VirtualMachineManager

Adds a computer as a library server to VMM.

Syntax

Add-SCLibraryServer
   [-VMMServer <ServerConnection>]
   [-ComputerName] <String>
   -Credential <VMMCredential>
   [-Description <String>]
   [-VMHostGroup <HostGroup>]
   [-JobGroup <Guid>]
   [-EnableUnencryptedFileTransfer <Boolean>]
   [-RunAsynchronously]
   [-PROTipID <Guid>]
   [-JobVariable <String>]
   [<CommonParameters>]

Description

The Add-SCLibraryServer cmdlet adds one or more computers as library servers to Virtual Machine Manager (VMM). For a computer to be a library server, it must be in the same domain as, or in a trusted domain with, the VMM server. For VMM library server system requirements, see Preparing your environment for System Center 2019 - Virtual Machine Manager in the TechNet Library at http://go.microsoft.com/fwlink/?LinkId=799436.

When you add a computer as a library server to VMM, VMM automatically installs the Virtual Machine Manager Agent software on that server.

The VMM library is made up of two primary components:

  • Library. The portion of the VMM database that stores objects that represent all library resources.

  • Library Resource Files. Files that are stored in library shares on one or more physical library servers. Library resources can be distributed across multiple physical library servers. Some library objects have files and others do not.

VMM library resources include virtual machine templates, hardware profiles, guest operating system profiles, virtual hard disks (Windows-based .vhd files, Citrix XenServer-based .vhd files or VMware-based .vmdk files), virtual floppy disks (Windows-based .vfd files or VMware-based .flp files), ISO images (.iso files), and scripts. In addition, you can store virtual machines in the library that you do not want deployed on a host.

Of these resources, templates, hardware profiles, and guest operating system profiles are represented only by objects stored in the library. The other resources are files stored in the file system on library servers and objects that correspond to those files stored in the library.

Examples

Example 1: Add a library server

PS C:\> $Creds = Get-Credential
PS C:\> Add-SCLibraryServer -VMMServer "VMMServer01.Contoso.com" -ComputerName "LibraryServer01.Contoso.com" -Credential $Creds -RunAsynchronously

The first command prompts you for credentials. When the dialog box appears, type the user name and password for either a local Administrator account or a domain account with administrator rights on the library server.

The second command adds the library server object named LibraryServer01 to the library on VMMServer01.

Example 2: Add a highly available file server with two nodes as a library server

PS C:\> $Credential = Get-Credential
PS C:\> $Cluster = Find-SCCluster -ComputerName "HAFileServer01.Contoso.com" -Credential $Credential
PS C:\> ForEach ($Node in $Cluster.ClusterNodes) { Add-SCLibraryServer -ComputerName $Node -Credential $Credential}
PS C:\> Add-SCLibraryServer -ComputerName "HAFileServer01.Contoso.com" -Credential $Credential
PS C:\> Add-SCLibraryShare -SharePath "\\HAFileServer01.Contoso.com\LibShare" -Credential $Credential

This example assumes the following: you have created a cluster with at least two nodes, you have created a highly available file server, and you have created a share on the highly available file server (in this example, this is represented by \HAFIleServer01.Contoso.com\LibShare).

The first command uses Get-Credential to prompt you to supply a user name and password and stores your credentials in $Credential. The required credentials for this operation are a domain account with administrator rights on each node of a failover cluster hosting the highly available file server that you want to add to VMM.

The second command uses the Find-SCCluster cmdlet to confirm that HAFileServer01 is a highly available file server and stores the cluster object in the $Cluster variable.

The third command uses a ForEach loop to pass each cluster node to Add-SCLibraryServer, which adds the nodes as library servers. For more information about the Windows PowerShell ForEach loop statement, type Get-Help about_ForEach.

The fourth command uses Add-SCLibraryServer to add the highly available file server named HAFileServer01 to VMM as a library server.

The last command uses Add-SCLibraryShare to add the specified share on the highly available file server. For more information about adding library shares, type Get-Help Add-SCLibraryShare.

Parameters

-ComputerName

Specifies the name of a computer that VMM can uniquely identify on your network. The acceptable values for this parameter are:

  • FQDN
  • IPv4 or IPv6 address
  • NetBIOS name
Type:String
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Credential

Specifies a credential object or, for some cmdlets, a Run As account object that contains the user name and password of an account that has permission to perform this action. Or, in the case of Restart-SCJob, has permission to complete a restarted task.

For more information about the PSCredential object, type Get-Help Get-Credential.

For more information about Run As accounts, type Get-Help New-SCRunAsAccount.

Type:VMMCredential
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-Description

Specifies a description for the library server.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-EnableUnencryptedFileTransfer

Indicates, when set to True, that network file transfers do not require encryption. Allowing unencrypted network file transfers can improve performance if neither the source host nor the destination host requires encryption.

Use this parameter to:

  • Enable unencrypted file transfers into, or out of, the library.
  • Enable unencrypted file transfers into, out of, or within a host group.
Type:Boolean
Aliases:AllowUnencryptedTransfers
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-JobGroup

Specifies an identifier for a series of commands that will run as a set just before the final command that includes the same job group identifier runs.

Type:Guid
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-JobVariable

Specifies that job progress is tracked and stored in the variable named by this parameter.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-PROTipID

Specifies the ID of the Performance and Resource Optimization tip (PRO tip) that triggered this action. This parameter lets you audit PRO tips.

Type:Guid
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-RunAsynchronously

Indicates that the job runs asynchronously so that control returns to the command shell immediately.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-VMHostGroup

Specifies a virtual machine host group object.

Type:HostGroup
Aliases:LibraryGroup
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-VMMServer

Specifies a VMM server object.

Type:ServerConnection
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

Outputs

LibraryServer

This cmdlet returns a LibraryServer object.
