You can follow these workarounds to complete the unroot process. 
 

Workaround 1

  1. If /etc/vx/rootdisk_info.machine_name is misplaced, restore it.
     
  2. Reinitiate vxunroot.

Workaround 2 (If you cannot restore /etc/vx/rootdisk_info.machine_name)

  1. If rootdisk is mirrored, do the following in the order listed. Otherwise, go to step 2.

    • Detach the mirror disk.
       
    • Change the Universally Unique Identifier (UUID) of partitions on the mirror disk. Enter:

      tune2fs -U UUID device_name
  1. Confirm that the root device entry in /boot/grub/menu.lst.b4vxvm is correct.    In case of the UUID, you can confirm that it points to right device. Enter:

    $ vxgetdev -U UUID
  1. Restore the original menu.lst file by coping it from menu.lst.b4vxvm. Enter:

    cp /boot/grub/menu.lst.b4vxvm /boot/grub/menu.lst
  1. Confirm that the device entries in /etc/fstab.b4vxvm are correct. In the case of the UUID, you can confirm that it points to the right device. Enter:

    $ vxgetdev -U UUID
  1. Restore the original fstab file by coping it from /etc/fstab.b4vxvm. Enter:

    cp /etc/fstab.b4vxvm /etc/fstab
  1. Make sure that the kernel entry and the initrd names are valid in the system. Also verify that  the kernel command line options are valid with the kernel image.
     
  2. Remove partitions of root disk which have ID 7f or 7e. Typically, those will be of type unknown. For example:

    Device Boot          Start         End      Blocks   Id  System
                  /dev/sda1   *               1       35650    286358593+  83  Linux
                  /dev/sda2           35651       36399     6016342+  82  Linux swap / Solaris
                  /dev/sda3           36400       36404     40162+  7f  Unknown
     
  3. Reboot the computer.
     
  4. After the reboot, you may remove the following files:

    • /boot/VxVM_Initrd.img
       
    • /boot/grub/menu.list.b4vxvm
       
    • /etc/fstab.b4vxvm
