问题描述：

在Grid环境中，如果修改了主机名，启动Grid时会出现如下错误：

[grid@sztest ~]$ sqlplus / as sysasmSQL*Plus: Release 12.1.0.2.0 Production on Wed Apr 15 20:42:27 2020Copyright (c) 1982, 2014, Oracle.

检查css服务：

[grid@sztest ~]$ crsctl check cssCRS-4639: Could not contact Oracle High Availability ServicesCRS-4000: Command Check failed, or completed with errors.

启动has服务：

解决方案：

1）移除旧主机名相关的配置信息

[root@sztest ~]# cd /u01/app/grid/product/12.1.0/grid/crs/install/[root@sztest install]# perl roothas.sh -deconfig -forceUsing configuration parameter file: /u01/app/grid/product/12.1.0/grid/crs/install/crsconfig_paramsCRS-4639: Could not contact Oracle High Availability ServicesCRS-4000: Command Stop failed, or completed with errors.CRS-4639: Could not contact Oracle High Availability ServicesCRS-4000: Command Delete failed, or completed with errors.CLSU-00100: operating system function: opendir failed with error data: 2CLSU-00101: operating system error message: No such file or directoryCLSU-00103: error location: scrsearch1CLSU-00104: additional error information: cant open scr home dir scls_scr_getvalCRS-4639: Could not contact Oracle High Availability ServicesCRS-4000: Command Stop failed, or completed with errors.2020/04/15 20:46:44 CLSRSC-337: Successfully deconfigured Oracle Restart stack

2）运行root脚本重新配置css服务

[root@sztest install]# cd /u01/app/grid/product/12.1.0/grid/[root@sztest grid]# ./root.shPerforming root user operation.The following environment variables are set as:ORACLE_OWNER= gridORACLE_HOME= /u01/app/grid/product/12.1.0/gridEnter the full pathname of the local bin directory: [/usr/local/bin]:The contents of "dbhome" have not changed.

3）配置asm、database、listener等组件信息

[grid@sztest ~]$ srvctl add asm[grid@sztest ~]$ srvctl start asm[oracle@sztest ~]$ srvctl add database -db orcl -oraclehome /u01/app/oracle/product/12.1.0/dbhome_1 -diskgroup "DATA,FRA"

从12.1.0.2开始，roothas.sh脚本替代了roothas.pl脚本。
