Resize-IscsiVirtualDisk

Resizes an iSCSI virtual disk.

Syntax

Parameter Set: Path
Resize-IscsiVirtualDisk [-Path] <String> [-Size] <UInt64> [-ComputerName <String> ] [-Credential <PSCredential> ] [-PassThru] [ <CommonParameters>]

Parameter Set: InputObject
Resize-IscsiVirtualDisk [-Size] <UInt64> -InputObject <IscsiVirtualDisk> [-ComputerName <String> ] [-Credential <PSCredential> ] [-PassThru] [ <CommonParameters>]




Detailed Description

The Resize-IscsiVirtualDisk cmdlet resizes a virtual disk either by expanding or compacting an existing virtual disk. Virtual disks that use the VHDX format can remain online while the cmdlet resizes them. If the cmdlet resizes an online disk, when the virtual disk is mapped to an iSCSI Target, initiators can continue to access the virtual disk even while the cmdlet resizes it. However, an initiator will not automatically see the resized virtual disk. To get access to the capacity of the expanded virtual disk, the initiator must use the Resize-Partition cmdlet to modify the volume hosted on the virtual disk.

This cmdlet can compact a disk only when the logical unit number (LUN) on the initiator side created some partitions on the LUN, and the compacting process simply shrinks the unallocated part of the LUN.

Parameters

-ComputerName<String>

Specifies the computer name, or IP address, of the remote computer, if this cmdlet is run on a remote computer.

Specifies the cluster resource group network name, or cluster node name, if this cmdlet is run on a cluster configuration.

If you do not specify a value for this parameter, the cmdlet uses the local computer.
