Explanation
Hitachi ODM (D) must be installed first because AIX uses its Object Data Manager database to recognize and configure hardware devices. Hitachi provides custom ODM definitions that teach AIX how to identify Hitachi storage devices - without these entries, AIX cannot see the storage, making HDLM installation impossible or non-functional.
Why the distractors are wrong:
- A (MPXIO) is a Sun/Oracle Solaris multipath solution, not an AIX technology - it has no role in an AIX environment.
- B (HACMP) is IBM's AIX clustering software; while HDLM can integrate with it, it is not a prerequisite for HDLM installation.
- C (HTnM agent) belongs to Hitachi Tuning Manager, a separate performance monitoring product - it is independent of HDLM installation.
Memory tip: Think of Hitachi ODM as the "dictionary" AIX must read before it can "speak Hitachi." No dictionary = AIX can't recognize the storage = HDLM has nothing to manage.
