system.

recognizes via the HDLM driver. It is called a host device.
No matter how many physical paths exist, one host
device is recognized for one Dev in the storage system.
Program Configuration

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.
The following figure shows the configuration of the HDLM programs.
