EXTERNAL INFLUENCES

Environment Variables

LANG determines the language in which messages are displayed.

LANG is not speciﬁed or is null, it defaults to "C" (see lang (5)).

If any internationalization variable contains an invalid setting, all internationalization variables default

to "C" (see environ (5)).

EXAMPLES

Back up LVM conﬁguration information for volume group

/dev/vg00 in the default backup ﬁle

vg00.conf in the conﬁgured path:

vgcfgbackup /dev/vg00

Update LVM conﬁguration information corresponding to volume group

/dev/vg00

in the default

backup ﬁle

vg00.conf in the conﬁgured path:

vgcfgbackup -u /dev/vg00

Back up LVM conﬁguration information for volume group /dev/vg00 in the alternate conﬁguration

backup ﬁle /tmp/vg00.backup

vgcfgbackup -f /tmp/vg00.backup vg00

WARNINGS

It is recommended that any alternate conﬁguration backup ﬁle for any bootable volume group be created

in the root ﬁle system (as is the case with the default path name). This facilitates easy volume group

recovery during maintenance mode, such as after a system crash.

It is recommended that the

LVMP_CONF_PATH_NON_BOOT

directory be held on a logical volume within

the root volume group. If the

LVMP_CONF_PATH_NON_BOOT

directory is held on a logical volume in a

different volume group, and this volume group cannot be activated, then recovery via

vgcfgrestore

will not be possible.
