MAP 5900: Hardware boot

MAP 5900: Hardware boot helps you solve problems that are preventing the node from starting its boot sequence.

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 have been sent here for one of the following reasons:

The hardware boot display, shown in Figure 1, is displayed continuously.

Perform the following steps to allow the node to start its boot sequence:

Is this a SAN Volume Controller 2145-8A4 or SAN Volume Controller 2145-4F2?

NO

Go to step 2.

YES

Go to step 3.
(From step 1)
Is the Error LED on the operator-information panel illuminated or flashing?
NO

Go to step 3.

YES

Go to MAP 5800: Light path to resolve the problem.
(From steps 1 and 2)
If you have just installed the SAN Volume Controller node or have just replaced a field replaceable unit (FRU) inside the node, perform the following steps:
1. For a SAN Volume Controller 2145-8A4 node, ensure that the correct power cable assembly from the 2145 UPS-1U to the node is installed. The correct power cable assembly has red tape that binds the cables together.
2. For other SAN Volume Controller models, or if the error LED is still illuminated or flashing, turn off the node. See MAP 5350: Powering off a SAN Volume Controller node.
3. If the error LED is still illuminated or flashing, turn off the node. See MAP 5350: Powering off a SAN Volume Controller node.
4. Identify and label all the cables that are attached to the node so they can be replaced in the same port. Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
5. Remove the top cover. See Removing the top cover.
6. If you have just replaced a FRU, ensure that the FRU is correctly placed and that all connections to the FRU are secure.
7. Ensure that all memory modules are correctly installed and that the latches are fully closed. See Replacing the memory modules (DIMM).
8. Ensure that the fibre-channel adapter cards are correctly installed. See Replacing the fibre-channel adapter assembly.
9. Ensure that the disk drive and its connectors are correctly installed. See Replacing the disk drive.
10. Ensure that the service controller is correctly installed. See Replacing the service controller.
11. If it is not a SAN Volume Controller 2145-4F2, ensure the operator-information panel cable is correctly installed on the system board.
12. Ensure the operator-information panel cable is correctly installed on the system board.
13. Replace the top cover. See Replacing the top cover.
14. Place the node in the rack. See Replacing the SAN Volume Controller in a rack.
15. Turn on the node.
Does the boot operation still hang?
NO

Verify the repair by continuing with MAP 5700: Repair verification.

YES

Go to step 4.
(from step 3)
Check if the system BIOS is reporting any errors. You need to attach a display and keyboard to see the BIOS output. The customer should be able to supply a suitable display and keyboard. If this is a SAN Volume Controller 2145-4F2, you need a special cable to connect the display and keyboard. If you do not have this cable, go to the next step.
1. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node.
2. Connect the keyboard 1 and the display 2 . Figure 3 shows the location of the keyboard and monitor ports. Figure 4 shows the location of the keyboard and monitor ports on the 2145-CF8.

3. Turn on the node.
4. Watch the display.
  - If the POST sequence indicates an error, or if the BIOS Configuration/Setup Utility program indicates an error during startup, you need to resolve the error.
  - If it indicates an error with a specific hardware item, power off the node and remove it from the rack. Ensure the item specified is correctly installed, replace the node, and then restart the node. If the error is still reported, replace the specified item.
  - If a configuration error is reported, run the Configuration/Setup Utility program option to reset the BIOS to its default (factory) settings.
5. Turn off the node and remove the keyboard and display.
6. Turn on the node.
Does the boot operation still hang?
NO

Verify the repair by continuing with MAP 5700: Repair verification.

YES

Go to step 5.
(from step 4)
1. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node.
2. Identify and label all the cables that are attached to the node so they can be replaced in the same port. Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
3. Remove the top cover. See Removing the top cover.
4. Remove some of the memory modules:
  - If you are using the SAN Volume Controller 2145-CF8, remove the memory modules in slots 2, 5, 7, and 8.
  - If you are using the SAN Volume Controller 2145-8A4, remove the memory modules in slots 2 through 4.
  - If you are using the SAN Volume Controller 2145-8G4, remove the memory modules in slots 2 and 4 through 8.
  - If you are using the SAN Volume Controller 2145-8F4 or the SAN Volume Controller 2145-8F2, remove the memory modules in slots 3 through 8.
  - If you are using the SAN Volume Controller 2145-4F2, remove all memory modules in Bank 1.
5. Remove all installed fibre-channel cards.
6. Remove the disk drive.
7. Replace the top cover. See Replacing the top cover.
8. Place the node in the rack. See Replacing the SAN Volume Controller in a rack.
9. Turn on the node.
Does the boot operation still hang with the booting display or is Booting 100 displayed on the front panel?
Note: With the FRUs removed, the boot will hang with a different boot failure code.

NO

Replace the FRUs, one-at-a-time, until the failing FRU is isolated.

YES
