PS1, Line 10: version details of ISHC.
> The query was about an older description. The description has since been updated to reflect the changes in implementation. The current implementation of the API retrieves partition information, and it is not specific to ISHC. In subsequent changes, the API will be used to retrieve ISHC version.
>
> I understand your suggestion to include the purpose of ISHC retrieval in the description. I will include that information in the pertinent subsequent changelist.

@Dinesh, please add the details in the commit msg itself.
