Subject: [PATCH 1/8] scsi: hisi_sas: make SAS address of SATA disks unique
Date: Sat, 24 Mar 2018 00:05:08 +0800 [thread overview]
Message-ID: <1521821115-120040-2-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1521821115-120040-1-git-send-email-john.garry@huawei.com>
From: Xiang Chen <chenxiang66@hisilicon.com>
When directly connected with SATA disks in different SAS cores,
fill SAS address with scsi_host's id to make it's fake SAS address
unique.
