Hi Christophe, Hannes, Martin, Xose and Benjamin, It is beneficial for our customers if we integrate a new path group prioritizer into the multipath-tools. But this prioritizer is vendor-specific and it only works for Huawei storage system. Will the community accept such new vendor specific path group prioritizer in libmultipath/prioritizers? I know that the multipath-tools accepted some vendor specific prioritizer such as emc.c , hp_sw.c, ontap.c and so on in the libmultipath/prioritizer in 2008~2010 and there were no newer vendor specific prioritizer. Before I get down to writing a new Huawei prioritizer, I want to hear your thoughts. If it is convenient for some of you , please let me know your ideas. Thanks. Best wishes.
