Trying to find Number active paths per Lun

[jedijeff]

I am trying to find the number of active paths to just a single Lun, for monitoring whether I had a fiber connection go down. I keep getting boxed in a corner, because at first just using a Get-view of a host and fish around in the multipathsection. But really I want to simply test 1 Lun on all my hosts to see how many active paths each host has to it. And it appears any of the Get-ScsiXX commands you cannot specify a single lun.

Am I getting confused somewhere?

Did you try it like this

$canonicalname = "naa.600507540180809ef0000000000001ba" 
$esx = Get-VMHost -Name MyEsx

Get-ScsiLun -VMHost $esx -CanonicalName $canonicalname | 
Select CanonicalName,
  @{N="Active Paths";E={Get-ScsiLunPath -ScsiLun $_ | where {$_.State -eq "active"} |  Measure-Object | Select -ExpandProperty Count}}

aha! Yes I bet that will work. I was trying to figure out how to do this with naa ID. Let me try this first thing in the morning, I will post back.
