I am going to make this one short and sweet. On a reboot, hosts that have access to RDM LUNs can take a LONG time to reboot. In order to correct to correct this we can set the hosts to have the LUNs perennially reserved. The only way to set this is by typing(sorry no …
A bit delayed but here it is. I sat the DCD a while at VMworld San Fran. Having never taken an exam at VMworld, this was an entirely new experience for me. Well, the PearsonVue exam experience, was pretty much like any other, I just didn’t realize how much it would affect my VMworld experience. With …
Let’s get started installing vCenter. It is never a bad idea to know what screens and information you will need before you get get there! Already this looks SIGNIFICANTLY more streamlined than the vSphere 5.5 installations with SSO, Inventory Service, etc etc etc Next next next! I went with Embedded Deployment, this means everything necessary …
This is especially useful for SMB who don’t have large environments, and can’t throw resources at a vCenter Server This is what one of my vCenter Servers looked like recently To give some insight, this is a vCenter that manages around 3 hosts and 50 VMs. I quickly found a KB about java memory usage …
Although VMworld 2014 US is now over, we can still continue to learn from it. Even if you accomplished everything you set out to do at VMworld, there is never a way to do everything there. Or Maybe you didn’t even have a chance to go to VMworld, and feel like you may have missed …

There were a couple of Hosts in a cluster that had been in maintenance mode for a while. One morning I look and see this error So naturally I see if there is a KB, and there is Sweet, that sounds easy enough to do… When Reconnecting.. That doesn’t seem to work …
Sometimes those hardware status Errors/Warnings do not want to clear even after you have fixed the issue In my case, I had a drive failed in a ESXi host that had 2 drives in Raid 1. No Biggie, just replace the drive. After replacing the drive and confirming everything was in the green(via an IBM …
