To do this on all ESXi nodes in a cluster and for all LUNs used as RDM, you could do
$clusterName = 'cluster'
Get-Cluster -Name $clusterName -PipelineVariable cluster |
Get-VM |
Get-HardDisk -DiskType "RawPhysical", "RawVirtual" -PipelineVariable rdm |
ForEach-Object -Process {
Get-VMHost -Location $cluster -PipelineVariable esx |
ForEach-Object -Process {
$esxcli = Get-EsxCli -VMHost $esx -V2
$naaid = $rdm.ScsiCanonicalName
$esxcli.storage.core.device.setconfig.Invoke(@{device = $naaid; perenniallyreserved = $true })
}
}
