RAC如何启动状态为UNKNOWN的资源&&PRKS-1009,CRS-1028,CRS-0223

现象：
RAC的一个节点起不来，crs_stat查看发现很多资源状态都为offline
[Oracle@rac1 ~]$ crs_stat -t

stop之后再start还是不行。

分析：
资源状态因为某种原因变为UNKNOWN，，导致无法通过正常方式启动。

解决方法：
客户的系统比较重要，当时先恢复业务，再仔细分析原因。
恢复业务的方法如下：
先强制停止状态为UNKNOWN的资源：
crs_stop -f ora.rac2.ASM2.asm
crs_stop -f ora.rac2.lsnr
再重新启动资源：
crs_start -all
重启之后业务恢复正常。
