)
LR/ZLR switch card

MAP2250 Section-3

Procedure

The RPC-2 (C2) card is incorrectly reporting the switch state. The switch setting has been changed to remote but the RPC-2 (C2) card is not reporting the switch change.
Do the following:
1. Change the Local/Remote switch to Local.
2. Use the utility option to System Level Deactivate and then System Level Activate the RPC-1 (C1) card.
  Storage Facility Management > storage facility > Service Utilities > Activate/Deactivate Resources > Show Rack Enclosures > (select rack) > U2xxx.xxx.sssssss-C1 (Rack power Control (RPC) Card, State: available > System Level Deactivate
3. Use the FRU replace option to replace the following FRUs in the order listed. For each FRU being replaced, when fix verification has completed successfully, change the Local/Remote switch setting to Remote. (Refer to MAP1230 Replace a FRU without using a serviceable event.)
  1. RPC-2 (C2) card
  2. Cable between the RPC-2 (C2) card and the LR/ZLR switch card. (The cable is not listed as a FRU, instead select the RPC-2 (C2) card when directed to replace it, replace the cable.)
  3. LR/ZLR switch card
Observe the RPC-1 (C1) card green LED. Is the green LED lit?
- Yes, both RPC cards are operational, the failure has been repaired. Exit this MAP and close the serviceable event.
- No, the original failure has reoccurred. Go to MAP2250 Section-5 step 1 and replace the next FRU in the list.

MAP2250 Section-4

Procedure

The RPC-2 (C2) card is incorrectly reporting the Local/Remote switch setting. The management console is still reporting the switch setting is Remote but the actual switch setting is Local. That indicates the switch setting was changed from Remote to Local and the RPC-2 (C2) card is still reporting a Remote switch setting.
Do the following actions to further isolate the cause of the failure:
1. Change the Local/Remote switch to Remote. This will make the switch setting, as detected by the two RPCs, agree.
2. Use the utility option to System Level Deactivate and then System Level Activate the RPC-1 (C1) card so that the fence is reset and it becomes operational (the green LED is lit).
  Storage Facility Management > storage facility > Service Utilities > Activate/Deactivate Resources > Show Rack Enclosures > (select rack) > U2xxx.xxx.sssssss-C1 (Rack power Control (RPC) Card, State: available > System Level Deactivate
3. Use the utility option to System Level Deactivate the RPC-2 (C2) card
4. Change the Local/Remote switch setting back to Local.
5. Disconnect the cable at J204 on the RPC-2 (C2) card. With the cable disconnected the signal from the switch will be reporting the switch is in the Local position.
6. Use the utilities to System Level Activate the RPC-2 (C2) card.
Observe the RPC-2 (C2) card green LED. Is the green LED lit?
- Yes, go to the next step.
- No, the RPC-2 (C2) card is failing and has been fenced again. Use the replace FRU option to replace the RPC-2 (C2) card. (Refer to MAP1230 Replace a FRU without using a serviceable event.)
Do the following:
1. Disconnect the cable at J2 on the LR/ZLR switch card.
2. Reconnect the cable at J204 on RPC-2 (C2) card.
3. Go to the next step.
Observe the RPC-2 (C2) card green LED.. Is the green LED lit?
- Yes, RPC-2 (C2) card is not fenced, the LR/ZLR card is failing. Use the replace FRU option to replace the LR/ZLR switch card.
- No, RPC-2 (C2) card is fenced again and the cable between RPC-2 (C2) card and the LR/ZLR switch card is failing. Use the replace FRU option to replace the cable. (Refer to MAP1230 Replace a FRU without using a serviceable event.) (The cable is not listed as a FRU, instead select the RPC-2 (C2) card when directed to replace it, replace the cable.)

MAP2250 Section-5

Procedure

The RPC-1 (C1) card is incorrectly reporting a switch setting change to Remote. The switch setting is Remote and the last setting the management console detected was Remote so the failure has caused the RPC-1 (C1) card to incorrectly report the switch setting as Local. The cable between the RPC-1 (C1) card card and the LR/ZLR switch card may be loose or disconnected.
Do the following:
1. Inspect and correct any problems for the cable connector J1 on the LR/ZLR switch card.
2. Inspect and correct any problems for the cable at connector at J204 on the RPC-1 card.
  Was a cable problem found and corrected?
  - Yes, go to the next step.
  - No, go to the next step.
Use the utility option to System Level Deactivate and then System Level Activate the RPC-1 (C1) card.
Storage Facility Management > storage facility > Service Utilities > Activate/Deactivate Resources > Show Rack Enclosures > (select rack) > U2xxx.xxx.sssssss-C1 (Rack power Control (RPC) Card, State: available > System Level Deactivate
- If the System Level Activate is successful, the failure has been repaired. Exit this MAP and close the serviceable event.
- If the System Level Activate fails, go to the next step.
Use the replace FRU option to replace the RPC-1 (C1) card. (Refer to MAP1230 Replace a FRU without using a serviceable event.)
Was the FRU verification successful?
- Yes, exit this MAP and close the original serviceable event.
- No, go to the next step.
Use the replace FRU option to replace the cable between the RPC-1 (C1) card and the LR/ZLR switch card. (Refer to MAP1230 Replace a FRU without using a serviceable event.) (The cable is not listed as a FRU, instead select the RPC-1 (C1) card when directed to replace it, replace the cable.)
Was the FRU verification successful?
- Yes, exit this MAP and close the original serviceable event.
- No, go to the next step.
Change the Local/Remote switch to the Local setting.
Use the replace FRU option to replace the LR/ZLR switch card. When the LR/ZLR switch card replacement is complete, return the Local/Remote switch setting to the Remote setting. When the repair has been completed, exit this MAP and close the serviceable event.

MAP2250 Section-6

Procedure

The RPC-2 (C2) card is incorrectly reporting the Local/Remote switch setting. The switch setting is Local and the last setting the management console detected was Local so the failure has caused the RPC-2 (C2) card to incorrectly report the switch setting as Remote. Use the FRU replace option to replace the following FRUs in the order listed until the failure is resolved. (Refer to MAP1230 Replace a FRU without using a serviceable event.)

RPC-2 (C2) card
