Mappare i dischi non NVMe dischi sull'istanza Amazon EC2 Windows ai volumi

PowerShell Lo script seguente elenca ogni disco con il nome e il volume del dispositivo corrispondenti.

Connect all'istanza di Windows ed esegui il comando seguente per abilitare l'esecuzione PowerShell dello script.

Set-ExecutionPolicy RemoteSigned

Copiare lo script seguente e salvarlo come mapping.ps1 nell'istanza Windows.
