PowerEdge R740 Internal UEFI Driver Error

To troubleshoot and resolve problems with the Avago EFI SAS driver(such as the “Unhealthy Status” error), you can follow these expert-recommended steps drawn from Dell, Huawei, Supermicro, and Lenovo server guides and user reports:

1. Diagnose and Identify Faulty Drives:

   • Physically inspect drives showing error indicators (e.g., blinking orange/green LEDs).

   • Remove suspected drives and re-seat them carefully. Check drive health using built-in server diagnostics accessible via BIOS, iDRAC, or RAID controller tools. Look for failing drives or missing disks in RAID arrays.

   • If drives are faulty, replace them and rebuild the RAID as needed, backing up data beforehand.

2. Check Driver Health in BIOS/UEFI:

   • Enter the BIOS setup, navigate to Advanced > Driver Health > AVAGO EFI SAS Driver, and press Enter to view detailed driver and controller status.

   • If messages like “some drivers are not healthy” or “missing disks” appear, follow the on-screen instructions to repair or identify the RAID controller and drive issues. You may need to confirm prompts by entering ‘C’ or ‘Y’ to confirm configuration recognition after replacement.

3. Inspect and Reinstall RAID Controller Card:

   • Power off the server, remove, and re-seat the RAID controller card securely.

   • If that doesn’t resolve the issue, test with a known-good RAID controller card or replace the card if errors persist.

   • Ensure the firmware version of the RAID controller matches recommended versions and apply firmware updates if available.

4. Ensure Correct RAID Configuration and Boot Order:

   • Using the RAID controller’s BIOS or configuration utility, verify that RAID arrays are intact and all disks are recognised.

   • Confirm or restore the correct first boot device in BIOS so the system boots from the logical drive managed by the RAID controller.

5. Clear Cache and Resolve Hardware Failures:

   • Some reports reference “L2/L3 Cache Errors” or battery/memory faults which can cause unhealthy driver status; investigate and address these hardware-level errors.

6. Escape Boot Loops and Update Driver Settings:

   • If you’re stuck in a boot loop or cannot access usual BIOS options due to the Avago EFI SAS driver error, try removing additional cards (like network or expansion cards) that may cause conflicts.

   • Disabling certain Option ROMs or manually entering the Driver Health menu to clear errors may help break boot cycles.

7. Backup Your Data First:

   • Before making hardware changes or reconstructing RAID, ensure you have a recent backup of all critical data to mitigate loss.

8. Contact Technical Support:

   • If these steps don't resolve the issue, or if the RAID controller card or drives continue to show faults, escalate to Dell, Lenovo, Huawei, or your hardware provider’s support for firmware updates, warranty service, or advanced diagnostics.
