AIX 11G Rac Startup Error: CLSU-00100,CLSU-00101,CLSU-00103,CLSU-00104,CRS-4000

clsu-00100: operating system function: opendir failed with error data: 1
clsu-00101: operating system error message: nosuch file or directory
clsu-00103: error location: scrsearch1
clsu-00104: additional error information: can open SCR home dir SCLS_ scr_ getval
CRS-4000: Command Start failed, or completed with errors.

[ [email protected] scls_ SCR] $LS
Rac1
current host name
$host name
Rac2

Confirm that the host name has been modified. Other ways on the Internet say that has and grid need to be reconfigured.
after looking at the process, it’s rather cumbersome. Anyway, the host is cloned. Sima is a live doctor. He directly asks his colleagues in the host group to modify the host name and IP address. After confirming that there is no problem with the hosts content, restart the system and start the cluster and database again. OK
