You can refer to the following steps:
1. If HA has been configured and the current node is the backup server, perform an HA switchover as follows:
a. Log in to the backup server by referring to Log In to the eBackup Server.
b. Run the su root command and enter the password of user root to switch to user root.
The default password of user root is Cloud12#$.
c. Run the following command to restart the eBackup service process. The active and standby nodes will be switched over.
service hcp restart
2. Replace the CPU.
