Bug Description

NetApp iSCSI drivers use discovery mode for multipathing, which means that we'll fail to attach a volume if the IP provided for the discovery is not accessible from the host.

Something similar would happen when using singlepath, as we are only trying to connect to one target/portal.

NetApp drivers should return all targets/portals available and not use discovery multipathing to avoid these issues.

    NetApp: Return all iSCSI targets-portals

    NetApp iSCSI drivers use discovery mode for multipathing, which means
    that we'll fail to attach a volume if the IP provided for the discovery
    is not accessible from the host.

    Something similar would happen when using singlepath, as we are only
    trying to connect to one target/portal.

    This patch changes NetApp drivers so the return target_iqns,
    target_portals, and target_luns parameters whenever there are more than
    one option.

    Changes to be committed:

    As part eseries driver code is still in the tree. Need to propose
    an additional patch to the stable branch, notice that patch
    would not be in master, even though both have the same issue.
