解决办法：
重新配置crs安装，具体如下
--查看下面的目录，发现有之前服务器名的配置文件目录
[oracle@hotel07~]$ cd /etc/oracle/scls_scr
[oracle@hotel07 scls_scr]$ ls
njdyw
--在root用户下
--进到$GRID_HOME/crs/install目录，执行下面的脚本
[root@hotel07install]# pwd
/u01/app/ora11g/product/11.2.0/grid/crs/install
[root@hotel07install]# ./rootcrs.pl -deconfig -force
Usingconfiguration parameter file: ./crsconfig_params
用法: srvctl <command> <object> [<options>]
命令:enable|disable|start|stop|status|add|remove|modify|getenv|setenv|unsetenv|config
对象: database|service|asm|diskgroup|listener|home|ons
有关各个命令和对象的详细帮助, 请使用:
srvctl <command> -h 或
srvctl <command> <object> -h

--然后再看crs配置目录
[oracle@hotel07~]$ cd /etc/oracle/scls_scr
[oracle@hotel07scls_scr]$ ls
hotel07
--查看crs状态

--如果缺少其它服务用srvctl命令进行添加

原文内容：
With 11.2 database, if thehostname is changed we’ll see following error while starting the HASservices
dev-srv-20:+ASM:/home/ora11gr2>crsctl start hasFailure at scls_scr_create with code 1Internal Error Information: Category: -1Operation: has_ha_privs Location: scrcreate5 Other: need ha priv System Dependent Information: 0 CRS-4000: Command Start failed, or completed with errors.To make sure, it is due to changein hostname check the directory in the following path. As we can see thehostname with which HAS was originally configured is different fromcurrent hostname.
dev-srv-20:+ASM:/etc/oracle/scls_scr>ls -altotal 0drwxr-xr-x 3 root epsdba 80 2009-05-12 08:36 .drwxr-xr-x 5 root epsdba 200 2010-03-08 14:27 ..drwxr-xr-x 4 root epsdba 96 2009-05-12 08:36 dev-srv-25
So to fix the problem
1. De-configure the CRS
$GRID_HOME/crs/install/rootcrs.pl -deconfig -force2. Reconfigure CRS
