I am trying to find additional information on how Netapp single_image mode works in a clustered environment as it pertains to pathing. Single_image mode pulls all the WWPN's from the Netapp cluster and presents it to the SAN as one WWNN. What I would like to know is how paths are determined from hosts to cluster nodes if no target portals are defined?
There will be multiple paths available (at least 2, one for ClusterA, one for ClusterB) and you generally will need host-based path selection software to select the active one.
Some software selects on 'Most Recently Used', other selects on fixed path, this may vary per multipathing-software.
