VMAX3 Cinder Driver support for SRDF/Metro

Hi,

I have a customer who wants to use IBM PowerVC to automate provisioning of PowerVM LPARs in a SRDF/Metro environment where the PowerHA cluster is stretched across 2 sites (within synchronous distance).  The latest IBM PowerVC release 1.3.2 is actually running Openstack Otaca under the hood, but the VMAX Cinder driver for Otaca shows support for only SRDF/S:

https://docs.openstack.org/ocata/config-reference/block-storage/drivers/emc-vmax-driver.html?cm_mc_uid=69602604219815028813412&cm_mc_sid_50200000=1504029021

Are there plans for the VMAX Cinder driver to support SRDF/Metro?

Any workaround possible if customer wish to use PowerVC (Openstack) to provision storage for the LPARs in an active-active environment (across 2 sites)?

Also, anyone knows if PowerVC 1.3.2 even support PowerHA stretched cluster (also called PowerHA geographically dispersed cluster)?

regards,

Sam
