From 3859f6a248cbdfbe7b41663f3a2b51f48e30b281 Mon Sep 17 00:00:00 2001 From: Andreas Herrmann Date: Sat, 27 Aug 2005 11:07:54 -0700 Subject: [PATCH] zfcp: add rports to enable scsi_add_device to work again This patch fixes a severe problem with 2.6.13-rc7. Due to recent SCSI changes it is not possible to add any LUNs to the zfcp device driver anymore. With registration of remote ports this is fixed.
