  • Page 26: Discovering Targets By Using The Portal Address

    Configuring iSCSI Discovering targets by using the portal address During the initial stage of an iSCSI session, the appliance (initiator) sends a login request to the storage system to begin an iSCSI session. The storage system will then either permit or deny the login request, or determine that a login is not required. If authentication is enabled on the target, the credentials must be authenticated and the session established before the server can access the storage resources.
