How to rebuild the RAID on a new, empty chassis using HDDs from a replaced or faulty DIP 74XX unit (gen 4)?

The RAID configuration is stored on the HDDs themselves, not only on the chassis.
So when you move all original disks together into a new, empty chassis, the system can import the existing RAID instead of creating a new one.

Step-by-step guide

1. Power off the new unit

• Make sure the new DIP 74XX chassis is completely powered off

• Do not insert disks while powered on

2. Insert the HDDs from the faulty unit

• Insert all HDDs from the faulty/replaced DIP 74XX unit

• Keep the original disk order (slot 1 → slot 1, slot 2 → slot 2, etc.)

  • This is critical to avoid RAID inconsistency

If the RAID is degraded after powering on the new unit, please refer to the following steps for the RAID import:

3. LSA RAID import steps

Drives marked as Unconfigured Bad must be set to Unconfigured Good before they can be imported for RAID rebuild.

1. Select drive make unconfigured Good:

2. Make sure the “unconfigured Good drive” is selected and click “Yes, Make Unconfigured Good” button:

3. Select Foreign Configuration for the “Unconfigure Good” drive:

4. Import the “Foreign Configuration”

5. Foreign Configuration drive successfully imported:

6. Rebuild RAID after the drive is imported

When the RAID is healthy but VHDs / LUNs are not visible, you can manually import (attach) the VHDs using PowerShell.

PowerShell procedure to import VHDs

1. Open PowerShell as Administrator

• Right-click Start

• Select Windows PowerShell (Admin)

2. List available VHD files & import VHDs

• Navigate to the folder where DIP stores VHDs: Get-ChildItem -Path "D:\\" -Recurse -Filter *.vhd*

• Attach (import) the VHD. Use the following command as example: Mount-VHD -Path "D:\VHDs\Recording_LUN1.vhdx"

  • This attaches the VHD without modifying data.

3. Verify the disk is online

After mounting, check disk status: Get-Disk

If the disk is Offline, bring it online (Optional, if required): Set-Disk -Number <DiskNumber> -IsOffline $false
