RAID Card Detection Validation Procedure

RAID Card Detection Validation Procedure

This document outlines the standard technical steps to validate whether a RAID controller card is installed and detected correctly in a server system. These steps should be followed by field engineers and support teams whenever RAID detection issues are reported.

Physical Layer Validation

  1. RAID card is installed in the correct PCIe slot as per SOP.
  2. The RAID card is firmly seated and properly secured.
  3. All SAS/SATA cables are connected correctly between the RAID card and backplane.
  4. Correct cable model and routing are used as per vendor guidelines.
  5. Power indicators on the RAID card (if available) are ON.

Verification in System BIOS

Steps to confirm RAID card detection in system BIOS:

  1. Reboot the server.
  2. Press DEL or F2 to enter BIOS setup.
  3. Navigate to: Advanced → PCIe / PCI Configuration.
  4. Verify that the RAID controller is listed as a detected PCIe device.
  5. Confirm that the device name matches the installed RAID card model.

Expected Result: The RAID controller should appear as a detected PCIe device. If it is not listed, the card is not detected at the hardware level and further troubleshooting is required.

RAID Controller BIOS Validation

Most RAID controllers include their own BIOS utility which loads during system POST.

  1. Reboot the server and observe RAID controller initialization messages.
  2. Look for prompts such as CTRL+R, CTRL+C, or CTRL+H to enter RAID BIOS.
  3. Enter the RAID configuration utility.
  4. Verify RAID card model, firmware version, and connected physical drives.
  5. Check whether logical volumes are created and visible.

Expected Result: RAID BIOS should load successfully and display connected disks. Failure to access this utility indicates detection or firmware issues.

Operating System Level Validation

Windows Validation:

  1. Log into Windows operating system.
  2. Open Device Manager.
  3. Navigate to Storage Controllers.
  4. Confirm that the RAID controller is listed without errors.
  5. Install and open RAID management software (e.g., MegaRAID Storage Manager) to verify health status.

Linux Validation:

  1. Run the command: lspci | grep -i raid
  2. Verify RAID controller appears in the output.
  3. Check disk visibility using: lsblk
  4. Use RAID utilities such as storcli or megacli to confirm array status.

Information to Attach in Support Tickets

For proper documentation, the following evidence should be included in any support ticket:

  1. BIOS screenshot showing RAID controller detection.
  2. RAID BIOS configuration screenshot.
  3. Operating system device manager or command output.
  4. Logs from RAID management utilities.
  5. Photos confirming physical installation and cabling.

Troubleshooting if RAID Card is Not Detected

  1. Reseat the RAID card and verify slot placement.
  2. Test the card in another PCIe slot.
  3. Cross-test the card in a different server if possible.
  4. Replace SAS/SATA cables and retest.
  5. Update server BIOS and RAID card firmware.
  6. If issue persists, initiate RMA for the RAID controller.
