lsmbstartup(8) System Manager's Manual lsmbstartup(8)NAME
lsmbstartup - Starts the Logical Storage Manager (LSM) during system reboot
SYNOPSIS
/sbin/lsmbstartup
DESCRIPTION
When LSM initially starts, it automatically adds the following lines in the /etc/inittab file, which ensure that the lsmbstartup script is
called during a system reboot:
lsm:23:wait:/sbin/lsmbstartup -n </dev/console>/dev/console 2>&1 fs:23:wait:/sbin/bcheckrc </dev/console>/dev/console 2>&1
The entry for /sbin/lsmbstartup must precede the entry for /sbin/bcheckrc.
LSM can be started only after the root file system is writable, so the lsmbstartup script first runs fsck -p on the root file system (if
non-AdvFS) and mounts the root file system writable. LSM startup scripts are then called to enable all LSM volumes. Any mirrored volumes
that have stale plexes are recovered in the background.

volsave(8) System Manager's Manual volsave(8)NAME
volsave - Saves a Logical Storage Manager (LSM) configuration
SYNOPSIS
/usr/sbin/volsave [-d dir]
OPTIONS
Directs the backup information to the directory specified by dir. This directory must not already exist.
DESCRIPTION
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 addi-
tion, 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 con-
figuration (allvol.DF, voldisk.list, and volboot). 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,
/usr/var/lsm/db/lsm.19970727131520.skylark).
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.
ERRORS
You may receive the following error message when using the -d dir option with the volsave command: Directory dir already exists
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 /usr/var/lsm/db.
FILES
Default directory containing timestamped subdirectories with LSM description sets. A volmake description file for all volumes, plexes, and
subdisks in a disk group. The volsave command creates a separate subdirectory and description file for each disk group on the system. A
description of the disks. This file is the output of the voldisk list command. The contents of the /etc/vol/volboot file. A header file
for the description set, containing a checksum, a magic number, the date of the file's creation, and the version of the volsave command.
