如果CTSSD服务无法正常启动，则在11.2中将无法正常启动HAS=>CRS导致RAC无法正常使用。 具体的诊断需要参考$GRID_HOME/log/$HOSTNAME/ctssd/octssd.log 的日志，例如：     
2010-12-23 16:45:31.287: [ GIPC][1257901344] gipcCheckInitialization: possible incompatible non-threaded init from [prom.c : 687], original from [clsss.c : 5325]
[ default][1257901344]Failure 4 in trying to open SV key SYSTEM.version.localhost

[ default][1257901344]procr_open_key error 4 errorbuf : PROCL-4: The local registry key to be operated on does not exist.
or PROCL-5
2010-12-23 16:45:31.289: [ CTSS][1257901344]clsctss_r_av2: Error [3] retrieving Active Version from OLR. Returns [19].
2010-12-23 16:45:31.292: [ CTSS][1257901344](:ctss_init16:): Error [19] retrieving active version. Returns [19].
2010-12-23 16:45:31.292: [ CTSS][1257901344]ctss_main: CTSS init failed [19]
2010-12-23 16:45:31.292: [ CTSS][1257901344]ctss_main: CTSS daemon aborting [19].
    触发该错误，主要有2种可能：
  1. ocr所在ASM DISK的用户权限存在问题
  2. ocr所在ASM DISK在节点之间设备名不一致
  3. HAS的状态不正常
