Getting RAID Status from Windows Host to Hyper-V: Seeking Guidance We configured RAID on a Windows Server using a MegaRAID® controller.

Hi, As far as I know the storcli tool can only get information of the raid controllers on the local machine. To run storcli on the VM, try passing through the raid controller to the Hyper-V VM using DDA. However, you will no longer be able to access the raid controller and the raid volumes from the Hyper-V host. https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/deploying-graphics-devices-using-dda Or you can run storcli remotely from the VM if your VM is connected to a Hyper-V internal or public switch so it can communicate to the Hyper-V host. The storcli tool can be invoked using the PowerShell cmdlet Invoke-Command like below. Invoke-Command -ComputerName "HyperVHostname" -ScriptBlock {C:\file\path\storcli.exe /c0 show all} https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/invoke-command?view=powershell-5.1 You may need to run Enable-PSRemoting on both Hyper-V VM and host to configure the computers to receive remote commands before using Invoke-Command. https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/enable-psremoting?view=powershell-5.1 Another option is other raid tools that can connect to remote computer like the MegaRAID Storage Manager. You can confirm this with Broadcom. Best Regards, Ian Xue If the Answer is helpful, please click " Accept Answer " and upvote it.

You may need to run Enable-PSRemoting on both Hyper-V VM and host to configure the computers to receive remote commands before using Invoke-Command.

@Ian Xue

Thanks for replying and your help.

Based on your suggestions and further research, here is my understanding of getting RAID status from the Windows Host to Hyper-V:

Approach 1: Passing through the RAID controller to the Hyper-V VM using DDA

Direct access to the RAID controller from the VM.

We will no longer be able to access the RAID controller and the RAID volumes from the Hyper-V host (Windows Host).

**
Approach 2: Running StorCLI remotely from the VM**

The StorCLI tool can be invoked using the PowerShell cmdlet Invoke-Command.

Since our VM is Debian-based, executing PowerShell commands from it is tricky.

Due to these limitations, we do not prefer this approach 1 and 2.

Possible Solutions:

1. SSH with PowerShell Remoting

Use SSH to log into the Windows Server and run the PowerShell command.

ssh user@windows-server_ip 'powershell -Command "storcli.exe /c0 /vall show"'

- Prerequisites:

Set up OpenSSH Server on Windows Server.

Configure SSH Access with ssh-copy-id.

Configure Windows Firewall for SSH access.

2. Creating a Simple Web Service on the Windows Server:

I have created a web service with Python Flask on the Windows Server to execute StorCLI commands and access it from the Debian VM.

Example Python Script for Web Service (Running on Windows Server)

from flask import Flask, jsonify import subprocess app = Flask(__name__) @app.route('/raidstatus') def raid_status(): result = subprocess.run(["C:\\Path\\To\\storcli.exe", "/c0", "/vall", "show"], capture_output=True, text=True) return jsonify(result.stdout) if __name__ == "__main__": app.run(host="0.0.0.0", port=5000)

Access from VM:

Use the following command to get the complete RAID monitoring status:

root@DEB-HYPV-38d22exxxxx:~# curl http://<windows-server-ip>:5000/raidstatus

The status will be returned in a JSON file. I can use this JSON file in my Debian based VM for further operations.

- Prerequisites:

Install Python, Pip, and Flask on the Windows Server.

Run the web service script on the Windows Server.

I need assistance with the following:

How can I get the Windows Host Name or IP in my Debian-based Hyper-V VM?

Are there any better tools than StorCLI to manage the MegaRAID controller that would fulfill my requirements more easily?

Thanks in advance, and your suggestions and help will be appreciated.

Best regards,

Samadhan.

How can I get the Windows Host Name or IP in my Debian-based Hyper-V VM?

I successfully retrieved the Hyper-V VM Host Name from a Debian-based Hyper-V VM.

Since Debian 12 does not hv_kvp_daemon preinstalled, I installed it along with the hyperv package to read the necessary files:

root@DEB-HYPV-Debian12:~# apt-get install hyperv-daemons root@DEB-HYPV-Debian12:~# pip install hyperkv

Finally, I ran hyperkv and obtained the following output:

{ "HostName": "WIN-SRGVS7XXXXX", "HostingSystemEditionId": "79", "HostingSystemNestedLevel": "0", "HostingSystemOsMajor": "10", "HostingSystemOsMinor": "0", "HostingSystemProcessorArchitecture": "9", "HostingSystemProcessorIdleStateMax": "0", "HostingSystemProcessorThrottleMax": "100", "HostingSystemProcessorThrottleMin": "5", "HostingSystemSpMajor": "0", "HostingSystemSpMinor": "0", "PhysicalHostName": "WIN-SRGVS7XXXXX", "PhysicalHostNameFullyQualified": "WIN-SRGVS7XXXXX", "VirtualMachineDynamicMemoryBalancingEnabled": "0", "VirtualMachineId": "18A2EE6D-B528-4103-A1BF-8B21C9FE324F", "VirtualMachineName": "Debian12_VM" }
