HDev A Dev (partition) in an LU that the host recognizes via the
HDLM driver. It is called a host device. One host device is
recognized for one Dev in the storage system.
HLU An LU that the host recognizes via the HDLM driver. It is

one host LU is recognized for each LU in the storage system.
Program Configuration
HDLM is actually a combination of several programs. Because each program
corresponds to a specific HDLM operation, it is important to understand the
name and purpose of each program, along with how they are all interrelated.
Figure 2-4 Configuration of the HDLM Programs on page 2-9 shows the
configuration of the HDLM programs.
