From 999b3ffc0f3b12bb9eeafabaa88176bb7acb84a1 Mon Sep 17 00:00:00 2001 From: Raghava Aditya Renukunta Date: Thu, 2 Feb 2017 15:53:32 -0800 Subject: scsi: aacraid: VPD 83 type3 support This patch adds support to retrieve the unique identifier data (VPD page 83 type3) for Logical drives created on SmartIOC 2000 products. In addition added a sysfs device structure to expose the id information. Signed-off-by: Raghava Aditya Renukunta Signed-off-by: Dave Carroll Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
