PowerVC to map initiators with DS8884 HA ports across I/O enclosures to achieve high availability & load balancing

Current Situation:
Customer is using PowerVC 1.3.2 to enable cloud based infrastructure. Customer is using Power8 E880 servers & DS8884 storage system which is integrated with PowerVC. While deploying new VM, PowerVC maps each initiator with a single HA port (target) . PowerVC picks HA ports (target) from same I/O enclosure & same slot. This does not provide high availability by mapping HA ports (target) across I/O enclosure and also load balancing of HA ports across many VMs is not achieved

Propose Solution:
To have a white-list of WWPNs (HA ports) which will enable the customer to map specific HA ports & we understand that this is being planned in the next release of PowerVC.

A provision to define & control on a deploy by deploy basis of the HA ports with multiple white-list of WWPNs

To have a provision as "Advanced" configuration option for an administrator to select specific white-list from PowerVC GUI while deploying new VMs

    This is supported now in PowerVC 1.4.4 release, with configuring initiator port groups feature. Thanks again for this suggestion!
