I'm running xenserver 7.2 on a few M620 blade servers. I'm trying to apply XS72E004 and 005 patches. I go to the notification section and select Download/Install next to each patch. I have a pool created and if I leave the pool selected I can apply the update. I only want to patch each server one at a time though. When I try to select one server at a time though the patch is unavailable.
I tried putting the server in maintenance mode and that did not work. I tried downloading the iso and manually selecting it but not luck. Did Citrix change up the way patches are applied? I'd appreciate any suggestions or input.
