Last week we had a nice client of ours decide to rename the DNS name of a Media Agent they have on site without telling us first.
This obviously stopped all communication with the CommServe. We changed the name of the Media Agent in the CommCell thinking this would fix the issue, of course the CommCell said that it was unable to access the registry in that server and refused to update it correctly, keeping the MA offline. It wasn't until the guys at CV support messed around with the configuration for an hour or so and ended up putting in a firewall config on the MA that it started working correctly and came online. (Don't ask me why this worked there were no blocked ports between the two servers).
My question is what is the correct procedure to rename a media agent server. Please don't say uninstall the MA software then change the name of the server then reinstall, this will not work as we used SIDB and CDR which would, I am sure require re-seeding. There must be an easier way, or was what we did by renaming it in the CommCell the correct procedure but we were just unlucky that it did not work?
Thanks in advance for your help.
