Export all active and standby Distributed Switch Portgroup uplink ports using PowerCLI

But almost as important as the reverse/forward DNS lookup is the correct time given by a local NTP service. I learned it the really hard way and will probably tell… Continue reading Check the time.

Just a quick reference to bookmark, may someone think it's useful. Spending time to rescan HBA's on all hosts in a cluster is time consuming and not worth the work. It is possible to rescan all HBA's with a simple PowerCLI line: Get-Cluster -Name “Clustername” | Get-VMHost | Get-VMHostStorage -RescanAllHba or if you have more… Continue reading Rescan all Hosts HBA’s | It’s that simple!
