raghavendrat 577e2ee108 HPE 3par: Unable to create clone of replicated vol

Two possibilities of clone volume:
1] same size, online copy

Existing behaviour: start clone & return from function.
Error occur because clone is not yet complete and
code tries to create vol on secondary array.

2] size is different, offline copy

Existing behaviour: (i) create new replicated vol.
(ii) during clone operation below error occur:
Volume is involved in remote copy
(iii) Since clone operation fails, delete new replicated vol (as cleanup).

To overcome both possibilities, code changes are done.

For clone of replicated vol, create offline copy only.
Steps:
(i) Create new vol without replication.
(ii) Perform clone operation; wait till completion (offline copy).
(iii) Create vol on secondary array.
