From 441b7195e2812f2d7a9dafe02f052f642957bd8f Mon Sep 17 00:00:00 2001 From: Erwan Velu Date: Fri, 1 Mar 2019 17:08:06 +0100 Subject: scsi: smartpqi: Reporting 'logical unit failure' When the HARDWARE_ERROR/0x3e/0x1 case is triggered, the logical volume is offlined. When reading the kernel log, the reason why the device got offlined isn't reported to the user. This situation makes it difficult for admins to root cause. Log a message when this condition occurs.
