After you install the Multipath I/O (MPIO) feature on a server that's running Windows Server 2019 build 17763, you notice that the MPIO option is not available under Disk Management > Microsoft Storage Space Device Properties as it was in earlier versions of Windows.
To work around this issue, use a PowerShell cmdlet to configure MPIO. For example:
- Run Get-MSDSMGlobalDefaultLoadBalancePolicy in PowerShell to retrieve the MPIO policy.
- Run Set-MSDSMGlobalDefaultLoadBalancePolicy -Policy RR to set up the MPIO policy as round robin.
For more information, see MPIO.
