Since, we have never done a patching on all of the servers at the same, would like to have some insight and directions that we would need to keep in mind in this case.
have you seen https://www.suse.com/support/kb/doc.php?id=7012368 ? And please watch out for services running on those servers that may be required during updates - i.e. DNS servers, gateway functions or alike… you should update all servers at the same time then
A full distro update can put some load on the network and the SMT server, this need cause harm but is something to keep in mind, too.
As a starting point we have configured a SMT server to create a local repository for our servers.
I’d update the SMT server first. Once that one is at the current level, update the other machines.
I went the further configuration and for test registered one server with SMT, now the server is being listed in the clients list.
But, when I go to the new registered server and check online updates, it does not show any patches or updates available…
Is something missing here?
