Subject: [PATCH 7/8] target_core_alua: disallow READ_CAPACITY when in standby
Date: Thu, 18 Jun 2015 11:43:41 +0200 [thread overview]
Message-ID: <1434620622-65391-8-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1434620622-65391-1-git-send-email-hare@suse.de>
Strictly speaking SPC doesn't require READ CAPACITY and friends
to be supported while in the port is in standby.
