The required parameters of the Remove-Datastore cmdlet are -Datastore and -VMHost.

In the next example, we will remove the Cluster01_Vmfs01 datastore, which we created at the beginning of this chapter:

PowerCLI C:\> Remove-Datastore -Datastore Cluster01_Vmfs01 -VMHost 192.168.0.133 -Confirm:$false

If you try to remove a datastore, it is possible that you get an error message similar to the following error message:

Before you can remove a datastore, there are some requirements that must be fulfilled:

  • There must be no virtual machines residing on the datastore

  • The datastore must not be...
