VGEXPORT & VGIMPORT

Following example shows, how vgexport/vgimport can be used to change the Volume Group Names

# bdf /opt/test

Filesystem kbytes used avail %used Mounted on

/dev/vg01/lvol01 102400 1133 94945 1% /opt/test

# umount /opt/test

Step 1: Create a mapfile in the preview mode

# vgexport -p -v -s -m /tmp/vg01.map /dev/vg01

Beginning the export process on Volume Group "/dev/vg01".

Volume group "/dev/vg01" is still active.

/dev/dsk/c0t9d0

# vgchange -a n /dev/vg01

Volume group "/dev/vg01" has been successfully changed.

Step 2: Export the Volume Group

# vgexport /dev/vg01

# ll /dev/*/group

crw-r----- 1 root sys 64 0x000000 Oct 31 13:15 /dev/vg00/group

# mkdir /dev/vg01_renamed

# mknod /dev/vg01_renamed/group c 64 0x010000

Step 2: Import the Volume Group with a new name

# vgimport -v -s -m /tmp/vg01.map /dev/vg01_renamed

Beginning the import process on Volume Group "/dev/vg01_renamed".

Logical volume "/dev/vg01_renamed/lvol01" has been successfully created

with lv number 1.

Volume group "/dev/vg01_renamed" has been successfully created.

# vgchange -a y /dev/vg01_renamed

Activated volume group

Volume group "/dev/vg01_renamed" has been successfully changed.

# vgdisplay -v | grep "VG Name"

VG Name /dev/vg00

VG Name /dev/vg01_renamed
