Set-SCVirtualScsiAdapter

Changes properties of a virtual SCSI adapter used in VMM.

Syntax

Set-SCVirtualScsiAdapter [-VirtualScsiAdapter] <VirtualSCSIAdapter> [-AdapterID <Byte>] [-JobGroup <Guid>]
 [-JobVariable <String>] [-OnBehalfOfUser <String>] [-OnBehalfOfUserRole <UserRole>] [-PROTipID <Guid>]
 [-RunAsynchronously] [-ScsiControllerType <VMSCSIControllerType>] [-ShareVirtualScsiAdapter <Boolean>]
 [<CommonParameters>]

Description

The Set-SCVirtualScsiAdapter cmdlet changes one or more properties of a virtual SCSI adapter used in a Virtual Machine Manager (VMM) environment. Settings that you can modify include specifying whether or not a virtual SCSI adapter is shared and setting the adapter ID.

Note: Using the ShareVirtualScsiAdapter parameter to share a virtual SCSI adapter on a virtual machine in order to enable guest clustering is supported only if the virtual machine is deployed on a VMware ESX host. The SharedVirtualScsiAdapter parameter is not used for a virtual machine on a Hyper-V host because a virtual machine on a Hyper-V host uses iSCSI for shared storage.

Note: Set-SCVirtualScsiAdapter is not used for Citrix XenServer hosts because the SCSI adapter on Citrix XenServer virtual machines is not configurable.

Examples

Example 1: Share a specific virtual SCSI adapter on a virtual machine to enable it for guest clustering

PS C:\> $VM = Get-SCVirtualMachine -Name "VM01"
PS C:\> $Adapter = Get-SCVirtualScsiAdapter -VM $VM 
PS C:\> Set-SCVirtualSCSIAdapter -VirtualScsiAdapter $Adapter -ShareVirtualScsiAdapter $True

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

The second command gets the SCSI adapter object on VM01 and stores the object in the $Adapter variable. This example assumes that VM01 has one virtual SCSI adapter. However, a virtual machine can have up to four virtual SCSI adapters attached.

The last command enables the virtual SCSI adapter object stored in $Adapter and specifies that is it shared so that it can be used in guest clustering.

Note: Using the Shared parameter to share a virtual SCSI adapter on a virtual machine is supported only if the virtual machine is deployed on an ESX host. The Shared parameter is not used for a virtual machine a Hyper-V host because a virtual machine on a Hyper-V host uses iSCSI for shared storage. The Shared parameter is also not used for a virtual machine on a XenServer host because XenServer-based virtual machines always have exactly one SCSI adapter.

Parameters

-AdapterID

Specifies the logical unit number, or LUN ID. Hyper-V and XenServer do not expose this value, and it cannot be changed. For a VMware ESX host, the default is 7 and cannot be changed.

Type:Byte
Required:False
Position:Named
Default value:None
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
Required:False
Position:Named
Default value:None
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
Required:False
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-OnBehalfOfUser

Specifies the name of a user. This cmdlet sets the on behalf of user as the user that this parameter specifies.

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

Specifies a user role. This cmdlet sets the on behalf of user role as the user role that this parameter specifies. To obtain a user role object, use the Get-SCUserRole cmdlet.

Type:UserRole
Required:False
Position:Named
Default value:None
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
Required:False
Position:Named
Default value:None
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
Required:False
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ScsiControllerType

Specifies a SCSI controller type. Valid values are:

- DefaultType

  • NoType
  • LsiLogic
  • BusLogic
  • ParaVirtualSCSI
  • LsiLogicSAS

Type:VMSCSIControllerType
Parameter Sets:DefaultTypeNoType, LsiLogic, BusLogic, ParaVirtualSCSI, LsiLogicSAS
Required:False
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ShareVirtualScsiAdapter

Indicates whether a virtual SCSI adapter is shared so that it can be used in guest clustering.

Type of Host: Hyper-V host Uses This Parameter:

- Hyper-V host: No (for guest clustering, use iSCSI storage)

  • XenServer host: No (Xen VMs always have exactly one SCSI adapter)

    Note: When sharing a SCSI controller on a virtual machine on an ESX host, VMM defaults the SCSI sharing policy on VMware to "physical."

Type:Boolean
Aliases:Shared
Required:False
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-VirtualScsiAdapter

Specifies a virtual SCSI adapter object for a virtual machine.

Type of Host Number of Virtual SCSI Adapters

Hyper-V: Up to four synthetic virtual SCSI adapters per VM, and up to 64 devices per adapter. Supports a virtual disk drive size up to 2040 GB. Does not support emulated virtual SCSI adapters. VMware ESX: Up to four virtual SCSI adapters per VM, and up to 15 devices per adapter. Supports a virtual disk drive size up to 2048 GB. Citrix XenServer: Always one virtual SCSI adapter per VM, and up to eight devices per adapter. Supports a virtual disk drive size up to 2048 GB.

Type:VirtualSCSIAdapter
Required:True
Position:0
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False

Outputs

VirtualSCSIAdapter

This cmdlet returns a **VirtualScsiAdapter** object.

Notes

* Requires a VMM virtual SCSI adapter object, which can be retrieved by using the **Get-SCVirtualScsiAdapter** cmdlet.
