Unmount the logical volume on the HDLM device.
In the following example, the logical volume subject to the move has been
mounted on
/mnt/lvol1
:
# umount /mnt/lvol1
2. Deactivate the volume group.
In the following example, the logical volume subject to the move belongs to the
vg01 volume group:
# vgchange -an vg01
0 logical volume(s) in volume group "vg01" now active

If Xen is being used, make sure that domainU has been stopped. If domainU has been
set up to automatically start whenever domain0 starts, temporarily change the setting
so that domainU will not start automatically.
