28 Nov 17 An xpinfo that works in hpvm guests and on non Hitachi storage

Hitachi shops faced annoyance times two:
1. xpinfo does not work on non-Hitachi storage for example Pure storage
2. xpinfo does not work on hpvm guests depending on how the storage is passed through from the hpvm host

I now present xpinfonew which though raw and unfnished
The output:

myserv0:root > ./xpinfonew

Should work on any SAN based storage
