IDPA: DP4400 no boot device found

Applies to:

• DP4400

Symptoms:

• System fails to boot and displays error:
  "No boot device found" or "Boot device unavailable"
  • Error observed using system console (Serial, KVM, or iDRAC)
• No fault LEDs illuminated on the chassis or visible disks
  • Note: The BOSS card itself does not have fault LEDs

• BOSS card is not fully inserted into PCIe slot (Slot 3 on PCI Riser 1)
• M.2 drives are not properly seated on the BOSS card (gold fingers may be visible)
• BIOS boot order is incorrect - the AHCI Controller is not set as the primary boot device

The BOSS card contains two 240GB M.2 drives in a RAID 1 configuration and hosts the operating system and boot partition. Improper installation or configuration prevents the system from locating the boot device.

1. Power Down the System

• Shut down the DP4400 appliance
• Disconnect AC power cables

2. Inspect and Reseat Hardware.

• Locate PCI Riser 1 and verify that the BOSS card is fully inserted into Slot 3
• Check both M.2 drives on the BOSS card:
  • Ensure that they are properly seated
  • No gold fingers should be visible — this indicates a misaligned or loose connection

3. Verify BIOS Boot Settings.

• Access the system BIOS
• Confirm that the AHCI Controller is selected as the Primary Boot Device

4. Power On and Test

• Reconnect AC power and power on the system
• Monitor boot process using console (Serial, KVM, or iDRAC)

5. Escalation

• If the issue persists after reseating and BIOS verification, contact your support provider and raise a Service Request

Example:
No gold fingers should be visible when the Drive is correctly inserted.
The image below shows a correctly installed Drive in slot 1.
Slot 0 has 'gold fingers' showing and is NOT fully seated.
