A datastore is more likely to be selected if there are hosts in the cluster with free reserved DRS slots connected to the datastore. When you do full cluster-wide maintenance (all hosts simultaneously) the vCLS VMs will be deleted, and new VMs will be created indeed, which means the counter will go up“Compute policies let you set DRS’s behavior for vCLS VMs” Note also that the vCLS virtual machines are no longer named with parenthesis, they now include the UUID instead. 0 U3 it is now possible to configure the following for vCLS VMs: Preferred Datastores for vCLS VMs; Anti-Affinity for vCLS VMs with specific other VMs; I created a quick demo for those who prefer to watch videos to learn these things if you don’t skip to the text below. 0 Update 1, DRS depends on the availability of vCLS VMs. config. enable/disable cluster. clusters.
