VMware driver not discovering iscsi targets while attaching cinder volumes

[Sabari Murugesan]

VMware drivers cannot dynamically add iscsi targets presented to it while attaching a cinder volume. As a result, the instance cannot be attached to a cinder volume and fails with a message 'unable to find iscsi targets'.

This is because the driver fails to scan the Host Bus Adapter with the iscsi target portal (or target host). We need to fix the driver to scan the HBA by specifying the target portal.

    VMware: iscsi target discovery fails while attaching volumes

    VMware Drivers are unable to discover iscsi targets because
    the api calls fail to specify the iscsi server location
    (referred in the code as target portal) to retrieve targets.
    This is critical for the attach_volume feature to work with
    iscsi supported cinder drivers.
