Detailed Description

The Show-VirtualDisk cmdlet makes a virtual disk available to a host (by initiator and target ports). This cmdlet is equivalent to a VDS unmask operation.

Parameters

-AsJob

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Aliases	Session
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-FriendlyName<String[]>

Specifies the friendly name of the virtual disk to make available to the specified hosts.

Aliases	none
Required?	true
Position?	1
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-HostType<HostType>

Specifies the operating system of the host computer.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-InitiatorAddress<String>

Specifies the address for an initiator to which the virtual disk should be unmasked.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-InputObject<CimInstance[]>

Accepts an object from the pipeline as input.

Aliases	none
Required?	true
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByValue)
Accept Wildcard Characters?	false

-Name<String[]>

Specifies the name of the virtual disk to make available to the specified hosts.

Aliases	none
Required?	true
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-PassThru

Specifies that the cmdlet should output an object representing the virtual disk it unmasked. By default, this cmdlet does not generate any output.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-TargetPortAddresses<String[]>

Specifies one or more target port addresses to which the virtual disk should be unmasked.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-UniqueId<String[]>

Specifies the UniqueID of the virtual disk to make available to the specified host.

Aliases	Id
Required?	true
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-Confirm

Prompts you for confirmation before running the cmdlet.

Required?	false
Position?	named
Default Value	false
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Required?	false
Position?	named
Default Value	false
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_VirtualDisk

You can pipe an MSFT_VirtualDisk object to the InputObject parameter.

Outputs

The output type is the type of the objects that the cmdlet emits.

Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_VirtualDisk

If you specify the Passthru parameter, this cmdlet outputs an object representing the virtual disk you made available to a host computer.

Notes

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Examples

Example 1: Make a virtual disk available to the local computer

This example makes the "SQLData_27a" virtual disk available to all initiators and target ports of the local computer.

PS C:\> $initaddress = (Get-InitiatorPort)

PS C:\> $tarport = (Get-TargetPort)

PS C:\> Show-VirtualDisk -FriendlyName "SQLData_27a" -TargetPortAddresses $tarport.NodeAddress -InitiatorAddress $initaddress.NodeAddress
