증상

If you have not recently upgraded, then disable/enable http/https services.

If you have upgraded recently, then you will need to Regenerate the self-signed CA and host certificates. Regenerating the certificates breaks existing trust relationships with external systems.

User is unable to launch Data Domain System Manager from any Web Browser, error displayed is "The GUI Service is temporarily unavailable. Please refresh your browser. If the problem persists, please contact DataDomain support for assistance".
However user can login to Data Domain system using SSH and can run all commands, the screenshot  below is for reference.

원인

• This issue can occur at times when DD system is under heavy load (high backup/replication/cleaning activity) or if there happened to be temporary communication issue with web service.

 

• This issue can also occur when DDOS is upgraded to 6.x family from 5.6.x or 5.7.x platforms. For environments that use self-signed SHA-256 certificates, the certificates must be regenerated manually after the DDOS upgrade process is complete, a trust must be reestablished with external systems that connect to the Data Domain system.
