The cinder.volume.drivers.emc.emc_smis_common Module

Common class for SMI-S based EMC volume drivers.

This common class is for EMC volume drivers based on SMI-S. It supports VNX and VMAX arrays.

class EMCSMISCommon(prtcl, configuration=None)

Common code that can be used by ISCSI and FC drivers.
