Connectivity type detection for a data storage system in accordance with the present description includes, in one aspect of the present description, automated host-target discovery logic which is configured to automatically discover the connectivity type for a connection path between a host and a storage system, and select and initiate target discovery procedures which are appropriate for the discovered connectivity type. As a result, mapping a target volume of the target storage system which is connected to the host, may be facilitated, reducing or eliminating delays which may have otherwise resulted from the change in connectivity type. In this manner, efficiency of the computing system may be improved. Other aspects and advantages may be realized, depending upon the particular application.
