Step 1. Running Cluster Validation Tool
Run the cluster validation tool to make sure server nodes are configured correctly
to create a cluster using Storage Spaces Direct.
Issue the following PowerShell command to validate a set of servers for use as
Storage Spaces Direct cluster:
Test-Cluster -Node <MachineName1, MachineName2, MachineName3,
MachineName4> -Include "Storage Spaces Direct", Inventory,
Network, "System Configuration"
Step 2. Creating a Cluster
Create a cluster with the four nodes (which was validated for cluster creation) in
Step 1. Running Cluster Validation Tool
To create a cluster, issue the following PowerShell command.
New-Cluster -Name <ClusterName> -Node <MachineName1, MachineName2,
MachineName3, MachineName4> -NoStorage
The
–NoStorage
parameter is required. If it is not included, the disks are
automatically added to the cluster, and you must remove them before enabling
Storage Spaces Direct. Otherwise, they will not be included in the Storage Spaces
Direct storage pool.
Step 3. Configuring a Cluster Witness
QLogic recommends that you configure a witness for the cluster, so that this
four-node system can withstand two nodes failing or being offline. With these
systems, you can configure file share witness or cloud witness.

Step 4. Cleaning Disks Used for Storage Spaces Direct
The disks intended to be used for Storage Spaces Direct must be empty, and
without partitions or other data. If a disk has partitions or other data, it will not be
included in the Storage Spaces Direct system.
The following PowerShell command can be placed in a PowerShell script (
.PS1
)
file and executed from the management system in an open PowerShell (or
PowerShell ISE) console with Administrator privileges.
NOTE
Running this script helps identify the disks on each node that can be used
for Storage Spaces Direct and removes all data and partitions from those
disks.
