Full Discussion: Rhel upgrade - pre maintenance checklist
Operating Systems Linux Red Hat Rhel upgrade - pre maintenance checklist Post 302891259 by Perderabo on Tuesday 4th of March 2014 03:40:51 PM
Old 03-04-2014
I have done RHEL updates and encountered problems. This is because we install RedHat on hardware not officially supported by RedHat. For example while RedHat supports some Dell Precision workstations, they do not support any Dell Optiplex workstations and we use them. The upgrades typically break because the new kernels need newer drivers. So I get complete info on my hardware configuration before I do an upgrade. The two big items are Video card and Network interface.
