The Device Discovery Layer (DDL) allows dynamic addition of disk arrays. DDL discovers disks and their attributes that are required for SF operations.
The DDL is administered using the vxddladm utility to perform the following tasks:
List the hierarchy of all the devices discovered by DDL including iSCSI devices.
List the targets configured from a Host Bus Adapter
See Listing the targets configured from a Host Bus Adapter or a port .
List the devices configured from a Host Bus Adapter
See Listing the devices configured from a Host Bus Adapter and target .
