Accessibility of datastore

[Mobster]

I need to determine whether a given datastore is accessible from ESX

hosts. I notice that the datastore MO has a property called

accessible. However, in my testing, even when I take the datastore down

(it was a test NFS datastore and I just shut the NFS host down), the

accessible property still return true.

Does anyone know of a way to determine when/if a given datastore is no longer accessible by an ESX host?

Many thanks in advance for your help.

Did you call UpdsateViewData after you powered off the NFS server ?

$ds = Get-Datastore <name> | Get-View
....
# NFS server powered off
$ds.UpdateViewData()
....

Note that in PowerCLI 4.1 you have access to the MO via the ExtensionData property.

Thanks LucD, calling UpdateViewData() refreshed the view and gets me correct information. However, now one more question nags at me. If I connect to the VC, then do a Get-Datastore etc and then check the accessible attribute, how do I know what _host that ds.accessible applies to? What is the given datastore is shared between 4 hosts, but for whatever reason is has become inaccessible on 2 - what would the accessible attribute mean then for the datastore?

Thanks again btw.

As it happens there is a script that does just that in my LUN report – datastore, RDM and node visibility post.
