volsave - Saves a Logical Storage Manager (LSM) configuration
/usr/sbin/volsave [-d dir]
Directs the backup information to the directory specified
by dir. This directory must not already exist.
You can save the LSM configuration records for a disk
group by saving the output of the volprint(8) utility in a
description file that the volmake(8) utility can use. The
volsave command provides an easy way to save this configuration
information for all disk groups. In addition, volsave
saves a list of the disks that are under LSM control
and their attributes. The LSM configuration can be
restored using the volrestore command.
The volsave command creates an LSM description set that
consists of a header file and other files containing
information about the LSM configuration. Refer to the
FILES section for details on the contents of these files.
By default, the description set is saved to a timestamped
directory in /usr/var/lsm/db (for example,
The -d option can be used with volsave to specify a particular
directory for the saved configuration. In this
case, the -d option must also be used with volrestore when
restoring the configuration.
You may receive the following error message when using the
-d dir option with the volsave command: Directory dir
This message indicates that the directory you specified
is already in use. The LSM configuration can
only be saved to a directory that does not yet
exist. You can specify a new directory name, or
enter the volsave command without the -d option and
let volsave create a new, timestamped directory in
Default directory in which volsave creates the timestamped
subdirectories with LSM description sets. Timestamped
subdirectory containing LSM description sets (the header,
voldisk.list, and volboot files). Also contains subdirectories
for each disk group, named diskgroup.d; for example,
rootdg.d. Description file that can be used by the
volmake command for all volumes, plexes, and subdisks in a
disk group. There is one file for each disk group, stored
in the diskgroup.d subdirectory. A description of the
disks. This file is the output of the voldisk list command.
A description of the disk group based on information
from the voldg list diskgroup command. There is one
file for each disk group, stored in the diskgroup.d subdirectory.
Saved copy of the /etc/vol/volboot file. File
containing the checksum, a magic number, the date of the
file's creation, and the version of the volsave command,
that volrestore validates before executing.
