How to Get Path Selection Policy of Physical RDM LUN by PowerCLI

It's frustration to check RDM information, you have to check across  all ESXi hosts to make sure configuration is aligned. I just figured out two line commands to get path selection policy (aka PSP).

[do_widget "Language Switcher" wrap=aside title=false]

$VM  = Get-hardDisk -VM [VM name] -DiskType RawPhysical

$VM | select ScsiCanonicalName | foreach {Get-Cluster -Name [Cluster name] | Get-VMHost | Get-ScsiLun -CanonicalName
$_.ScsiCanonicalName} | select CanonicalName,CapacityGB,MultipathPolicy,VMHost | Format-Table -AutoSize

You should replace [VM name] & [Cluster name] by your own value.

Run these commands on PowerCLI it gives back PSP of RDM LUNs with LUN NAA and ESXi host name. As you may know ESXi 5.5 supports PSP "Round Robin" instead of Fixed for physical RDM LUNs, you may also want to change the PSP after upgrading to ESXi 5.5, please read How to retrieve or set Path Selection Policy by vCLI to learn how to set PSP in batch.

Connect-NsxtServer shows "Unable to connect to the remote server"

When you run Connect-NsxtServer in the PowerCLI, it may show "Unable to connect to the remote server".  Because the error message is a little bit confusing with other login issues. It's not easy to troubleshoot. The actual reason is the NSX-T uses a self-signed certificate, and the PowerCLI cannot accept the certificate automatically. The fix is super easy. You need to set the PowerCLI to ignore the invalid certificate with the following command: Set-PowerCLIConfiguration -Scope User -InvalidCertificateAction:Ignore -Confirm:$false

Setup Terraform and Ansible for Windows provisionon CentOS

Provisioning Windows machines with Terraform is easy. Configuring Windows machines with Ansible is also not complex. However, it's a little bit challenging to combine them. The following steps are some ideas about handling a Windows machine from provisioning to post configuration without modifying the winrm configuration on the guest operating system. Install required repos for yum. yum -y install yum -y install yum -y install yum -y install epel-release yum -y install yum-utils yum-config-manager --add-repo Install  Terraform . sudo yum -y install terraform Install  Ansible . sudo yum -y install ansible Install  Kerberos . yum -y install gcc python-devel krb5-devel krb5-libs krb5-workstation

How to List All Users in Terraform Cloud

Terraform has a rich API. However, the API documentation does not mention how to list all users. We can leverage the organization membership API and the PowerShell command  Invoke-RestMethod  to get a user list. 1. Create an organization token in Terraform Cloud. 2. Create the token variable ( $Token ) in PowerShell. $Token = "abcde" 3. Create the API parameters variable in PowerShell. $params = @{ Uri = "" Authentication = "Bearer" Token = $Token ContentType = "application/vnd.api+json" } Note: You need to replace ZHENGWU with your own organization name. And I used 100 at the end of the URI to retrieve the first 100 users. It can be any number.  4. Retrieve the API return and list the user's email address. $Test = Invoke-RestMethod @params $
