From faff6ee05379ad1e27c6a77706f107734a00705e Mon Sep 17 00:00:00 2001 From: "Stephen M. Cameron" Date: Tue, 18 Feb 2014 13:57:42 -0600 Subject: [SCSI] hpsa: only do device rescan for certain events Do no rescan on every events -- way too many rescans are triggered if we don't filter the events. Limit rescans to be triggered by the following set of events: * controller state change * enclosure hot plug * physical drive state change * logical drive state change * redundant controller state change * accelerated io enabled/disabled * accelerated io configuration change Signed-off-by: Stephen M.
