Known Issues with the Intel® Virtual RAID on CPU (Intel® VROC) 9.3 Release for Windows*

The following information lists the known issues with the Intel® VROC 9.3 release for Windows*. To learn about the latest updates of Intel® VROC for Windows*, refer to the Intel® Virtual RAID on CPU (Intel® VROC) Release Notes for Windows*.

Issue ID	Description
14015389340	When using AtaPassThru protocol to get information on attached devices from the Intel® VROC Pre-OS, the value of GetNextTargetLun may not be successful.
15010088464	When the SATA controller is switched to RAID mode, SATA drive information will be displayed in the Intel® VROC SATA HII instead. So users can reference the device information in the Intel® VROC SATA HII.
15011986293	When booting the platform with a degraded Intel® VROC RAID 1 data volume, the Intel® VROC 8.0 Graphical User Interface (GUI) utility may not properly display the RAID volume.
15012192390	An Intel® VROC SATA HDD may have a problem unlocking after sending the 0xf2 command.
15013821671	The Intel® VROC Graphical User Interface (GUI) utility did not show the rebuilding event as the disk is hot-plugged and inserted when a RAID member is only 100MB.
15016690395	Customers running Intel® VROC under a Microsoft Windows* environment, using Gen5 NVMe* SSDs, may not see the expected performance benefits when running in a RAID 0 configuration. Customers generally utilize a RAID 0 configuration to achieve (and expect to see) a linear scaling of the aggregate bandwidth of the RAID member drives. Running in this configuration, customers may see approximately 60% of that value.
15017580021	Due to potential changes made by Microsoft in the new Windows* installer introduced with Windows* 2025, there is a possibility issue where the Intel® VROC NVMe RAID volume may not be recognized after loading the F6 driver during the Windows* 2025 operating system installation. This issue can occur with any Windows* 2025 build, regardless of the Intel® VROC driver version or the specific version of Windows* 2025. The current workaround is to click "Refresh" five to ten seconds after initially loading the Intel® VROC driver.
18012869559	The Intel® VROC Graphical User Interface (GUI) and Command-Line Interface (CLI) utilities may not forbid performing operations that use self-encrypting drives in the locked state. Creating RAID volumes with locked members may result in a failed volume state.
18015334984	The warning message: Warning: The AHCI driver will be updated to the latest Microsoft AHCI driver in the system does not occur when installing Intel® VROC in AHCI mode using the installer.
18016767645	18016767645 Within the Intel® VROC SED Manager, a physical drive may appear twice.
18020541368	While within the Intel® VROC SED Manager, unencrypted drives that are unplugged and then selected to have a security key set up may experience a platform hang.
18022812016	When the operating system performs a TRIM command onto an Intel® VROC RAID 1 or RAID 10 volume comprised of drives that perform TRIM activities in different ways may encounter a data inconsistency on those areas that had been TRIMed.
18029487344	Intel® VROC operating system interfaces (Windows* GUI & CLI, Linux* mdadm, Linux*/Windows* OOB) may not forbid performing operations that use self-encrypting drives in locked/foreign state. RAID volume operations with locked/foreign devices will be failed (such as RAID volume creation will be failed).
18037794909	The installation may unexpectedly start with the flag -ver and additional parameter during the Intel® VROC Graphical User Interface (GUI) installation process.
18040635664	Certain platforms may not reboot as expected after product installation using the parameters -s -b during the Intel® VROC Graphical User Interface (GUI) installation process.
