features:
  - Support for VMAX SRDF/Metro on VMAX cinder driver.
VMAX driver - Implement SRDF Metro feature SRDF/Metro allows a remotely replicated (SRDF) secondary device to be read/write accessible to the host, taking on the external identity of the primary device (geometry, device WWN, and so on). Both the primary and secondary devices may then appear as a single virtual device across the two SRDF paired arrays. With both devices being accessible, the host can read and write to both primary and secondary devices, with SRDF/Metro ensuring each copy remains current and consistent, addressing any write conflicts which may occur. This patch adds this functionality to the VMAX cinder driver.
