vSphere Datastore Last Updated timestamp – Take 2

I referenced this in an earlier post, but we continue to have datastore alarm problems on hosts running 4.0U2 connected to a 4.1 vCenter. In some cases, the timestamp on the datastore does not update, so it’s not just the alarm having a problem but also the datastore timestamp. As a stopgap measure, we scheduled a little PowerCLI script to automatically run to ensure all of the datastores are refreshed. We then accelerated our upgrade plans to quickly eliminate the problem from our primary datacenter. We now only have it in our DR site, so it’s not critical anymore, just annoying.

if ( (Get-PSSnapin -Name VMware.VimAutomation.Core -ErrorAction SilentlyContinue) -eq $null )
    Add-PsSnapin VMware.VimAutomation.Core
Connect-VIServer yourserver.foo.com
$ds = Get-Datastore
foreach ( $dst in $ds )
   $dsv = $dst | Get-View
   Write-Host "Refreshing "$dsv.Name

    Unfortunately, I don’t know. The issue resolved itself when we upgraded the hosts from 4.0U2 to 4.1 and I haven’t seen anything like this since. I never saw an official KB article about it or anything, the claim about it being a known bug came from VMware support.
