So my Windows based Vmware Vcenter Server went belly up again. Something to do with the SSO database not starting. Not being a lover of Windows I decided to give the Vcenter Server Appliance a shot. Install was great and I am kicking myself a bit as to why I spent so much time fighting with Windows. My new Vcenter Server, which has a different IP address then the original Windows box (might make a great Veeam server) was not registered with Vcenter Operations Manager. I was not prepared to reinstall that thing again. So I needed to figure out how to manually unregister a Vcenter instance and add register another one in its place.

ESX 5: How to Power On A Virtual Machine from the Command Line
So lately I have been noticing some strange issues with my home lab. Every so often I find my all my virtuall machines are down, however the ESX box is up and running fine. Checking the logs on the ESX server has not helped me get to the bottom of the issue, rather I can just see the messages that the server has rebooted. So at the very least I know that something is happening to the ESX server causing it to crash.
Install and Configure SNMP on the Asus RT-AC66U Router
Ok first off let me start by saying that this is probably the coolest piece of home computing hardware that I have ever laid my hands on. Yes the setup was easy, and yes the thing is rock solid, and yes wireless range is awesome. But for approx $200 USD you really should not expect anything less. I'm not going to go into its specs or features, as I'll leave that to the professions. Read up on it here.
XenServer: How to Build and Configure a Dedicated NFS Storage Bond
GodzukiFirst of all let me start this off by saying that there is a lot of information out there on how to setup a dedicated storage interface on XenServer. However, I was unable to find anything specifically related to bonding two unmanaged interfaces and use them for as a dedicated uplink, which is seems rather silly to me as why would you not want to have a highly redundant network connection to your NFS storage. I digress.
Cisco UCS Failover Via 6248 CLI
Need to fail over Cisco UCS Manager from one 6248 to another. Oh did I mention that you are in a hurry because you are going to have to sift through pages and pages of pdfs to get the information. I found this out the hard way. Anyway, out of the kindness of my heart I have documented this process below.
Patching ESXi 4.1 via the Linux RCLI
Great Balls of Frustration... could the documentation be anymore confusing and convoluted regarding the process of patching an ESX server via the Linux remote cli.
No, I am not running windows, and no I am not on the local ESX console, and no I am not running the Vmware Management Appliance, and most of all, no I do not want outdated instructions from 2008. I just want to download some patches to my local linux destop and patch my ESX servers. Specifically I want to install the latest and greatest Qlogic drivers to troubleshoot a SAN connectivity issue that I will probably blog about at a later date.
Anyway here is how I did what I needed to do without resorting to using a windows box.
Forcibly Remove Storage Devices From XenCenter via CLI
This is my second post in focused on forcibily something from XenCenter, as apparently XenCenter has a hard time knowing when to "forget" a device or host on its own. Now while this is annoying, it can be resolved rather easily from the command line. Now, lets take a step back and reflect for a … Continue reading Forcibly Remove Storage Devices From XenCenter via CLI
