Subject: [PATCH 5/8] tcm_loop: Rescan SCSI target on transport online
Date: Thu, 18 Jun 2015 11:43:39 +0200	[thread overview]
Message-ID: <1434620622-65391-6-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1434620622-65391-1-git-send-email-hare@suse.de>

Setting the transport status to 'online' needs to rescan the
target, as some devices might have been added while the transport
has been offline.
