NAME
dgcfgbackup — create or update VxVM volume group configuration backup file
SYNOPSIS
/usr/sbin/dgcfgbackup
[-f
dg_conf_path]
dg_name
DESCRIPTION
The
dgcfgbackup
command saves the VxVM configuration for a disk group
in a default or alternate configuration backup file (see the
-f
option).
By default,
dgcfgbackup
runs automatically each time a VxVM command changes the VxVM configuration.
In this case, it always uses the default configuration backup file.
An existing default configuration backup file is renamed with an extension of
.old.
Options and Arguments
dgcfgbackup
recognizes the following options and arguments:
- dg_name
The name of a disk group.
- -f dg_conf_path
Save the configuration using an alternate file name specified by
dg_conf_path.
If
-f
is omitted, the default file name is in the form:
/etc/vxvmconf/dg_name.conf
RETURN VALUE
dgcfgbackup
exits with one of the following values:
- 0
Successful completion.
- >0
Failure.
Errors occurred when information from the disk group was being accessed.
EXAMPLES
Back up VxVM configuration information for disk group
testdg
in the default backup file
/etc/vxvmconf/testdg.conf:
Back up VxVM configuration information for disk group
datadg
in the alternate configuration backup file
/tmp/datadg.backup:
dgcfgbackup -f /tmp/datadg.backup datadg
WARNINGS
It is recommended that any alternate configuration backup file
be created in the root file system
(as is the case with the default path name).
This facilitates easy disk group recovery during maintenance mode,
such as after a system crash.
