The problem related to migrating some Exchange mailbox servers from a legacy ESXi 4.1 host onto new ESXi 5.1 host. This should have been a simple vMotion operation, but the task … Continue reading “vMotion operation fails with the error, “The VM failed to resume on the destination during early power on”.”

We recently experienced a number of recurring, unexpected restarts of guest VM’s, all Windows 2008 R2 servers running MSSQL Server 2008. These VM’s were all hosted on ESXi 5.0.0 build-1489271 (update 3). All hosts in the cluster are relatively new HP DL380p Gen 8 servers, with two Intel Xeon E5-2667 v2 processors @3.3GHz. My first … Continue reading “Intel microcode issue affecting E5-2600 v2 series processors”

We recently upgraded our NTP infrastructure and I had to reconfigure 46x ESXi 5.0 hosts to reflect this change. I’m not keen on doing these types of operations manually so I wrote this script to automate the process. I’m sure there are definitely more elegant scripts available, but this one works perfectly well. Just change … Continue reading “Update NTP configuration on multiple ESXi 5.0 hosts”
