From ea460a81919f2b3410e7fb30183c0256d068d87a Mon Sep 17 00:00:00 2001 From: Swen Schillig Date: Fri, 15 May 2009 13:18:20 +0200 Subject: [SCSI] zfcp: Changed D_ID left port disabled If the destination ID (D_ID) of a remote storage port changed, e.g. re-plugged cable on the switch in a different switch port, the port was never (re-)attached within Linux. This patch fixes the broken mapping between the WWPN and the D_ID.
