HPE3PARISCSIDriver Initialization Failure (for Alletra Storage MP) #104
Description
We're trying to integrate Alletra Storage MP (10.4.5) against RHOSP 13.0.9 (Queens) as a second storage backend. Despite having tried multiple versions of <python-3parclient-4.2.x> packages from PyPi site (e.g., 4.2.11, 4.2.12, 4.2.14), we keep getting the following <cinder-volume.log> errors. We do realize Alletra MP is certified against RHOSP 16 and above, but we're looking for a way to make it work against RHOSP 13 since an OSP release upgrade at this time is not feasible. Any ideas? Many thanks in advance.
