B. Differences Between HDLM Version 5.9 or Later and Version 5.8.1

or Earlier

HDLM version 5.9 or later supports MPIO used by AIX 5L V5.2 or later, which has

improved compatibility with the OS. The items explained in the following subsections

represent the changes from HDLM version 5.8.1 or earlier.

B.1 Add-in HDLM Driver Module

HDLM version 5.9 or later supports MPIO used by AIX 5L V5.2 or later. This has

improved compatibility with the OS because users can use standard OS commands to

manage paths on HDLM management-target devices. As compared to HDLM version

5.8.1 or earlier, HDLM version 5.9 or later differs in terms of the HDLM driver

structure, environment configuration, and HDLM operation procedures.
