Collecting a support bundle from all the nodes in a vCenter HA cluster helps with troubleshooting.

When you collect a support bundle from the Active node in a vCenter HA cluster, the system proceeds as follows.
  • Collects support bundle information from the Active node itself.
  • Collects support bundles from Passive and Witness nodes and places them in the commands directory on the Active node support bundle.
Note: The collection of support bundles from the Passive and Witness nodes is a best effort and happens if the nodes are reachable.
