Got a call tonight concerning a VM that was having some issues. We had p2v’d our Virtual Center and when the new vCenter came online, apparently DRS decided to balance the heck out of things and somewhere in the process, a VM got squished and had a variety of issues.
When I was brought in, it wasn’t powering up and throwing an error concerning a lock. So here is what I tried.
Last night I had a maintenance that went fine, but had a little hiccup that I wanted to write about. The maintenance was to simply add another block of WWN Initiators to our configuration and everything ran smooth.
Now, the reason for adding this new block is simply that we were out of WWNs and needed to turn up 4 new UCS B-200 blades. Well, since I have the new WWNs, might as well use them right?
How do you come up with a good time estimate? If you are a typical employee, there is a good chance that your job revolves not around day to day mundane tasks. There may be some of that, but there is a good chance that it revolves around completing projects. Yes, project oriented work is challenging and rewarding, but often done very poorly.
Not that your work is bad, its the management of the project that we suck at.
I’ve learned over the years that there is a timespan of hours that if my sleep falls into that range, I’m going to be a complete waste the next day. That range, 4-6 hours. If I get more or less sleep than 4-6 hours, I’m good to go. But for some reason that range is the death of me.
Last night due to a server maintenance that went south, I got 5 hours.
Living in the midwest teaches you a lot of different things. One of those lessons, Mother Nature always wins. She can be awesome with warm springs and falls that make the trees turn all sorts of wonderful colors. But she can also be pretty mean. A tornado can devastate mile wide tracks across the midwest. Floods can wipe out farms, homes and everything it reaches.
Winter in the midwest gives you the opportunity to experience freezing cold temps that would make a fish stick shiver.
