From 31e060774cf5c3b9945f6f16d6c18d6eae18e4d9 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Fri, 20 Oct 2017 10:05:51 +0100 Subject: migration: Add 'pre-switchover' and 'device' statuses Add two statuses for use when the 'pause-before-switchover' capability is enabled. 'pre-switchover' is the state that we wait in for management to allow us to continue. 'device' is the state we enter while serialising the devices after management gives us the OK.
