2、执行cfgmgr 出错
# cfgmgr -v
......
Calling savebase
Return code = 1
*** no stdout ****
*** no stderr ****
cfgmgr: 0514-609 Unable to save the base customized information
on /dev/ipldevice.
修复启动lv：
# bosboot -ad /dev/ipldevice
0301-168 bosboot: The current boot logical volume, /dev/hd5,
does not exist on /dev/hdisk5.
同步lv：
# synclvodm -P -v rootvg
