Subject: [PATCHv8 04/23] scsi_dh_alua: call alua_rtpg() if stpg fails
Date: Fri, 19 Feb 2016 09:17:01 +0100	[thread overview]
Message-ID: <1455869840-122786-5-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1455869840-122786-1-git-send-email-hare@suse.de>

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.
