get-scsilun call performance

[kwvalenti]

I'm trying to determine how many devices are attached to each host in my environment.  When I call (get-scsilun -vmhost XXX).count on a 4.1 host, it takes around 4 seconds to complete.  When I make the same call against a 5.1 host, it takes around 74 seconds.  What can I do to improve my 5.1 host calls?

Thanks!

Yes, the Get-ScsiLun cmdlet tends to be a bit slow.

An alternative is to use the Get-EsxCli cmdlet.

Something like this

$esxcli = Get-EsxCli -VMHost MyEsx 
$esxcli.storage.core.device.list() | Measure-Object | Select -expandproperty count

That should give the same result, but a lot faster
