VDS_E_LUN_UPDATE_DISK
VDS_E_LUN_UPDATE_DISK is a split outcome: the array-side LUN operation completed, but VDS could not update the associated Windows disk status. The original capacity may therefore already have changed even though the management call returned an error.
Do not blindly repeat the LUN operation
- Query LUN size and status directly from the hardware provider.
- Refresh provider and service caches, then re-enumerate the local disk.
- Compare disk size, partition layout and filesystem state before any retry.
Repeating a shrink because the call returned failure can reduce capacity twice. The built-in guidance is to call refresh to retry status synchronization, not to repeat the destructive LUN change. Escalate if the provider and Windows disk continue to report different sizes.
