From 5e47167b6be0ca24cbb04fb71ea611ab7c089aff Mon Sep 17 00:00:00 2001 From: Brian King <brking@linux.vnet.ibm.com> Date: Thu, 28 May 2009 16:17:32 -0500 Subject: [PATCH] [SCSI] ibmvfc: Improve device rediscovery For certain scenarios during device rediscovery, we detect we need to log back into a target. Currently we do just that - PLOGI/PRLI back into the target. Change the code to delete and add the target from the FC transport layer as well, to ensure we handle any cases where the target may have changed.
