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.

volencap(8) System Manager's Manual volencap(8)NAME
volencap, volreconfig - Encapsulates disks, partitions, or AdvFS domains
SYNOPSIS
/usr/sbin/volencap [-g diskgroup] [-p volprefix] [privlen=nn] [nconfig=nn] { diskname | partition_name | domain_name }...
/usr/sbin/volencap -k { diskname | partition_name | domain_name }...
/usr/sbin/volencap -k-a
/usr/sbin/volencap -s
/sbin/volreconfig
OPTIONS
Puts the encapsulated disk into the disk group specified by disk group ID or disk group name. Instructs volencap to use the specified vol-
prefix as the prefix for LSM volume names generated. This is useful if the LSM volume names generated already exist. Instructs volencap to
remove any pending encapsulation requests for the specified disk(s), partition(s), or domain(s). Instructs volencap to remove all pending
encapsulation requests. Displays all pending encapsulation requests.
DESCRIPTION
Disk partitions that have data can be added to LSM using the encapsulation process. This enables users with existing data in disk parti-
tions to easily migrate to the use of LSM volumes instead of disk partitions.
The /usr/sbin/volencap command is used to encapsulate one or many disk partitions or AdvFS domains.
If an individual partition is specified for encapsulation, the volencap command creates a nopriv disk and a volume for that partition.
If an entire disk is specified, the volencap command creates a nopriv disk and volume for each in-use partition on the disk.
If an AdvFS domain is specified, all disk partitions in the domain are converted to LSM volumes.
You can use the volencap command to encapsulate the partitions on the boot disk, including the root file system, primary swap, usr and var
partitions, to place them under LSM control. See the Logical Storage Manager manual for more information on encapsulating these partitions.
The volencap command can be run directly or through the voldiskadm menus. The volencap command generates LSM commands that are later exe-
cuted by the /sbin/volreconfig command to perform the actual conversion of disk partitions to LSM volumes.
If the disk partition contains a mounted file system or is otherwise open or in use, the volreconfig command will reboot the system to com-
plete the encapsulation process. If you cannot reboot the system at the time you encapsulate the disk partition, either defer running the
volreconfig command until you can reboot the system, or unmount or close the disk partition, then run the volreconfig command.
See the Logical Storage Manager manual for more details.
ATTRIBUTES
Specifies the size of the LSM private region in bytes, for example, privlen=1024. Specifies the number of log copies and copies of the
configuration database, for example, nconfig=0.
EXAMPLES
To encapsulate all disk partitions on the boot disk called dsk0 to LSM volumes, enter: # volencap dsk0 # volreconfig
The volreconfig command will request confirmation prior to rebooting the system. The LSM command scripts created by the volencap
command will execute as the system reboots. To encapsulate only the root file system (dsk0a) and swap (dsk0b) partitions on the
boot disk, enter: # volencap dsk0a dsk0b # volreconfig
The volreconfig command will request confirmation prior to rebooting the system. The LSM command scripts created by the volencap
command will execute as the system reboots. To convert all disk partitions in the AdvFS domain called dom1 to LSM volumes, enter: #
volencap dom1 # volreconfig
The volreconfig command will determine if the domain is active, and if so, request confirmation prior to rebooting the system. The
LSM command scripts created by the volencap command will execute as the system reboots.
If the AdvFS filesets in domain dom1 are not mounted, then /sbin/volreconfig can be executed on the command line. To encapsulate
the specific partition dsk1g to an LSM volume, enter: # volencap dsk1g # volreconfig
The volreconfig command will determine if the partition is open, and if so, request confirmation prior to rebooting the system. The
LSM command scripts created by the volencap command will be executed as the system reboots.
