Get-SCLibraryRating

Calculates the placement rating of library servers to determine whether a SAN transfer can be used to transfer a virtual machine from a host to the library.

Description

The Get-SCLIbraryRating cmdlet calculates the placement rating of library servers managed by System Center Virtual Machine Manager (VMM). Specifically, this rating indicates whether VMM can use SAN transfer to transfer a particular virtual machine from a host server to a library server. If a SAN transfer is not possible, you can use a LAN transfer to store the virtual machine in the library.

For information about how to store a virtual machine in the Virtual Machine Manager library, type "Get-Help Save-SCVirtualMachine -detailed".

Parameters

LibraryServer

Required? true
Accept Pipeline Input? true (ByValue)
Position? named 
Specifies a VMM library server object.

VM

Required? false
Accept Pipeline Input? true (ByValue)
Position? named 
Specifies a virtual machine object.

VMMServer

Required? false
Accept Pipeline Input? false
Position? named 
Specifies a VMM server object.

Examples

1: Determine whether you can use a SAN transfer to store a virtual machine on the specified library server. 
PS C:\> $VM = Get-SCVirtualMachine -Name "VM01"
PS C:\> $LibServer = Get-SCLibraryServer -ComputerName "LibraryServer01.Contoso.com" 
PS C:\> $LibRating = Get-SCLibraryRating -LibraryServer $LibServer -VM $VM
PS C:\> $LibRating

The first command gets the virtual machine object named VM01 and stores the object in the $VM variable.

The second command gets the library server object named LibraryServer01 and stores the object in the $LibServer variable.

The third command gets the placement rating for LibraryServer01 (which indicates whether VMM can use a SAN transfer to transfer VM01 to LibraryServer01) and stores the rating object in the $LibRating variable.

The last command displays the rating stored in $LibRating to the user.

TIP: If a SAN transfer is not possible, you can use a LAN transfer to store the virtual machine in the library.
2: Get placement ratings for each available library server. 
PS C:\> $VM = Get-SCVirtualMachine -Name "VM01"
PS C:\> $LibServer = Get-SCLibraryServer 
PS C:\> $LibRating = Get-SCLibraryRating -LibraryServer $LibServer -VM $VM
PS C:\> $LibRating

The first command gets the virtual machine object named VM01 and stores the object in the $VM variable.

The second command gets all library server objects that are  managed by VMM and stores the objects in the $LibServer array.

The fourth command returns the placement rating for each library server object in $LibServer (which indicates whether VMM can use a SAN transfer to transfer VM01 to each of the library servers) and stores the rating for each library server object in the $LibRating array.

The last command displays the rating information for each library object to the user.

TIP: If a SAN transfer is not possible, you can use a LAN transfer to store the virtual machine in the library.
