I recently migrated a few vSphere environments with external PSC’s to vSphere 7 and noticed some PSC leftovers afterwards. Now a lot is already written about the deprecation of the External Platform Services Controller (PSC) deployment model so I will not go into this. What I do want to highlight is the importance of the […]

Everyone knows the situation in where a (s)VMotion asks you to select a Resource Pool. I would love to see that VMware automatically selects the current VM’s Resource Pool but unfortunately we have to make a selection since it defaults to the cluster.

Automatic Rescan of your HBAs… How to enable this again
Duncan Epping wrote an helpful article about disabling the automatic rescan of HBA’s whenever you add, remove of expand a datastore. Remember, turning this off isn’t a best practise for production environments but could come in handy when building a new site while avoiding “rescan storms”. Now the trick is to enable […]
