Cluster Expansion is another significant value add which helps prepare the cluster nodes before adding them to the HCI cluster. OMIMSWAC readies the cluster nodes before adding them, but expanding a cluster requires some steps recommended by Microsoft. For details about creating and expanding clusters, see HCI Operations Guide—Managing and Monitoring the Solution Infrastructure Life Cycle. The new node to be added is checked for high-level compatibility, licensing, and HCI Configuration Profile to ensure it can be added successfully and consistently. Following these checks, a compliance check will be performed to ensure the new nodes’ BIOS, firmware, and driver versions are consistent with those running on the cluster. If in case the new node is non-compliant the workflow will guide through an update process where the node is updated followed by a reboot.
