Establishing trust between HPE OneView and remote devices
A session between an HTTPS or TLS client and an HTTPS server is considered secure only when the client and server can exchange the appropriate certificates. For example, if HPE OneView is communicating with the server iLO, HPE OneView is the client and iLO is the server. To ensure a secure connection, HPE OneView must have the appropriate iLO certificates (which can be the iLO self-signed certificate, or a CA-root certificate and any intermediate certificates used to sign the iLO certificate in a PKI environment) in the local trust store.
HPE OneView requires that the root and any intermediate certificates that form the full chain of the appliance CA-signed certificate are also imported into HPE OneView when the CA-signed appliance certificate is imported to the appliance.
