From 4d0695664ed8e168f97cce86289d0c5fab35b067 Mon Sep 17 00:00:00 2001 From: "Kashyap, Desai" Date: Thu, 17 Jun 2010 14:37:25 +0530 Subject: [PATCH] [SCSI] mptfusion: Use DID_TRANSPORT_DISRUPTED instead of DID_BUS_BUSY Changed the return value for Nexus Loss IOs to be DID_TRANSPORT_DISRUPTED. What this will allow is the multi-path driver to delay the fail over process. They would like the path to keep up as long as the nexus loss Loginfo is return from firmware. With DID_BUS_BUSY the path fails over immediately.
