However, what seems strange is that these VMs have been recreated a whole bunch of times, as indicated by the numbers in the VM names: vCLS (19), vCLS (20), vCLS (21), vCLS (22), vCLS (23), vCLS (24), vCLS (25), vCLS (26), vCLS (27) I've noticed this behavior once before: I was attempting to. I have no idea why. When selecting the vCenter Server instance in the vSphere Client and you go to Monitor > Skyline Health, it'll list all the vCLS enabled clusters. 2. In this blog, we demonstrate how to troubleshoot and correct this state automatically with vCenter's "Retreat Mode. This might occur, for example, if no host can satisfy the virtual machine's CPU or memory resource needs or if no host currently has network or storage access needed by the virtual machine. ago. When you add the first three hosts to the cluster, vSphere Cluster Services (vCLS) agent virtual machines are added by default to the cluster. This option was added in vSphere 7 update 3, together with the option to create also Anti-Affinity for vCLS VMs not running with specific VMs. Look for 'Retreat Mode'. cfg.
