Resolving an operating system boot failure

Learn how to identify the service action that is needed to resolve a failure while you boot the 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. To identify the physical location and the removal and replacement procedure, see 7063-CR1 locations.
4. Petitboot displays all recognized bootable images to use by default. Is the boot image recognized by Petitboot?

   If	Then
   Yes:	Continue with step 15.
   No:	Select the Petitboot menu option to refresh boot images. If the problem persists, continue with the next step.

5. From the Petitboot menu, select Exit to shell. Is the mvcli utility already installed?

   If	Then
   Yes:	Continue with step 7.
   No:	Continue with the next step.

6. Install the mvcli utility. For more information about installing the mvcli utility, go to mvCLI commands. Then, continue with the next step.
7. If you obtained the mvcli utility from a USB drive that is inserted into one of the USB ports of the system, type /tmp/media/mvcli. Otherwise, type /tmp/mvcli.
8. To check the status of the RAID virtual disk, type info -o vd and press Enter. To check the status of the physical disks, type info -o pd and press Enter. The output indicates the status of the drive.
   Is the boot drive recognized and in optimal status?

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

9. Are the drives properly seated in their respective drive bays?
   Note: To identify the physical location and the removal and replacement procedure, see 7063-CR1 locations.

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

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

    If	Then
    Yes:	Boot the operating system. Then, continue with step 15.
    No:	Continue with the next step.

11. From the Petitboot menu, select Exit to shell.
12. If you obtained the mvcli utility from a USB drive that is inserted into one of the USB ports of the system, type /tmp/media/mvcli. Otherwise, type /tmp/mvcli.
13. To check the status of the RAID virtual disk, type info -o vd and press Enter. To check the status of the physical disks, type info -o pd and press Enter. The output indicates the status of the drive.
    Are the drives that are known to be in the virtual drive recognized?

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

14. Complete the following actions, one at a time until the physical drives are recognized in the virtual drive:
    Note: To identify the physical location and the removal and replacement procedure, see 7063-CR1 locations.

    1. If the drive is connected directly to the system backplane, ensure that the SATA cables are properly seated in the disk drive backplane and in the system backplane.
    2. Replace the SATA cable.
    3. If the drive is connected directly to the system backplane, replace the system backplane.

    This ends the procedure.
15. Does an operating system error occur during the boot?

    If	Then
    Yes:	Recover the operating system by using the tools 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.
