19C GI修改名主机名后，无法正常启动GI ,CLSU-00107

[root@dbserver2 ~]# /u01/app/19.10.0/grid/bin/crsctl start has

CLSU-00107: operating system function: opendir; failed with error data: 2; at location: scrsearch1

CLSU-00104: additional error information: cant open scr home dir scls_scr_getval

CRS-4000: Command Start failed, or completed with errors.

解决办法：

1）移除旧主机名相关的配置信息

cd /u01/app/19.10.0/grid/crs/install

[root@dbserver2 install]# perl roothas.sh -deconfig -force

Using configuration parameter file: /u01/app/19.10.0/grid/crs/install/crsconfig_params

2）运行root脚本重新配置css服务

[root@dbserver2 install]# cd /u01/app/19.10.0/grid

[root@dbserver2 grid]# ./root.sh

Performing root user operation.

The following environment variables are set as:

ORACLE_OWNER= grid

ORACLE_HOME= /u01/app/19.10.0/grid

Copying dbhome to /usr/local/bin ...

Copying oraenv to /usr/local/bin ...

Copying coraenv to /usr/local/bin ...

Entries will be added to the /etc/oratab file as needed by

3）配置asm、database、listener等组件信息

[grid@sztest ~]$ srvctl add asm
