From dd5cc4086bda53c2cd1a845c472816719d1dd50c Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Fri, 19 Feb 2016 09:17:01 +0100 Subject: [PATCH] scsi_dh_alua: call alua_rtpg() if stpg fails If the call to SET TARGET PORT GROUPS fails we have no idea what state the array is left in, so we need to issue a call to REPORT TARGET PORT GROUPS in these cases.
