Re: Get-Content PowerCLI to apply IOPS settings on all LUNs

You could read the WWN into an array and then use the Contains operator to check if the current device belongs to your list of targets.

Something like this

$wwn=Get-Content-PathC:\WWN.txt
$esxHosts=Get-VMHost-Location$mycluster|SortName
foreach($esxin$esxHosts)
{    $esxcli=Get-EsxCli-VMHost$esx
    $esxcli.storage.nmp.device.list() |where {$wwn-contains$_.Device}|%{        $esxcli.storage.nmp.psp.roundrobin.deviceconfig.set($null,$_.Device,1,"iops",$null)      }
}
