Urgent support for Power HA System Mirror for IBM i of the new IBM Spectrum Virtualize function Policy-based HA (the new Hyperswap function)

With the last announcements of IBM storage, the IBM Spectrum Virtualize Software is enhanced with the new functions based on Policy-based HA (the new Hyperswap function).

The PowerHA system mirror for i, today doesn't support this new function and Storage brand announce that the current known Hyperswap will be removed starting with the next version of IBM Spectrum Virtualize Software (now the last version is 8.7). From a technical point of view the old Hyperswap presents itself to the IBM i hosts as a single cluster with a PowerHA LUN switching configuration. The new PB-HA is based on a concept of Logical HA partitions and it presents itself to the IBM i hosts as a dual node cluster. PowerHA LUN switiching is not able to support this configuration.

    The CAAC has reviewed this IBM Idea and recommends that IBM view this as a high priority Idea that is important to be addressed

    We feel that Hyper-swapping is of great value for the PowerHA tool kit.

    The CEAC has reviewed this requirement and recommends that IBM view this as a HIGH priority requirement that urgently needs to be adressed. Otherwise, PowerHA could not be used in this setup any more which would render the high availability setup of customers useless and could impact there environment dramatically.

CEAC has a crucial role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community and has therefore reviewed your RFE.
