So I had an interesting little problem this morning. I got a call from a fellow engineer asking if something was wrong with our vCenter 5.1 server. He couldn’t log in. Obviously, that’s more than a little concerning so I told him I’d take a look at it. I brought up my client and attempted to sign in and received the following error:
A general system error occurred: Authorize Exception
This wouldn’t be Frank’s Tech Support and Pretty Good Sandwiches without the occasional sangwidge, and since my boss was nagging me to fill this gaping hole in my blog, today I present to you a new twist on an old favorite. I call it the Inside-Out Grilled Cheese.
When I was growing up, my mom always made the regular kind of grilled cheese. You know, two slices of white bread and a couple of slices of Processed American Cheese-Like Substitute And Floor Tiling. I’ll be honest with you, served with a mug of tomato soup, it’s still comfort food and I’ll still make it from time to time. But we’re adults now and sometimes we want more out of our sangwidges. We want them to be Pretty Good, right? They don’t have to be great. I mean, let’s not get ahead of ourselves here. Do I look like Guy Fieri? No. I do not. You’ll just have to take my word on that. So let’s grill a pretty good cheese.
I hate PowerCLI. There. I said it. I’m not a programmer. I can barely script. My upcoming VCAP exam pretty much requires some proficiency in PowerCLI. Perhaps you see my dilemma. Since I have to know it, I figured I’d better learn it. I decided to get started with something relatively simpe: Backing up my host configs. I’m going to show you how and I’m going to explain the commands.
In one of our data silos, we’ve been using a lot of spreadsheets and manual tracking to manage physical-to-virtual cross-connects between our physical switches and our ESXi hosts. There are a couple of reasons for this. The first is that up until recently, the silo was using non-Cisco switches and the second is that the licensing on our hosts don’t allow for LLDP, only CDP. We only have Standard licensing and Enterprise is required for distributed switches. Only distributed switches can do LLDP, so we were stuck with a protocol that we couldn’t use with our physical switches. Now that we’re in the process of migrating the silo to some newer hardware, I’m preparing to do a small redesign of our environment.
