LSI MegaRAID SAS 9361 8i Driver

The LSI MegaRAID SAS 9361 8i driver allows Windows to communicate with this LSI Logic storage controller and access the RAID virtual drives it presents. Installing a compatible driver helps the operating system recognize controller-managed storage during setup and normal use. For Windows 11, 10, 8, or 7, check the individual download’s compatibility details before installing, as support can vary by driver release.

Key Features

• RAID storage access: Enables Windows to detect and use virtual drives configured on the MegaRAID controller, rather than accessing each member disk independently.
• SAS and SATA storage communication: Provides the operating-system interface for supported SAS and SATA drives connected through the controller.
• Storage I/O handling: Translates Windows read and write requests into operations the controller can process, supporting routine storage workloads.
• Controller status reporting: Supports communication of storage status and errors to Windows. Detailed array monitoring and configuration may require a separate compatible MegaRAID management utility.

How to Install

1. Confirm the hardware and Windows version. Verify that your controller is the LSI MegaRAID SAS 9361 8i. Check your Windows edition and system architecture, then choose a driver package that explicitly supports that combination.

1. Prepare for the update. Back up important data, especially if Windows starts from an array attached to this controller. Download and extract the driver package to a local folder. For a new Windows installation, copy the extracted files to an accessible USB drive.

1. Install the driver in Windows. If the package includes an installer, follow its instructions. Otherwise, open Device Manager, locate the controller under Storage controllers or its unrecognized device entry, select Update driver, and browse to the extracted driver folder.

1. Load the driver during Windows setup if needed. If the installer cannot see the intended RAID virtual drive, select Load driver and browse to the compatible files on your USB drive. The controller must already have a suitable virtual drive configured; loading a driver does not create an array.

1. Restart and verify detection. Restart if prompted, then check Device Manager for controller warnings and Disk Management for the expected storage volumes. Do not initialize or format an existing data volume simply because it appears unfamiliar or inaccessible.
