在AIX中如何使用vg备份/恢复的方法将数据转移到新存储设备供稿者：闫绪 恢复备份到新盘
恢复到hdisk4上去：
p615:/>restvg -f /dev/rmt0 hdisk4Will create the Volume Group: vg-local
Target Disks: hdisk4
Allocation Policy:
Shrink Filesystems: no
Preserve Physical Partitions for each Logical Volume: noEnter y to continue: y
vg-local
loglv00
lv-local
New volume on /dev/rmt0:
Cluster size is 51200 bytes（100 blocks）.
The volume number is 1.
The backup date is: Fri Jan 28 11:43:24 BEIST 2005
Files are backed up by name.
The user is root.
