Have you ever had one of those moments where you are working remotely on a system that could impact overall network connectivity, then midway through whatever it is that you are doing, your remote session drops out?
Yeah... I damn near just had a heart attack. I spent most of tonight patching XenApp servers in preparation for a large Edgesight rollout. During the early stages, while I was patching the data collectors, my remote session dropped and wouldn't reconnect. My first thought was 'dear god I broke the farm', but thankfully it was just my router being a piece of crap and rebooting for no reason.
Another odd discovery tonight was that our two load balanced web interfaces are configured differently. Not sure why that would have been done - it just doesn't make much sense - but it did cause me some confusion while testing data collector elections post patching. If the netscaler balanced my initial connection to the second WI and the first preferred data collector was offline, it wouldn't find the second one because it didn't have it listed, giving me no Xenapp applications. The first WI doesn't have this problem as it has both data collectors in its list.
I might look at bootstrapping the WIs to use a config file from one of the file clusters..
