7. Unencapsulating Your Root Disk

There are two methods for this. The preferable choice is to use the command "vxunroot". If you can't do this for some reason, or you need to repair a system that has crashed, you can manually un-encapsulate the disk using the following steps:

1) Boot off the cdrom
     # boot cdrom -sw

2) Mount the root file system.  Your root slice could be different. 
     # mount /dev/dsk/c0t0d0s0 /a

3) Edit /a/etc/system
     Using "*" comment out the lines between VXVM BEGIN and VXVM END
     NOTE: There might be a file /a/etc/system.prevm
           That could be used.  The lines look like the following:
            *set vxio:vol_rootdev_is_volume=1

4) Edit /a/etc/vfstab
     Need to comment out the line that references the Volume Manager volumes.
     NOTE: There might be a file /a/etc/vfstab.prevm

4a) Using the information in the vfstab file change the root device to system 
      root disk.  ie. 
      /dev/dsk/c0t0d0s0   /dev/rdsk/c0t0d0s0  /  ufs  1  no   -

      There are lines within the vfstab starting with "NOTE:" that
      indicates the original boot device.  Use this information to recreate the
      original vfstab file.
      There are line similar to this:

     #NOTE: volume rootvol (/) encapsulated partition c0t0d0s0 

    4b) Do the same thing for the other encapsulated volumes (ie. /usr , /opt,

5) Unmount /a, and reboot.
