This morning I was late to work because as I backed out of the driveway I noticed that my wife's car had a flat tire. This should be a pretty simple thing to fix, but it turns out that the spare tire was also flat. This too should have been an easy fix because I have a 60 gallon air compressor standing in the corner of my garage that is always charged with air, but as luck would have it since I don't use it to fill tires with air that often (it was used primarily for media blasting my Mustang last year), I couldn't find the correct air chuck I needed to air the tire up. This resulted in a trip to the local gas station to air the spare tire up and then back to the house to put it on the car.
This story serves as a good reminder to test your DR/HA plans before you actually need to use them. Most people keep a spare tire in their trunk to cover the occasion that you have a flat on the road, to get you to the nearest tire shop (at least I do). However, if I had actually been on the road, my spare was quite useless since it was completely flat. I keep another option in my pocket with AAA, so if I had been on the road, I could have called them to come out. However, what if it was a true emergency situation where I had to get to the hospital for something? Do I really want to wait a half an hour or more for support to show up to fix what should have been a simple problem with proper tests/checks ahead of time.
My wife knows how to change a tire, she's done it before, but she's not as good at doing it as I am. She's kind of like our Jr. DBA, she can do the work, but if I am around it is sometimes faster/easier for me to just take care of things. If I hadn't been home, she wouldn't have been able to fix the problem anyway, she would have had to call AAA for assistance. This leads to my second note, you should plan for and know your support options before you are in a problem situation. One of the documented steps in our run book for when I am unavailable is to call Microsoft Support if a problem seems to complex, or is beyond the available knowledge for troubleshooting. Certainly this is going to take longer to reach a solution to the problem, but it can be faster than if you try to hack your way to a solution manually (walking to the gas station to put air in the tire would have taken longer than waiting on AAA I am sure).
So my question to you is, have you checked your DR/HA strategy lately, and when's the last time you checked your spare tire pressure? If you have, do you know where all of the tools are in case you actually need them? Thankfully this morning the problem occurred in a controlled environment that allowed me to solve it without to much delay. I checked the spare in our van, and it too was flat, so I aired it up as well, future crisis averted hopefully.
