An existing 4-node VxRail standard cluster has to be scaled out with 2 additional nodes...

To create the required vSAN storage policy in the vSphere Client for a VxRail stretched cluster, follow these steps:

Log in to vSphere Client:

Open the vSphere Client.

Enter the username: administrator@vsphere.local.

Enter the password: VMw@r3!123.

Click Login.

Navigate to Storage Policies:

From the home screen, go to Policies and Profiles in the left-hand navigation pane.

Click on VM Storage Policies.

Create a New Storage Policy:

Click Create VM Storage Policy.

Enter the name as vSAN Stretched Cluster.

Click Next.

Configure Policy Rules:

In the Policy Structure section, choose Enable tag-based placement rules if needed.

Click Next.

Add vSAN Rules:

In the Storage Compatibility section, click Add rule and select vSAN.

Configure the following:

Primary level of failures to tolerate (PFTT): 1 failure - RAID 1 (Mirroring)

Secondary level of failures to tolerate (SFTT): 1 failure - RAID 1 (Mirroring)

Failures to Tolerate: 1

Provisioning type: Thick Provisioning

Ensure "Force Provisioning" is enabled. This allows the VM to be provisioned even if the current resources do not satisfy the policy.

Set Data Services:

Skip the Data Services section if not applicable.

Click Next.

Review and Finish:

Review the policy settings.

Click Finish to create the storage policy.

Apply the Storage Policy to VMs:
