If are talking about disablement though I think it should not be done at the iscsi layer. It should be some sort of white/black list at the scsi device layer or something like that. However, I will ping Microsoft and cc you and we can see what is up for sure. Maybe we will get lucky and they will have a release with a fix on their side. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
