We recently had need to evacuate one of our busy SAN arrays. For the most part, this was easy enough. Thanks to the storage vMotion (SvMotion) capability, it was easy enough to move the virtual machines without much difficulty using the normal migrate processes while the vm’s were up and running. The trouble comes...
Another interesting one for folks. This is the first time I’ve seen this, as most of my storage comes off of my SAN. We started getting alerts for virtual machines, and after pulling up the vm console, noticed it was black. Tried to reset the vm, but the reset task just sat ‘In Progress’...
Finally getting back into the swing of things with the new year. So, for my first post of 2012, a plug for the local VMware Users Group Meeting (DCVMUG). The event is @ Nationals Park on January 17th, 2012. Should be a good event, with presentations from Veeam and Tintri, and of course a...
I’ve been hunting this problem down for almost a week now, and was finally able to resolve the issue. Having spoken to others, not sure why we were affected by this, but I suppose that is life, and if nothing else, I got to dig into the weeds with the View Event DB configuration....
Started troubleshooting a few issues with our View 4.6 environment and generally cleaning things up, and ran into an issue that I found rather annoying to fix. We started receiving provisioning issues from the connection brokers. Provisioning desktops would fail, desktops would fail to power on. And the ones that were on were not...
I was reading through some posts on the VMTN forums today, and a poster ran into an issue where his network performance dropped significantly after upgrading to ESXi 5. Poster checked through the usual suspects: config changes, speed and duplex on host and switches. Even went through and turned off TCP Offloading on the...
After having gone through a few different trainings (Cisco/RHEV/Hyper-V/Oracle OVM), I finally got back to some good ‘ole VMware learning. Went through some docs, and decided to go after VCP5. Glad to say that I did pass, and that the new Version 5 exam is much better a “test” than version 4 was, at...
“The system has found a problem with your machine and can not continue. LINT1 motherboard interrupt. This is a hardware problem; please contact your hardware vendor.” Now this system was just running software, so I didn’t believe that there was a hardware issue, per se. So, next step, I went through the tedious process...
Red Hat has finally released a supported method to fence RHEL cluster nodes running on top of ESX hosts. You need to be running 5.7, but it is finally officially supported, see support matrix here. Now this has been a sticking point to running Red Hat cluster inside of a VMware ESX cluster now...
I recently had the great honor of upgrading several ESX 3.5 hosts to the latest 4.1 release. This typically would not be such a chore, thanks to Update Manager, but these hosts were installed quite some time ago, and never updated after the fact. So, I attempted to perform the typical update procedure, and...
I wrote this script a little while ago to see how much disk space I was actually using inside of my virtual machines. While I was at it, I included the allocated CPU and Memory. With the new proposed licensing model for vSphere 5, it seemed to gain some more life. Seems pretty appropriate...
Having more than a handful of servers to deal with, it is more than a little helpful to have logs in one place. That way, you can log in to one location, and parse through logs to your heart’s content. One thing that gets a bit difficult to do, however, is event correlation. Sure,...
Now, after the 4th/5th time running into this predicament, I thought I’d share with others. The first time, maybe two, we thought we may have run into some small anomaly. After the 3rd time, there had to be some bug. Now, after moving to new equipment, we’re at a bit of a loss. Last...
After 1 year, I decided I wanted a few more features than the basic wordpress.com was allowing me, so I’ve moved. Takes a lot more than I initially thought, but I’m about as setup as I’m going to be. At least for now. Hopefully, all goes well, and I don’t mess up links. My...
Just ran into an annoying issue which everyone should be aware of. We have a vm with a 2 TB RDM exported through a NetApp array. This vm has been all fine and dandy, and perfectly happy living on the ESX 3.5 host it is currently on. Come time to upgrade, and the new...
May 10, 2011. It is now officially one year since this blog first started. Along the way, I’ve posted a few issues, a few opinions, some news, and hopefully helped a few folks along the way. I’d like to say this is only the beginning, and I guess I can only go up from...
Just ran into an interesting, read annoying, limitation with using Emulex HBA’s in my environment. I haven’t been able to find official confirmation of this in a whitepaper or document out there, so take it as my experience, and not necessarily the same in every case. I was trying to upgrade some 3.5 boot...
The title says it all. I had one remaining vSphere 4.0 environment left to upgrade. I’ve done several already, and thought this one would be a breeze. I’ve been dragging my feet on this last one since it hosts a Lab Manager install as well. Well, the time finally came. I started with the...
