Finding VM with Fixed or Round Robin MultiPath Policy

Objective: In some cases, we need to change the Path Selection from RoundRobin to Fixed or vice versa, It is quite difficult to check each VM and change their RDM path policy.

Solution: A Simple script using VMware PowerCLI can get the list of VMs that are using Fixed or RoundRobin Selection Path.

1-Find all VMs with Fixed Selection Path

Get-VM | Get-HardDisk | Where-Object {$_.DiskType -like “Raw*”} | Where-Object {$_.MultipathPolicy -notlike “RoundRobin”} | Select @{N=”VMName”;E={$_.Parent}},Name

2-Find all VMs with RoundRobin Selection Path

Get-VM | Get-HardDisk | Where-Object {$_.DiskType -like “Raw*”} | Where-Object {$_.MultipathPolicy -notlike “Fixed”} | Select @{N=”VMName”;E={$_.Parent}},Name

You can export list to CSV format bu using

| Export-Csv C:\RDM-list.csv -NoTypeInformation

Output:
