volsave(8)volsave(8)NAMEvolsave - 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
The volsave command creates an LSM description set that consists of a
header file and other files containing information about the LSM con‐
figuration. Refer to the FILES section for details on the contents of
By default, the description set is saved to a timestamped directory in
/usr/var/lsm/db (for example, /usr/var/lsm/db/LSM.19970727131520.sky‐
The -d option can be used with volsave to specify a particular direc‐
tory 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 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 direc‐
tory 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 subdirecto‐
ries 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 vol‐
make command for all volumes, plexes, and subdisks in a disk group.
There is one file for each disk group, stored in the diskgroup.d subdi‐
rectory. A description of the disks. This file is the output of the
voldisk list command. A description of the disk group based on infor‐
mation 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 num‐
ber, the date of the file's creation, and the version of the volsave
command, that volrestore validates before executing.
