For the past week, I have been troubleshooting the strangest issue. I have been attempting to move some Windows 8.1 VM’s from our legacy datacenter(iSCSI) to our new datacenter(FC). Whenever I would move the VM to our new DC, it would fail to boot properly. It would boot straight to Windows Recovery. If I moved the same VM to any other type of storage(NFS, iSCSI, Local) the VM would boot perfectly fine.
Welcome to my post about upgrading your VMware vCenter Server Appliance (VCSA) to 6.0 U1b. This process is very straight forward. We will begin with updating our Platform Service Controllers (PSC) and then proceed with the vCenter Appliance. SSH to your Primary PSC. If you are currently in the bash shell, type appliancesh to switch shells to run the update. Run software-packages install –url –acceptEulas to download and install the packages from the VMware Repo.

It’s patch time! That means time to upload the firmware bundles to all my UCS domains. Instead of doing it manually I figured i would create a quick script to do that for me. Pre-Requsites UCS Powertool Link to Script UploadUCSFirmware.ps1 Preparing to Execute the Script The script is pretty straight forward, just need to define a few variables seen below and then you execute the script.
It is now VCAP6-Design study time! Here is my blueprint laid out, and hopefully will be populated with some content. Section 1 – Create a vSphere Conceptual Design Objective 1.1 – Gather and analyze business requirements Skills and Abilities Associate a stakeholder with the information that needs to be collected. Utilize inventory and assessment data from a current environment to define a baseline state. Analyze customer interview data to explicitly define customer #### Objectives for a conceptual design.

Im finally getting to dive back in to working with UCS. My latest task with my project of configuring 9 UCS Domains, was configuring the Policy Backup and Export. See below on how to automate this process! Pre-Requsites UCS Powertool Link to Script Set-UCSPolicyBackupandExport.ps1 Preparing to Execute the Script The script is pretty straight forward, just need to define a few variables seen below and then you execute the script.
Im finally getting to dive back in to working with UCS. My latest task with my project of configuring 9 UCS Domains, was swapping out certificates. The first few I did via the GUI, and I thought can this be scripted? Well the answer is yes! See below for information on executing the script. Pre-Requsites UCS Powertool Link to Script AddUCSCert.ps1 Preparing to Execute the Script The script is pretty straight forward, just need to define a few variables seen below and then you execute the script.
Normally when i need to install and update a host VIB I use Update Manager. However there is currently a bug with Cisco’s latest enic/fnic drivers that wont let you install them via UM. I had to run these updates on over 50 hosts and I really didn’t want to have to ssh and install it manually. Lucky I remember Brian Graf’s Host Client Install Fling and borrowed some of the code to come up with the below script.
Ever needed to modify a DVS uplink configuration from ESXi Shell? I am currently troubleshooting some issues with DVS uplinks no longer being assigned on reboot. As a heads up. If you are doing this on ESXi 6.0.. don’t. It can cause an issue with the proxy DVS having different ID than the actual DVS causing my original issue, still working with VMware Support to find out more details. After “Restoring Network Configuration” a few too many times, I finally realized I could just add the uplinks back via CLI until support can figure out why this is occurring, here are the details on how to manage the uplinks on a DVS via CLI.
We are currently working on some Cisco ACI Integration and wanted to add a large VLAN Pool to a UCS Configuration. Since currently Cisco UCS does not allow selecting multiple VLAN’s easily when adding to a VLAN Group or vNIC Template, we now have a pretty decent script that will do it for you. The script can be found here.</p> <h1 id="powercli-script-for-adding-vlan-to-vlan-group-and-vnic-template-davidstamen-http-davidstamen">PowerCLI Script for adding VLAN to VLAN Group and vNIC Template # @davidstamen # <a href="http://davidstamen">http://davidstamen</a>.</h1>
Ever wonder why a VM isn’t on the network? I was working on deploying some test VM’s and for some reason all the VM’s that were cloned decided to start with the network disconnected, and the connect on power on was also not selected. I decided to throw together this quick one-liner that will make sure every VM is set to start connected on power on and is currently connected.
