A little post from me since I got an error message while working with large RDM’s. While I twittered out the message it seemed that Duncan Epping from VMware had a posting ready at which he only had to press the “Publish”-button. See his very helpful article over here. What you might have noticed is that a RDM’s size is displayed as the real size […]

You should get info like this: Host VMotionning to (receiving) Nov 7 21:13:14 xxxxxxxx vmkernel: 10:06:06:18.104 cpu3:9131)VMotionRecv: 226: 1257624621919023 […]

VMware Update Manager on vSphere – Check the Firewall!
Yesterday I noticed something strange while updating a VI3 environment to vSphere with Update Manager 4.0 The update of update manager went fine as well as the creation of new baselines. Whenever I remediated a Host, the Host went into maintenance mode and the remediate process hangs on 33%. This same behaviour occured when I […]

The Quest of Encrypted VMotion
Last week I was dreaming (don’t even ask…. 😉 about the new VMotion encryption technology that VMware has implemented in vSphere. Since that moment I decided that I want to know more about this feature since there isn’t much said about it at the moment. Let’s go back before vSphere: Ever since VMotion exists […]
