If the volumes need to be visible to a cluster of Windows Server hosts then they need to be connected to a Host Group. The following steps show how to create a Host Group, add a Host and then connect the volume to the Host Group.
PS C:\> New-PfaHostGroup -Array $f -Hosts 'SERVER01' -Name 'HOSTGROUP1'
PS C:\> New-PfaHostGroupVolumeConnection -Array $FlashArray -VolumeName 'SDK-Sample' -HostGroupName 'HOSTGROUP1'
