NAME
vgrestore — restore a VxVM disk group back to an LVM volume group
SYNOPSIS
/usr/sbin/vgrestore vg_name
DESCRIPTION
The
vgrestore
command restores a Logical Volume Manager (LVM) volume group that
was previously converted to a VxVM disk group by the
vxvmconvert
utility.
ARGUMENTS
- vg_name
Specifies the name of a volume group that was converted to
a VxVM disk group by the
vxvmconvert
utility.
EXIT CODES
vgrestore
exits with one of the following values:
- 0
Successful completion.
- >0
Failure;
an error occurred.
WARNINGS
vgrestore
functions only on VxVM disk groups that were converted from
LVM volume groups by the
vxvmconvert
command.
It is a good idea to back up user data before running
vgrestore,
and restore it after the
vgrestore
completes, as
vgrestore
can only restore a logical volume back to the state it was
in before conversion to VxVM.
If data changed on the volume while it was a VxVM volume,
the changes won't be reflected on the volume after
being restored to LVM.
As part of the original conversion process,
applications that once referenced the now-converted LVM
volume's path names may have changed to reference VxVM
volume special device file names.
Alternatively, special device file path names originally representing
the now-converted LVM volumes may have changed to symbolic links
pointing to the VxVM volume path names.
Be sure to undo these actions when restoring back to LVM.
Do not use
vgrestore
unless you are certain that you want to restore LVM volume groups.
After
vgrestore
this is run,
the VxVM disks will no longer exist.
EXAMPLES
To restore the LVM volume group
vg03
that was converted by
vxvmconvert
to the VxVM disk group
