The following features were introduced with the PowerMaxOS 5978 Q2 2019 Service Release (SR) and Solutions Enabler/Unisphere for PowerMax 9.1:
With Unisphere for PowerMax and Solutions Enabler 9.1 forward, we expanded our ODE support to include devices taking part in SRDF/Metro (Active) sessions; this new functionality is based on modifications to our existing Geometry Compatibility Mode (GCM) functionality for host visibility of devices.
Unisphere 9.1 also provides new ease-of-use functionality by automating the addition of devices to a storage group which then adds corresponding SRDF paired devices for single hop, concurrent, and cascaded SRDF configurations.
