aix双机hacmp同步中总是失败，提示2边testvg的lv信息不一致，手工通过lsvg -l testvg 发现无不同，于是再如下命令：
1. A机上synclvodm -v testvg
2. B机上exportvg testvg，再importvg -y testvg hdiskpower2
3. 再次hacmp同步，还是报同样的错，于是猜测可能是2边ODM库lv信息不一致。
搜了下找到以下文章解决。

Sometimes situations occur where a logical volume is deleted, but the ODM is not up to date. E.g. when "lsvg -l" doesn't show you the logical volume, but the lslv command can still show information about the logical volume. Not good.
To resolve this issue, first try:
# synclvodm -v [volume group name]
If that doesn't work, try this: (in the example below logical volume hd7 is used). Save the ODM information of the logical volume:
# odmget -q name=hd7 CuDv | tee -a /tmp/CuDv.hd7.out
# odmget -q name=hd7 CuAt | tee -a /tmp/CuAt.hd7.out
If you mess things up, you can allways use the following command to restore the ODM information:
# odmadd /tmp/[filename]
Delete the ODM information of the logical volume:
# odmdelete -o CuDv -q name=hd7
# odmdelete -o CuAt -q name=hd7
Then, remove the device entry of the logical volume in the /dev directory (if present at all).
