volunroot

volunroot(8)						      System Manager's Manual						      volunroot(8)

NAME

       volunroot - Remove Logical Storage Manager hooks for rootable volumes

SYNOPSIS

       /usr/sbin/volunroot [-a	| -A]

OPTIONS

       Specifies  that	all  volumes on the system disk be converted back to UNIX disk partitions, not just the root and swap volumes, rootvol and
       swapvol.  Forces removal of the private region unless it is the last one in the system.

DESCRIPTION

       The volunroot script can be used to restore the accessibility of the root, swap, and other file systems on the boot disk  directly  through
       disk  partitions  instead  of  through volume devices. The script also removes other changes that were made to enable booting of the system
       from the root volume, so that the system will boot with no dependency on the Logical Storage Manager.

       When used with no options, volunroot affects only the root and swap volumes, rootvol and swapvol.

       For volunroot to work properly, only one plex must exist for each of the affected volumes. This plex must be the one created by	volrootmir
       or the original plex created when the root disk was encapsulated. This ensures that the underlying subdisks will have equivalent partitions
       defined for them on the disk.

       If these conditions are not met, the volunroot operation fails and none of the volumes are converted to disk partitions.

       The unwanted plexes can be removed using either voledit or volplex.
