We have migrated our SAS server from centos 6 to 7 and in the process changed the hostname. The previous name still resolves via dns. The backups have failed since then. The errors indicate what is wrong but I am not familiar at all with SAS and the manuals referenced are not helpful. It would be nice to know how to fix this at the command line. Here are the errors:
The backup failed Error Code: 655, Stack Trace: Primary metadata server is not reachable using SAS Deployment Agent. Please make sure that the agent is running on it.
Primary tier is not set. Please make sure that primary metadata tier is not excluded.
