You can use the vSphere Automation API to initiate the remediation of a cluster or a standalone host through the vSphere Lifecycle Manager.
To remediate a cluster with a desired state, call the apply_Task(cluster_ID, apply_spec) method of the com.vmware.esx.settings.clusters.Software interface. Pass as argument a SoftwareTypes.ApplySpec instance and specify whether the VMware End User License Agreement (EULA) must be accepted. You can also set the minimum commit ID of the draft software specification that must be used for remediating the cluster. Upon successful completion of the remediation task, all hosts in the cluster have the same software state.
To remediate a standalone host with a desired state, call apply_Task(host_ID, apply_spec) method of the com.vmware.esx.settings.hosts.Software interface and pass as arguments the standalone host ID and an instance of the SoftwareTypes.ApplySpec class. Use the software apply specification to set the minimum commit identifier of the draft software specification. See Committing the Draft Software Specification. You can also specify whether the VMware End User License Agreement (EULA) must be accepted.
