STATUS_VHD_INVALID_STATE
The disk state violates an operation precondition
STATUS_VHD_INVALID_STATE identifies a lifecycle mismatch rather than a corrupt VHDX structure. Virtual-disk operations have different requirements for attachment, read-only access, write access, parent configuration, and active use by a VM or another management component.
An operation that edits relationship or metadata information must not be treated as harmless while the image is attached or in active use. Microsoft documents, for example, that changing parent information through SetVirtualDiskInformation cannot be done while the virtual disk is attached. The correct repair is to restore the documented state precondition, not to force a file-level edit.
What to verify
- Log whether the disk is attached, read-only, permanently attached, or presented to a VM, together with the handle access requested by the caller.
- Identify the owner before detaching or taking the disk offline; backup, checkpoint, and VM operations can also hold relevant state.
- Repeat the operation only after its documented state requirements are met and no longer changing.
