.SYNOPSIS
   Keep PVS vDisks and versioning consistent across multiple PVS sites and additional PVS farms
.DESCRIPTION
   Checks for vDisks and versioning and will export XML if required.  Script will then robocopy all vDisk files out to all PVS servers.  Once copied script will import and set versioning to match local server.

.PARAMETER PVSServers
   PVS Server hostnames that have access to additonal farms.
.PARAMETER StorePath
   Local Disk Store Path (same path must exist on all servers)
.PARAMETER NoCopy
    Doesn't copy any files to other servers.
.PARAMETER DISK
    Specific Disk to copy and import
.PARAMETER JUSTADMIN
    Copies and imports to only admin servers listed
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore"
   Copies and imports disks and versions to all PVS farm servers accessible via localhost and uses the vDisk store at "E:\teststore" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -Site "MySite" -Disk "MYDISK"
   Copies and imports "MYDISK" ONLY to all servers in "MYSITE"
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -Site "MySite" -PVSServers "PVSFARM01" -JUSTADMIN
   Copies and imports disks and versions from MYSITE to PVSFARM01 server ONLY. (Images must be replicated from PVSFARM01)
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -PVSServers "PVSFARM01","PVSFARM02"
   Copies and imports disks and versions to all PVS farm servers accessible via localhost, PVSFARM01, PVSFARM02 and uses the vDisk store at "E:\teststore" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -PVSServers "PVSFARM01","PVSFARM02" -Site "General"
   Copies and imports disks and versions to all PVS farm servers in 'General' site accessible via localhost, PVSFARM01, PVSFARM02 and uses the vDisk store at "E:\teststore" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore","E:\teststore2" -PVSServers "PVSFARM01","PVSFARM02"
   Copies and imports disk versions to all PVS farm servers accessible via localhost, PVSFARM01, PVSFARM02 and uses the vDisk store at "E:\teststore" and "E:\teststore2" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -nocopy
   Imports disks and versions on all PVS farm servers accessible via localhost for each server.  Does not perform any robocopy

.SYNOPSIS
   Keep PVS vDisks and versioning consistent across multiple PVS sites and additional PVS farms
.DESCRIPTION
   Checks for vDisks and versioning and will export XML if required.  Script will then robocopy all vDisk files out to all PVS servers.  Once copied script will import and set versioning to match local server.

.PARAMETER PVSServers
   PVS Server hostnames that have access to additonal farms.
.PARAMETER StorePath
   Local Disk Store Path (same path must exist on all servers)
.PARAMETER NoCopy
    Doesn't copy any files to other servers.
.PARAMETER DISK
    Specific Disk to copy and import
.PARAMETER JUSTADMIN
    Copies and imports to only admin servers listed
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore"
   Copies and imports disks and versions to all PVS farm servers accessible via localhost and uses the vDisk store at "E:\teststore" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -Site "MySite" -Disk "MYDISK"
   Copies and imports "MYDISK" ONLY to all servers in "MYSITE"
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -Site "MySite" -PVSServers "PVSFARM01" -JUSTADMIN
   Copies and imports disks and versions from MYSITE to PVSFARM01 server ONLY. (Images must be replicated from PVSFARM01)
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -PVSServers "PVSFARM01","PVSFARM02"
   Copies and imports disks and versions to all PVS farm servers accessible via localhost, PVSFARM01, PVSFARM02 and uses the vDisk store at "E:\teststore" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore" -PVSServers "PVSFARM01","PVSFARM02" -Site "General"
   Copies and imports disks and versions to all PVS farm servers in 'General' site accessible via localhost, PVSFARM01, PVSFARM02 and uses the vDisk store at "E:\teststore" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -StorePath "E:\teststore","E:\teststore2" -PVSServers "PVSFARM01","PVSFARM02"
   Copies and imports disk versions to all PVS farm servers accessible via localhost, PVSFARM01, PVSFARM02 and uses the vDisk store at "E:\teststore" and "E:\teststore2" for robocopy.
.EXAMPLE
   .\PVSReplicate.ps1 -nocopy
   Imports disks and versions on all PVS farm servers accessible via localhost for each server.  Does not perform any robocopy
