Troubleshooting Start HAS fail “Operating System function: opendir failed with error data: 2 error location: scrsearch1”

一套Oracle 11G standalone环境数据库文件在ASM中,几年没有重启的老系统,操作系统重启后,启动HAS服务失败, 提示如下错误:
as root

# /u01/app/11.2.0.3/grid/bin/crsctl start has
CLSU-00100: Operating System function: opendir failed with error data: 2
CLSU-00101: Operating System error message: No such file or directory
CLSU-00103: error location: scrsearch1
CLSU-00104: additional error information: cant open scr home dir scls_scr_getval
CRS-4000: Command Start failed, or completed with errors. 

检查 init.ohasd

# grep ohasd /etc/inittab
h1:35:respawn:/etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null

# ps -ef| grep init.ohasd | grep -v grep
-- 进程存在, 如果未启动  nohup ./init.ohasd run &

检查主机名

# hostname 
# cat /etc/hostname
# hostnamectl --static

# ls -l /etc/oracle/scls_scr/

# cat /etc/hosts

发现主机名有修改过,只是在hosts增加了映射,恢复主机名

# vi /etc/sysconfig/network
# hostnamectl set-hostname

启动HAS 服务正常, 如果alert提示alert日志提示TIMED OUT WAITING FOR OHASD MONITOR 重启OS.
