MAP 5000: Start

MAP 5000: Start is an entry point to the maintenance analysis procedures (MAPs) for the SAN Volume Controller system.

Before you begin

Note: The service assistant interface should be used if there is no front panel display, for example on the SAN Volume Controller 2145-DH8.

If you are not familiar with these maintenance analysis procedures (MAPs), first read Using the maintenance analysis procedures.

This MAP applies to all SAN Volume Controller models. Be sure that you know which model you are using before you start this procedure. To determine which model you are working with, look for the label that identifies the model type on the front of the node.

You might be sent here for one of the following reasons:

The fix procedures sent you here
A problem occurred during the installation of the SAN Volume Controller system
Another MAP sent you here
A user observed a problem that was not detected by the system

SAN Volume Controller nodes are configured in pairs. While you service one node, you can access all the storage managed by the pair from the other node. With concurrent maintenance, you can remove, replace, and test all FRUs on one SAN Volume Controller system while the SAN and host systems are powered on and doing productive work.

Notes:

Unless you have a particular reason, do not remove the power from both nodes unless instructed to do so.
If an action in these procedures involves removing or replacing a part, use the applicable procedure.
If the problem persists after you complete the actions in this procedure, return to step 1 of the MAP to try again to fix the problem.

(from steps 1, 3, 4, and 5)
Is the power indicator on the front panel off? Check to see whether the power LED on the operator-information panel is off.
NO

Go to step 7.

YES

Try to turn on the nodes. See Using the power control for the SAN Volume Controller node.
Note: The uninterruptible power supply unit that supplies power to the node might also be turned off. The uninterruptible power supply must be turned on before the node is turned on.
SAN Volume Controller 2145-DH8 does not have an external uninterruptible power supply unit. This system has battery modules in its front panel instead.

If the nodes are turned on, go to step 7; otherwise, go to the appropriate Power MAP: MAP 5050: Power 2145-CG8 and 2145-CF8 or MAP 5040: Power SAN Volume Controller 2145-DH8.
(from step 6)
Does the front panel of the node show a hardware error?
NO

Go to step 8.

YES
The service controller for the SAN Volume Controller system failed. (The SAN Volume Controller 2145-DH8 does not have a service controller.)
1. Check that the service controller that is indicating an error is correctly installed. If it is, replace the service controller.
2. Go to MAP 5700: Repair verification.
(from step 7)
Is the operator-information panel error LED ( 1 in Figure 1 or 4 in Figure 2 or 7 in Figure 3) illuminated or flashing? Or, is the check log LED ( 6 in Figure 3) illuminated or flashing?

2. Access the service assistant interface via the Technician port for node access and follow the service recommendation presented.
3. Go to MAP 5700: Repair verification.
(from step 11)
Is Booting displayed on the top line of the front-panel display of the node?
NO

Go to step 14.

YES

Go to step 13.
(from step 12)
A progress bar and a boot code are displayed. If the progress bar does not advance for more than 3 minutes, the progress is stalled.

Has the progress bar stalled?
NO

Go to step 14.

YES
1. Note the failure code and go to Boot code reference to complete the repair actions.
2. Go to MAP 5700: Repair verification.
(from step 12 and step 13)
If you pressed any of the navigation buttons on the front panel, wait for 60 seconds to ensure that the display switched to its default display.

Is Node Error displayed on the top line of the front-panel display of the node?

Or, is the node fault LED, which is the middle of the 3 status LEDs on the front panel of a SAN Volume Controller 2145-DH8, on? Figure 5 shows the node fault LED.
NO

Go to step 15.

YES
Complete these steps:
1. Note the failure code and go to Node error code overview to complete the repair actions.
2. If the node does not have a front panel display, access the service assistant interface via the Technician port for node access and follow the service recommendation presented.
3. Go to MAP 5700: Repair verification.
(from step 14)
Is Cluster Error displayed on the top line of the front-panel display of the node?
NO

Go to step 16.

YES
A cluster error was detected. This error code is displayed on all the operational nodes in the system. The fix procedures normally repair this type of error. Follow these steps:
1. Go to Clustered-system code overview to complete the repair actions.
2. Go to MAP 5700: Repair verification.
(from step 15)
Is Powering Off, Restarting, Shutting Down, or Power Failure displayed in the top line of the front-panel display?

NO

Go to step 18.

YES

The progress bar moves every few seconds. Wait for the operation to complete and then return to step 1 in this MAP. If the progress bar does not move for 3 minutes, press power and go to step 17.
(from step 16)
Did the node power off?
NO
Complete the following steps:
1. Remove the power cord from the rear of the box.
2. Wait 60 seconds.
3. Replace the power cord.
4. If the node does not power on, press power to power on the node and then return to step 1 in this MAP.
YES
Complete the following steps:
1. Wait 60 seconds.
2. Click power to turn on the node and then return to step 1 in this MAP.
Note: The 2145 UPS-1U turns off only when its power button is pressed, input power has been lost for more than five minutes, or the SAN Volume Controller node has shut it down following a reported loss of input power.
(from step 17)
Is Charging or Recovering displayed in the top line of the front-panel display of the node?
NO

Go to step 19.

YES
- If Charging is displayed, the uninterruptible power supply battery is not yet charged sufficiently to support the node. If Charging is displayed for more than 2 hours, go to MAP 5150: 2145 UPS-1U.
- If Recovering is displayed, the uninterruptible power supply battery is not yet charged sufficiently to be able to support the node immediately following a power supply failure. However, if Recovering is displayed, the node can be used normally.
- If Recovering is displayed for more than 2 hours, go to MAP 5150: 2145 UPS-1U.
(from step 18)
Is Validate WWNN? displayed on the front-panel display of the node?
NO

Go to step 20.

YES
The node is indicating that its WWNN might need changing. The node enters this mode when the node service controller or disk is changed but the service procedures were not followed.
Note: Do not validate the WWNN until you read the following information to ensure that you choose the correct value. If you choose an incorrect value, you might find that the SAN zoning for the node is also not correct and more than one node is using the same WWNN. Therefore, it is important to establish the correct WWNN before you continue.
1. Determine which WWNN that you want to use.
  - If the service controller was replaced, the correct value is probably the WWNN that is stored on disk (the disk WWNN).
  - If the disk was replaced, perhaps as part of a frame replacement procedure, but was not reinitialized, the correct value is probably the WWNN that is stored on the service controller (the panel WWNN).
2. Select the stored WWNN that you want this node to use:
  - To use the WWNN that is stored on the disk:
    From the Validate WWNN? panel, press and release the select button. The Disk WWNN: panel is displayed and shows the last five digits of the WWNN that is stored on the disk.
    
    From the Disk WWNN: panel, press and release the down button. The Use Disk WWNN? panel is displayed.
    
    Press and release the select button.
  - To use the WWNN that is stored on the service controller:
    From the Validate WWNN? panel, press and release the select button. The Disk WWNN: panel is displayed.
    
    From the Disk WWNN: panel, press, and release the right button. The Panel WWNN: panel is displayed and shows the last five numbers of the WWNN that is stored on the service controller.
    
    From the Panel WWNN: panel, press and release the down button. The Use Panel WWNN? panel is displayed.
    
    Press and release the select button.
3. After you set the WWNN, check the front-panel display:
  - If the Node WWNN: panel is displayed on the front panel, the node is now using the selected WWNN. The Node WWNN: panel shows the last five numbers of the WWNN that you selected.
  - If the front panel shows Cluster: but does not show a system name, you must use the recover procedure for a clustered system to delete the node from the system and add the node back into the system.
(from step 19)
Is there a node that is not a member of a clustered system? You can tell if a node is not a member of a system because the node status LED is off or blinking for SAN Volume Controller 2145-DH8 or by checking the front-panel menu. If Cluster: is displayed but no system name is shown, the node is not a member of a system. If the current language font allows a two-line display, the name is on the second line of the front-panel display. Otherwise, you can press the select button to display the name.)

NO

Go to step 21.

YES

The node is not a member of a system. The node might have been deleted during a maintenance procedure and was not added back into the system. Make sure that each I/O group in the system contains two nodes. If an I/O group has only one node, add the node back into that system. Then, ensure that the node is restored to the same I/O group from which it was deleted.
(from step 20)
Is the front-panel display unreadable?
NO

Go to step 22.

YES
Complete the following steps:
1. Check the language. The display might be set to another language.
2. If the language is set correctly, go to MAP 5400: Front panel.
(from step 21)
No errors were detected by the SAN Volume Controller system. If you suspect that the problem that is reported by the customer is a hardware problem, follow these tasks:
1. Complete Problem Determination procedures on your host systems, disk controllers, and Fibre Channel switches.
2. Ask IBM remote technical support for assistance.
(from step 10)
Can you access the service assistant interface through the 2145-DH8 technician port or service IP address, or use a USB flash drive to get satask_results.html?

NO

The SAN Volume Controller software might not be running. Attach a USB keyboard and VGA monitor to the 2145-DH8 to see if the node is stuck booting.

YES

Go to step 24.
(from step 23)
Can node error 561 be seen?

NO

Follow the recommended action for any node error that can be seen.

YES

The SAN Volume Controller software might not be able to communicate with the battery backplane.

Check the connections between the system board and the battery backplane. Then follow the recommended action for node error 561.

Results

If you suspect that the problem is a software problem, see "Updating the system" documentation for details about how to update your entire SAN Volume Controller environment.

If the problem is still not fixed, collect diagnostic information and contact IBM® Remote Technical Support.
