Default Behavior

LSI_SAS3i is a kernel device driver. In Windows 10 it is starting only if the user, an application or another service starts it. If LSI_SAS3i fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the LSI_SAS3i service has failed to start due to the error.

1. Select your Windows 10 edition and release, and then click Download.

2. Save the Win10_LSISAS3i_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

The LSI_SAS3i service is using the lsi_sas3i.sys file that is located in the %WinDir%\System32\drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
