检测 css 进程:
aix1@grid[/home/grid]$crsctl check css
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Check failed, or completed with errors.
aix1@grid[/home/grid]$ps -ef|grep cssd

检测has进程:
aix1@grid[/home/grid]$crsctl check has
CRS-4639: Could not contact Oracle High Availability Services
说明ohasd进程没有启动,启动ohasd进程:
# ./ohasd start
Starting ohasd:
CRS-4123: Oracle High Availability Services has been started.
检查:
aix1@grid[/oracle11/app/grid/11.2.0]$ crsctl stat resource -t -init

接下就是要探讨为什么ohasd进程为什么在开机的时候没有自动启动?
原因是:安装grid 软件的lv不是自动挂载的。所以服务器在启动的时候是不能自动挂载grid所在lv,也就不能自动启动ohasd了。如果手动挂载lv,那么必须手动启动ohasd服务。
修改lv为自动挂载:
System Storage Management (Physical & Logical Storage)
-->File Systems
--->Add / Change / Show / Delete File Systems
-->Enhanced Journaled File Systems
-->Change / Show Characteristics of an Enhanced Journaled File System
选择要自动挂载点
Mount AUTOMATICALLY at system restart? yes ------由no改为yes即可
数据刚安装完成的时候,has进程是自动启动,用下面的命令设置自动启动;
aix1@grid[/home/grid]$crsctl enable has --启用自动启动
aix1@grid[/home/grid]$crsctl disable has --关闭自动启动
手动启动 has:
crsctl start has
crsctl stop has
查看has 的状态:
crsctl check has
ohasd 资源启动后,才能启动crs资源。
在11gR2中, ohasd包含了crsd、ocssd、evmd.
ohasd负责启动lower stack的集群资源, crsd负责启动上层的集群资源.
