Hi Todd,

Few things:
    * Please provide path group id from 'pgindex' of struct path.

    * Replace key name 'host adapter' with 'host_adapter'.

    * Remove output properties as many as you can, only expose
      those with clear user case and good definition.
      For API, it's easy to add but hard to remove or change.
      For example: IMHO, we don't need to expose
      hcil, next_check, size, serial right now,

    * Performance concern. I am getting bad performance(25 seconds
      while previous 'raw format' way only take 1.5 seconds) on 10k
      disks. I am still investigating which part slow things down.

Thank you.
Best regards.
