设备odm库被锁定的处理

# rmdev -dl cd0
rmdev: 0514-516 Device configuration database lock service timed out.

后来连创建文件系统也挂起。
开始以为是卷组或者lvm-odm被锁定，尝试用chvg -u和putlvodm，均不得解。
查MessageGuide，原来是这样：
Device configuration database lock service timed out

Explanation:

You ran a command that tried to access a Configuration Object Data Management (CODM) file that is presently in use or was closed incorrectly.
User Response:

* Run the df command to determine if there is a process currently using any CODM file. If there is, wait until the process is completed and reissue your command.
* If you suspect that the CODM file was incorrectly closed, do the following:
1. Run the cd command to go to the /etc/objrepos directory.
2. Rename the config_lock file to config_lock.old using the mv command.
3. Reissue your command.

到/etc/objrepos目录下，移除config_lock文件后，原来不能执行的命令都顺利运行出结果。
