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.
