Unable to Detect HDD when Using SAS Interface on an Intel® Server Board

The hard disk cannot be detected when I used Serial Attached SCSI (SAS) on the Intel® Server Board. However, the same HDD can be detected by the Advanced Host Controller Interface (AHCI).

The troubleshooting steps to resolve this issue depend on whether the operating system (OS) is installed on the Intel® Server Board.

If the OS is installed on the Intel Server Board:

1. Download the corresponding Intel® Rapid Storage Technology enterprise (Intel® RSTe) AHCI and SCU Software RAID Driver for Windows*.
   1. To do so, go to the Download Center and search your Intel Server Board model.
   2. In the search result, look for Intel® Rapid Storage Technology enterprise (Intel® RSTe) AHCI and SCU Software RAID Driver for Windows.
2. Unzip the downloaded driver.
3. Open the unzipped folder and look for the F6-drivers folder.
4. Unzip the zip file in the F6-drivers folder.
5. Open the Device Manager > right-click the SAS controller > click Update driver > click Browse my computer for driver software > click Browse to select the path of the F6-drivers folder > check Include subfolders > click Next.
   • Refer to Open Device Manager on how to open Device Manager. 
6. Open Disk Management. You will see the new hard disk is offline. Right-click the disk and select Online.
   • To open Disk Management, right-click the Start button and select Disk Management.

If the OS is not installed on the Intel Server Board:

1. Download the corresponding Intel® Rapid Storage Technology enterprise (Intel® RSTe) AHCI and SCU Software RAID Driver for Windows.
   1. To do so, go to the Download Center and search your server board model.
   2. In the search result, look for Intel® Rapid Storage Technology enterprise (Intel® RSTe) AHCI and SCU Software RAID Driver for Windows.
2. Unzip the downloaded driver.
3. Open the unzipped folder and look for the F6-drivers folder.
4. Unzip the zip file in the F6-drivers folder.
5. Copy the extracted folder to a USB flash drive and select the corresponding folder when installing the operating system.

   Note	Consult your OS manufacturer to confirm the specific driver import method.
