While I was busy at at customer upgrading their VMware environment, I ran into a strange issue.
The upgrade involved migrating from windows vCenter 5.5 to a vcsa 6.0 Update 2. I used the migration wizard for this solution. (6.0 Update 2M).
The old vCenter was running also the update manager. Meaning I had to move the update manager to a new windows server and after the vCenter was migrated I had to upgrade the update manager.
This sounds simple.
And it was ….. for a while…
I successfully moved the 5.5 update manager installation to a new windows server.
The migration to the VCSA also went successfully (loving it)
The iso for 6.0Update 2M doesn’t contain the update manager software. So I downloaded the iso for windows installation. From the same page as I downloaded the previous iso. But when I install update manager, I get the error that the vCenter server is incompatible with the update manager…. (what !!!!)
After some (soul) searching…. I found a forum thread that the Update Manager for vCenter 6.0.0b does work. (really…..)
And yes … after downloading that iso, starting the update manager installation, the upgrade was succesfull.
I only wonder… what is the difference between 6.0Update2M and the windows version. Why won’t the update manager from that iso work with the 6.0Update2M version….
If you want to migrate from a 5.5 enviroment to the latest version on 6.0 (currently update 2a), then after using the migration tool, go to the vCenter Appliance administration site and start from there the update. (https://<fqdn>:5480)
After which you can upgrade vCenter Update Manager to the latest version.
The script has been modified to exclude certain vibs. The reason is that with some configurations we found out that the wrong vib was loaded on a vspherer host. Resulting in a PSOD, due to driver, hardware, ESXi version conflicts.
With this in mind, I added the functionality to exclude VIBs. The excluded VIBs are listed in the parameters.ps1 file.
After the new image profile has been configured, the script will exclude the VIBs, if they are present. VIBs that are excluded are reported in excluded.txt file.
The script creates a parameters.ps1 file in the project folder, containing the names of the Vibs that are excluded. This file is used to re-create an image if necessary.
You can find the script at github, here
You can load PowerCLI with a one-liner again.
Why ? well… PowerCLI 6.5 is only moduled based, while the previous versions where a mix off snappins and modules.
When it was mainly snappin bassed I used a one-liner like:
get-pssnapin -registered vmware* | add-pssnappin
When PowerCLI was module and snappin based, I used a custom PowerShell function import-PowerCLI (see my previous post https://vblog.bartlievers.nl/2016/11/22/import-powercli/ for details). But with PowerCLI 6.5 R1 you can use a one-line once again.
This one-line is :
> Get-Module -ListAvailable vmware* |Import-Module
To make live a bit easier when writing powershell scripts, it is a good idea to have some kind of a script template.
By using a template you don’t have to worry about the standard stuff you always put in a script. And you can also have some customs functions already available. It is a good starting point for writing the script you want.
And it helps you to standardize you scripting. Which makes it in the end easier to maintain etc… Continue reading “Powershell script template”
For my work I use PowerCLI a lot, but I don’t like the shell that is available when installing PowerCLI. I just want to start PowerShell (mostly through PowerShell ISE) and load with one command the PowerCLI modules and/or snapins and not be limited.
Before PowerCLI 6.5, PowerCLI was a mix of powershell snappins and modules. To support older PowerCLI versions, the script will check if there are vmware powershell snappins registered. And will load them.
Powershell modules will have precedence over the snappins. Continue reading “import-PowerCLI”
Yes, it is another blog site about virtualization and related subjects. I’m not sure how often this will be updated.
My intend is to write posts about virtualization. Mostly it will have a relation with VMware and their suites (like VMware vSphere, vRealize Log Insight, PowerCLI).
