vgrestore

vgrestore(1M)															     vgrestore(1M)

NAME

       vgrestore - restore a VxVM disk group back to an LVM volume group

SYNOPSIS

       /etc/vx/bin/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 vxvm-
       convert 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 dg03, enter:

	      vgcfgrestore vg03
