Subject: [PATCH 1/2] Drivers: scsi: storvsc: In responce to a scan event, scan the host
Date: Sat, 16 Aug 2014 20:09:47 -0700	[thread overview]
Message-ID: <1408244988-27456-1-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1408244954-27417-1-git-send-email-kys@microsoft.com>

The virtual HBA that storvsc implements can support multiple channels and
targets. So, scan the host when the host notifies that a scan is needed.
