启动DM报错： 

HMGR0021E: An error was encountered while processing the core group document.
The exception is java.io.FileNotFoundException: /IBM/WebSphere/AppServer/profiles/dmgr01/config/cells/jsapp1Cell01/nodes/jsapp1Node01/servers/dmgr/hamanagerservice.xml (No such file or directory)

其中jsapp1Node01为不再使用，也不受DM控制的NodeName。

解决办法：删除/IBM/WebSphere/AppServer/profiles/dmgr01/config/cells/jsapp1Cell01/nodes/下的jsapp1Node01目录后启动成功。

在DM启动着的时候，启动jsapp1Node01的NodeAgent就会在目录/IBM/WebSphere/AppServer/profiles/dmgr01/config/cells/jsapp1Cell01/nodes/、

/IBM/WebSphere/AppServer/profiles/appsrv01/config/cells/jsapp1Cell01/nodes/、

和/IBM/WebSphere/AppServer/profiles/appsrv02/config/cells/jsapp1Cell01/nodes/下面生成jsapp1Node01的配置文件，删除目录jsapp1Node01 后DM、NodeAgent都可以启动成功。
