HPE Intel-based Gen10 Plus, Gen11 and Gen12 servers have an embedded Intel VROC storage controller that may be used for OS installation. If the OS is installed using the VROC, and the system board requires replacement, specific steps MUST be taken BOTH BEFORE and AFTER the system board is replaced to ensure the OS volume(s) are retained. If these steps are not performed, in order, the OS will not boot and will require re-installation.
This process applies to all HPE Intel-based Gen10 Plus, Gen11, and Gen12 servers using the embedded VROC for OS installation when a system board replacement is performed.
Before performing any maintenance, certain BIOS/Platform Configuration (RBSU) settings and versions need to be noted. If the server does not complete Power-On Self-Test (POST), there is no recent Active Health System (AHS), or the required information is unavailable, the following steps may not be possible to complete.1. Take note of the System ROM version and VROC driver version. Both versions can be seen on the same screen.During POST, press F9 to enter System Utilities. Navigate to System Configuration > Intel(R) VROC2. If using SATA drives with the VROC, take note of allSATA Controller Options.During POST, press F9 to enter System Utilities. Navigate to BIOS/Platform Configuration (RBSU) > Storage Options > SATA Controller Options.3. If using NVMe drives with the VROC, take note of allNVM Express Options(Intel VMD and Intel VROC)During POST press F9 to enter System Utilities. Navigate to the following BIOS/Platform Configuration (RBSU) > Storage Options > NVM Express Options > NVM Express > Intel(R) NVMe Options > Intel(R) CPU VMD Support > Enable All CPU NVMe Root Ports.Using the arrow key, move the cursor to highlight the menu option Intel(R) VROC Support. Note the license type you are using.4. Power down the server, remove power, and detach the drives the OS is installed on from the drive backplane. (The drives need to remain in the same location)---> 5. Replace system boardAfter the system board is replaced and BEFORE the drives are reinserted.6. Boot the server into RBSU.7. If the System ROM and VROC driver on the new system board does not match the replaced system board then update the firmware using your preferred method. Note the VROC driver is contained within the System ROM and will not need a separate install.8. In RBSU, confirm the VROC is enabled. If changing from AHCI mode to Intel VROC SATA Support, SAVE and reboot to continue.9. If using NVMe drives, make sure all RBSU configuration is matching the same as the NVM Express Options on the previous system board.10. After System ROM, VROC driver, and other storage settings are matching those from the previous system board, power down and remove power from the server.11. Reinsert the drives to the same location they were in prior to the system board replacement.12. Reinsert power and power on the machine.13. During POST, Press F11 to select Boot Menu.14. Select the Boot option that corresponds to the OS installed on the drives.15. The same OS installation should boot.16. Go to RBSU to change the UEFI Boot Order to match the previous configuration if needed.
