The cinder.volume.drivers.hpe.hpe_3par_fc Module

Volume driver for HPE 3PAR Storage array. This driver requires 3.1.3 firmware on the 3PAR array, using the 4.x version of the hpe3parclient.

You will need to install the python hpe3parclient. sudo pip install –upgrade “hpe3parclient>=4.0”

Set the following in the cinder.conf file to enable the 3PAR Fibre Channel Driver along with the required flags:

volume_driver=cinder.volume.drivers.hpe.hpe_3par_fc.HPE3PARFCDriver

class HPE3PARFCDriver(*args, **kwargs)

Bases: cinder.volume.driver.ManageableVD, cinder.volume.driver.ManageableSnapshotsVD, cinder.volume.driver.MigrateVD, cinder.volume.driver.BaseVD

OpenStack Fibre Channel driver to enable 3PAR storage array.
