Unable to Create Cluster Volumes

[Eric Hansen]

There are issues when using is_multiattach for volumes and attempting to attach them to multiple LPARs in a PowerVC environment.

There needs to be a way to bypass this exception, since IBM PowerVC systems are not providing a way to attach volumes to additional nodes in an AIX cluster, the status of the volume is always going to be 'in-use' after being attached to the first cluster node. I don't see a way to make them 'available' to build clusters. I can even power off the system with the attached disks and that does not change the volume status.

https://opendev.org/openstack/openstacksdk/src/branch/master/openstack/cloud/_block_storage.py#L379

        if volume['status'] != 'available':
            raise exceptions.SDKException(
                "Volume %s is not available. Status is '%s'"
                % (volume['id'], volume['status'])
            )

A way to bypass the exception is requested.
