Intel VROC operates directly on the PCIe lanes of modern enterprise processors utilizing Intel Volume Management Device (VMD). Its exceptions are logged into the Windows Event Viewer via the
IAStorDataMgrSvc engine or passed to out-of-band server logs.unset Event ID 4107/unset Event ID 4108(S.M.A.R.T. Threshold Exceeded):- Context: The controller intercepted an internal telemetry alert from an NVMe SSD stating that a reliability threshold (such as critical temperature, spare blocks remaining, or device lifetime percentage) has broken safe operating bounds.
- Action Plan: Back up the filesystem immediately. Even though the array remains green, the SSD controller is warning of imminent physical degradation. Schedule a hot-swap replacement.
unset "Incompatible State"(Volume Management Alert):- Context: The array was moved into a different motherboard slot/CPU domain that does not natively support the selected configuration, or the physical VROC hardware protection key (upgrade module plugged into the motherboard) is broken, missing, or mismatched.
- Action Plan: Validate the licensing profile of the server platform. If migrating arrays across hosts, confirm that the target VMD BIOS rules match the original system topology.
unset Event ID 4153(Data Volume Migration Aborted):- Context: A RAID expansion or level migration failed mid-cycle due to an unrecoverable resource bottleneck, improper
.NETruntime framework drops, or a sudden I/O timeout. - Action Plan: Keep the system completely powered on. Abruptly restarting the system during a migration failure risks freezing the array into a permanently broken state. Run command line diagnostics to isolate the stalled LBA range.
