The command ipa-replica-manage del does 2 things: removes all the agreements from/to the specified server and removes the server entry from LDAP. It's executed when you intend to completely remove a server and run uninstall on the removed server.

Did you intend to only delete the replication agreements? In this case the right command would be ipa topologysegment-del.

Why is service B unavailable after copy B is deleted and cannot be restored?Is this a normal phenomenon?How to recover?
Request big guy guidance, thank you!
