Replacing/Repairing a failed drive in 2-node Hyper-V S2D Cluster.

Question

Hello! I'm working with a 2-node Windows Server 2022 Hyper-V S2D Cluster (we'll call the nodes HV1 and HV2). There are 8 x 4TB NVMe drives per server, and 2 CSVs (two-way mirror/CSVFS_ReFS) used for VM data storage.

HV1 had a physical disk lose connection and was subsequently auto-retired. The storage pool (fixed) and both CSVs are shown to be healthy and online.

I have a replacement drive on hand, but I'd like to also attemp to re-seat the existing failed/retired drive in case it was actually just a connection issue. How do I safely go about this, while also keeping the cluster up and running?

Hi Justin Buckley,

Thanks for your post. Please refer to the following steps to replace drivers:

1. Check status of storage subsystem and storage jobs by using PowerShell:

Get-StorageSubSystem Cluster | Get-StorageJob

2. See physical disk footprint:

Get-PhysicalDisk | ft DeviceId,FriendlyName,SerialNumber,Uniqueid,*Status,foot,Usage,PhysicalLocation

3. Retire bad disk, one specific disk

Get-PhysicalDisk -SerialNumber XXXXXXXXX | Set-PhysicalDisk -Usage Retired

4. See physical disk footprint (to get any disk by SerialNumber). Monitor until footprint is zero.

Get-PhysicalDisk -SerialNumber XXXXXXXXX | ft DeviceId,FriendlyName,SerialNumber,Uniqueid,*Status,foot,Usage,PhysicalLocation

5. Remove retired disk from storage pool.

$FailedDisk = Get-PhysicalDisk -SerialNumber XXXXXXXX

$Pool = $FailedDisk | Get-StoragePool -IsPrimordial:$false

Remove-PhysicalDisk -StoragePool $pool -PhysicalDisks $FailedDisk

6. Enable LED light of physical disk on a server rack, to more easily identify the disk.

Get-PhysicalDisk |? -SerialNumber XXXXXXXXX | Enable-PhysicalDiskIdentification

7. Physically remove the failed disk from the server chassis.
8. Physically install the new disk into the server chassis.
9. Disable LED light of physical disk on a server chassis.

Disable-PhysicalDiskIdentification

10. Add new physical disk into pool.

$disk = Get-PhysicalDisk |? CanPool -like True

Get-StoragePool S2D | Add-PhysicalDisk -PhysicalDisks $disk

11. Get virtual disk and repair virtual disk. Repair job may start on its own.

Get-VirtualDisk

Repair-VirtualDisk VirtualDiskName

12. Wait until repair completes.

Get-StorageJob

13. Once the repair storage jobs are complete, repeat steps above for any other capacity disks which need to be replaced.

Best Regards,

Ian Xue
