# Create VMFS Datastore Using PowerCLI

For upcoming testing there was a need to create 140 datastores on a cluster for testing. Who wants to do that much clicking and typing? Not me! You can use the below PowerCLI commands to get the SCSI ID’s,  Create the Datastore and then Rescan all hosts in the cluster.

## How do i get the CanonicalName for allocated disks?
