must be installed ahead of time on the host. The cable port on the storage
system is called a port (P) on a channel adapter (CHA) used for iSCSI
connections.
A logical unit (LU), which lies in a storage system, is either an input target or
an output target to or from a host. The areas within an LU are called Devs.
A route that connects a host to a Dev in an LU is called a path.
HDLM assigns a unique ID to each management-target path. This ID is called
AutoPATH_ID. Sometimes, the path is also just simply called a management
target.
