Is the example below, you’ll see a power-off and a delete operation. The algorithm tries to place vCLS VMs in a shared datastore if possible before. Each cluster will hold its own vCLS, so no need to migrate the same on different cluster. Or if you shut it down manually and put the host into Maintenance Mode, it won't power back on. In vSphere 7. Configuring Graphics. Admins can also define compute policies to specify how the vSphere Distributed Resource Scheduler (DRS) should place vCLS agent virtual machines (vCLS VMs) and other groups of workload VMs. Improved interoperability between vCenter Server and ESXi versions: Starting with vSphere 7. The datastore for vCLS VMs is automatically selected based on ranking all the datastores connected to the hosts inside the cluster.

When the nodes are added to the cluster, the cluster will deploy a couple of vCLS virtual machines. As listed in the documentation, there will be 1 to 3 vCLS VMs running on each vSphere cluster depending on the size of the cluster. The lifecycle for vCLS agent VMs is maintained by the vSphere ESX Agent Manager (EAM). ” Since all hosts in the cluster had HA issues, none of the vCLS VMs could power on. The vCLS monitoring service initiates the clean-up of vCLS VMs. When a vSAN Cluster is shutdown (proper or improper), an API call is made to EAM to disable the vCLS Agency on the cluster. 0 U1 VMware introduced a new service called vSphere Cluster Services (vCLS).
