LSI MegaRAID SAS 9261 8i Driver

The LSI MegaRAID SAS 9261 8i driver allows Windows to communicate with the LSI Logic storage controller and access the RAID virtual disks configured on it. Installing the appropriate driver helps the operating system recognize controller-managed storage and handle disk operations correctly. For Windows 11, 10, 8, or 7, check that the selected package explicitly supports your Windows version and system architecture before downloading.

Key Features

• Storage controller recognition: Provides the interface Windows needs to identify the LSI MegaRAID SAS 9261 8i and communicate with attached storage through the controller.
• RAID volume access: Enables Windows to read and write data on supported virtual disks created in the controller’s RAID configuration utility.
• SAS and SATA storage communication: Supports operating-system access to compatible SAS and SATA drives managed by the controller.
• Controller status reporting: Allows Windows to receive storage status and error information, helping with troubleshooting alongside compatible RAID management software.

How to Install

1. Confirm the hardware and Windows version. Open Device Manager to identify the controller, which may appear under Storage controllers or as an unrecognized device if no driver is installed. Verify your Windows edition and architecture, then review the driver package’s compatibility notes.

1. Download and extract the matching package. Save the LSI Logic driver to a local folder and extract it if necessary. Back up important data before changing storage drivers, especially when the controller hosts your Windows boot volume.

1. Run the installer or update manually. If the package includes a setup program, run it as an administrator. Otherwise, right-click the controller in Device Manager, select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder.

1. Load the driver during Windows setup if needed. If you are installing Windows and the configured RAID volume is missing from the disk selection screen, place the extracted driver files on a USB drive. Choose Load driver and select the matching controller driver. A virtual disk must already be configured for Windows to use it.

1. Restart and verify operation. After installation, restart if prompted. Check Device Manager for warnings and confirm that the expected volumes appear in Disk Management. Do not initialize or format an existing data volume merely because it is not immediately accessible.
