List MPIO disks active paths

This is a single liner PowerShell for listing active paths on MPIO disk devices:

(gwmi -Namespace root\wmi -Class mpio_disk_info).driveinfo | % {Write-host "Name: $($_.name) Paths: $($_.numberpaths)"}

Tested on Windows Server 2012 R2. This single liner should also work on other Windows Server editions.

And in case if there are multiple servers for checking the active paths on MPIO disk devices, here is the modified single liner (it's presumed that user running the bellow single liner owns the necessary permissions, and there are necessary firewall rules for accessing remote servers):

"server1","server2","server3" | % { write-host $_ -ForegroundColor green  ; (gwmi -ComputerName $_ -Namespace root\wmi -Class mpio_disk_info).driveinfo | % {Write-host "Name: $($_.name) Paths: $($_.numberpaths)"}}

Tested also on Windows Server 2016.
