Hello
When LCM takes down a node prior to performing an update, AOS uses the Acropolis dynamic server (ADS) to migrate virtual machines to other nodes in the cluster. If you have VM affinity rules configured on your cluster, particularly affinity rules that restrict which nodes the VM can migrate to, then LCM can run slowly while waiting for ADS to migrate the VMs.
To avoid update failures or delays due to affinity rules, disable any VM affinity rules before beginning an LCM update and reenable the rules after performing the update.
