Resolving an operating system boot failure

Learn how to identify the service action that is needed to resolve a failure while booting your operating system.

1. Was the system recently installed, serviced, moved, or upgraded?

   If	Then
   Yes:	Ensure that all cables are properly seated in the connection path to the designated boot device. This ends the procedure.
   No:	Continue with the next step.

2. Are you booting the operating system from a network location?

   If	Then
   Yes:	Continue with the next step.
   No:	Continue with step 4.

3. Complete the following actions, one at a time, until the problem is resolved:
   1. Ensure that a problem does not exist with the connection to the network location.
   2. Ensure that the adapter has a valid IP address for the network.
   3. Replace the network adapter.
      • If your system is an 8335-GCA or 8335-GTA, go to 8335-GCA and 8335-GTA locations to identify the physical location and the removal and replacement procedure.
      • If your system is an 8335-GTB, go to 8335-GTB locations to identify the physical location and the removal and replacement procedure.
      • If your system is an 8348-21C, go to 8348-21C locations to identify the physical location and the removal and replacement procedure.
4. Petitboot displays all recognized bootable images to use by default. Is the boot image recognized by Petitboot?

   If	Then
   Yes:	Continue with step 11.
   No:	Select the Petitboot menu option to refresh the boot images. If the problem persists, continue with the next step.

5. Is the system an 8348-21C, and is the boot image on a storage device that is configured in a RAID configuration?

   If	Then
   Yes:	Continue with the next step.
   No:	Continue with step 11.

6. On the Petitboot command line, type the following command:

   arcconf getconfig 1 LD

   Is the logical boot drive recognized and in optimal status?

   If	Then
   Yes:	Reinstall the operating system on the logical drive. This ends the procedure.
   No:	Continue with the next step.

7. Are the drives properly seated in their respective drive bays?
   Note:

   • If your system is an 8335-GCA or 8335-GTA, go to 8335-GCA and 8335-GTA locations to identify the physical location and the removal and replacement procedure.
   • If your system is an 8335-GTB, go to 8335-GTB locations to identify the physical location and the removal and replacement procedure.
   • If your system is an 8348-21C, go to 8348-21C locations to identify the physical location and the removal and replacement procedure.

   If	Then
   Yes:	Continue with the next step.
   No:	Properly seat the drives in the drive bays. Then, go to step 4.

8. Refresh the Petitboot boot options. Is the boot image on the logical drive recognized?

   If	Then
   Yes:	Boot the operating system. Then, continue with step 11.
   No:	Continue with the next step.

9. Verify that the physical drives are in the RAID array. On the Petitboot command line, type the following command:

   arcconf getconfig 1 PD

   Are the physical drives that are known to be in the RAID array recognized?

   If	Then
   Yes:	Reinstall the operating system on the logical drive. This ends the procedure.
   No:	Continue with the next step.

10. Complete the following actions, one at a time, until the physical drives are recognized in the RAID array:
    Note:

    • If your system is an 8335-GCA or 8335-GTA, go to 8335-GCA and 8335-GTA locations to identify the physical location and the removal and replacement procedure.
    • If your system is an 8335-GTB, go to 8335-GTB locations to identify the physical location and the removal and replacement procedure.
    • If your system is an 8348-21C, go to 8348-21C locations to identify the physical location and the removal and replacement procedure.
    1. Ensure that the SAS cable is securely seated in the RAID adapter and the storage backplane.
    2. Replace the RAID adapter.
    3. Replace the SAS cable.
    This ends the procedure.
11. Does an operating system error occur during the boot?

    If	Then
    Yes:	Recover the operating system with the tools provided for the operating system. If that does not resolve the problem, reinstall the operating system. This ends the procedure.
    No:	Reinstall the operating system. This ends the procedure.
