PowerCLI - How to backup VCSA 6.5

I have recently been working on an issue with a PowerCLI script that has been working for a few weeks that just stopped working. The script is modified version of the one Kyle Ruddy posted about here:
https://blogs.vmware.com/PowerCLI/2018/07/automate-file-based-backup-of-vcsa.html

The script also uses Credentials store to be able to run the script securely but other than that the script is pretty vanilla.

Now that you are up to speed with how it is supposed to work, my next post will cover the issue, and how to resolve it.

PowerCLI - Datastore Report

I recently was working in an environment where they are still running vSphere 6.0. While doing some storage expansions I discovered that the Flash Client and the C# Client were not reporting the same size on the Datastore. This can be very frustrating as you are not sure which one you can trust. So as a tie breaker I decided to turn to my good friend PowerCLI.

It turns out that the PowerCLI and the C# client were reporting the same thing. So I decided to create a PowerCLI Script to assist me in my work. You can find the script there on my Github:

PowerCLI - Virtual Host Hardware Information

I have recently been working on a asset inventory issue where I was provided a list of serial numbers from our hardware vendor and I was asked to reconcile it with what we had. Well that is easier said than done in most cases.

I know that vCenter collects a bunch of hardware information and I wanted to see if there was a way to pull the Serial number that is on the System board and put that information into a .csv.

In comes the following command:

 Get-VMHost | Get-VMHostHardware -SkipAllSslCertificateChecks | Export-Csv C:\temp\VMHostHardware.csv

This command will pull all the hardware information that vCenter records and puts it to a .CSV.

I will do my best to update this post with an example of what the results will look like.

PowerCLI - vSphere Role Privilege report

So I have been looking for ways to expand my knowledge with PowerCLI. This whole effort came about from going to VMWorld 2019 in San Francisco and seeing presentations by Kyle Ruddy and Luc Denkens. Let me tell you, they did some amazing things in their presentations. 

I had been working on a project where I needed to get list of all of the Non-Standard vCenter Roles along with the privileges assigned to those roles. I am still very new to this whole PowerCLI thing, but my google skills are top notch. I found a blog post on this blog http://kunaludapi.blogspot.com/

I ran the script to see how well it worked and it worked as advertised. I created a copy of the script on my Github which you can find here: https://github.com/kenbshinn/PowerCLI-Scripts/blob/master/vSphere_Role_Report.ps1

How to unlock and reset SSO password in vSphere 6.x (2146224)

So I have a bit of a embarrassing confession to make. I forgot to record the Administrator password for my VCSA Appliance. Total disclosure, I was freaking out and I really thought I was going to have to start from scratch. I did some research I was surprised to find out that you can actually reset the Administrator account on a VCSA appliance as long as you have the root password for the appliance and you have access to the VCSA Console. Below are a list of the links to the KB Articles from VMware.

Resetting SSO Administrator - VCSA 6.x

Below is the PUTTY session as an example.

shinnk@Computer:~$ ssh root@devvcsa01.xxxx.xxxxx
ssh: Could not resolve hostname devvcsa01.xxx.xxxxx: Name or service not known
shinnk@Computer:~$ ssh root@172.26.44.18

Are you sure you want to continue connecting (yes/no)? yes

7. Get vmdir log level and mask
==================

==================
Please select:
0. exit
1. Test LDAP connectivity
2. Force start replication cycle
3. Reset account password
4. Set log level and mask
5. Set vmdir state
6. Get vmdir state
7. Get vmdir log level and mask
==================

Once you go through all these steps you are now able to log into VCSA with that temporary password that you are given and you are also able to reset it as well.

Getting past Certificate issue in Power CLI

So I recently started working more with PowerCLI. After my time at VMWorld 2019 (which I will cover in another post) I realized how powerful that PowerCLI actually is (pun not intended). In starting to work with PowerCLI I came across the following message whil: trying to connect to my vCenter

Connect-vIServer : xx-x-xxxx xx:xx:xx Connect-VIServer Error: Invalid server certificate. Use Set-PowerCLIConfiguration to set the value for the InvalidCertificateAction option to Prompt if you’d like to connect once or to add a permanent exception for this server.

I did some googling and I found this article,so shout out to Ivo Beerens for his article.

https://www.ivobeerens.nl/2018/07/18/quick-tip-powercli-invalid-server-certificate-error/

In his article he goes on to share this command

Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false

After putting that into PowerShell and pressing enter you will no longer get the Invalid Certificate message.

I hope you found this post helpful, I will be posting about some of the scripts that I have been posting on my Github. Please share with your friends if you found this helpful.
