VCSA 7.0 Update 2 Upgrade Issue - Exception occurred in install precheck phase

by // 23 Comments

Like most folks, I was excited about the release of vSphere 7.0 Update 2 and I was ready to upgrade my personal homelab, which was running on vSphere 7.0 Update 1c. However, after starting my VCSA upgrade in the VAMI UI, it quickly failed with the following error message: Exception occurred in install precheck phase

Given the release had just GA'ed less than an hour ago and everyone was probably hammering the site, I figured I would wait and then try again.

Using PowerCLI to automate the retrieval of VCSA Identity Sources

by // 3 Comments

Similiar to automating the retrieval of the vCenter Server Appliance (VCSA) password policies using PowerCLI, we can extend that example and leverage the Guest Operations API via Invoke-VMScript cmdlet to also retrieve the identity sources configured for a given VCSA without requiring SSH access.

I have created a new VCSA.psm1 PowerCLI Module which now includes the previous Get-VCSAPasswordPolicy function along with the new Get-VCSAIdentitySource function which accepts the name of the VCSA VM and root password to the VM as shown in the screenshot below.

If you need to add a specific Identity Source such as an Active Directory Domain which you have joined the VCSA, you can simply use Invoke-VMScript cmdlet and pass in the following command:

/opt/vmware/bin/sso-config.sh -add_identity_source -type nativead -domain vmware.corp

How to deploy the vCenter Server Appliance (VCSA) with a custom MAC Address?

by // 1 Comment

I recently had a question that came in from our field where a customer needed to deploy the vCenter Server Appliance (VCSA) with a specific MAC Address which was a requirement to ensure property connectivity within their network. This type of network requirement is not really new or unique, it is a common practice used to ensure only valid VMs with a static DHCP reservation can actually connect to a specific network but it certainly was the first time I had heard of this request for the VCSA.

With the default VCSA installer workflow, there is currently not a way to modify the network MAC Address which is automatically generated after the deployment of the OVA. Having said that, I have spent quite a bit of time exploring the various non-standard methods of deploying the VCSA in the past (see here, here and here) and with that information, you definitely can affect the MAC Address while still maintaining a valid VCSA deployment. With a bit of trial/error, there are two options depending if you are deploying the VCSA directly to an ESXi host (for initial setup) or to an existing vCenter Server. To demonstrate how this works, I have created a basic shell script called VCSAStaticMACAddress.sh which you can easily adapt to for a Windows-based environment.

The trick is that when you deploy to a vCenter Server endpoint, the required OVF properties are persisted which would allow you to only deploy the VCSA but not actually power it on and there you can easily augment a number of settings including the MAC Address. In the case of deploying directly to an ESXi host, OVF properties are not persisted and hence a challenge if you wish to make changes prior to powering on the VM. In earlier versions, it was possible to set these OVF properties by way of using the extraConfig property of the VM but it looks like this trick no longer works and requires a slight variation of the workflow which is described in the instructions below.
