Properties

Properties

The Msvm_GuestClusterInformation class has these properties.

ClusterId

Data type: string
Access type: Read-only

The identifier of the failover cluster the VM's guest Operating System is a part of.

ClusterSize

Data type: uint16

Number of nodes in the cluster the VM's guest Operating System is a part of.

IsActiveActive

Data type: boolean array
Access type: Read-only

An array of booleans corresponding to each shared virtual hard disk indicating if the corresponding disk resource in the guest cluster is online.

IsOwned

Data type: boolean array
Access type: Read-only
Qualifiers: ArrayType ("Indexed")

An array of booleans corresponding to each shared virtual hard disk indicating if the corresponding disk resource in the guest cluster is currenly owned by this VM.

LastResourceMoveTime

Data type: uint64
Access type: Read-only

The clock tick count when one of the shared disk resources last moved.

Note

This property was added in Windows 10, version 1703 and Windows Server 2016.

SharedVirtualHardDiskPaths

Data type: string array
Access type: Read-only
Qualifiers: ArrayType ("Indexed")

An array of shared virtual hard disk paths connected to the VM.

SharedVirtualHardDisks

Data type: string array
Access type: Read-only
Qualifiers: ArrayType ("Indexed")
