crsctl start cluster 和crs start crs 有什么区别

q：Crsctl start cluster 是 11.2 新特性和 crsctl start crs 有啥区别呢？
Crsctl start/stop crs 管理本地节点的 clusterware stack 的启停，包含启动 ohasd 进程，这个命令只能用来管理本地节点
。
[root@vmrac2 ~]# crsctl start crs -h
Usage:
crsctl start crs[-excl [-nocrs]|-nowait]
Start OHAS onthis server
where
-excl Start Oracle Clusterware in exclusivemode
-nocrs Start Oracle Clusterware in exclusivemode without starting CRS
-nowait Do not wait for OHAS to start

crsctl start/stop cluster - Manage start/stop the Oracle Clusterware stack onlocal node if you do not specify either -all or -n and nodes remote if option-n or -all be specified , NOT includingthe OHASD process. You can't start/stop clusterware stack without OHASD processrunning.

crsctl strat/stop cluster 既可以管理本地 clusterware stack ，也可以管理整个集群
指定 –all 启动集群中所有节点的集群件，即启动整个集群。
-n 启动指定节点的 集群件
但是不包含 OHASD 进程。 You can't start/stop clusterware stack without OHASDprocess running.

[root@vmrac2 ~]# crsctl start cluster -h
Usage:
crsctl startcluster [[-all]|[-n [...]]]
Start CRS stack
where
Default Start local server
-all Start all servers
-n Start named servers
server [...] One or more blank-separated server names

Despite crsctl start/stop crs manage entire Oracle Clusterware stack on localnode crsctl start/stop crs not allow you to manage remote nodes, unlike crsctlstart/stop cluster that allows you to manage all the nodes, but if the processOASH is runing.
crsctl start/stop crs
只能管理本地节点的 clusterware stack ，并不允许我们管理远程节点。

但是当远程或者本地节点 OHASD process 运行时（ Oracle High AvailabilityServices服务必须可用），才能使用 crsctl start/stop crs 管理所有节点
