HP RAID monitoring

I need some handholding getting a custom monitor created to monitor an HP Proliant server's physical drives.

I've looked at the thread in http://forums.manageengine.com/forumHome.do?forumGroupId=49000000002007&forumTopicId=49000002637781 and have loaded the CPQIDA MIB. It's now time to select a limb on the tree, and I am at a loss. How do I translate the abbreviated names and which one do I select to monitor the drives?
