From 1f1148c88ad37c87f14d2153416a605bf0aeaf74 Mon Sep 17 00:00:00 2001 From: Peter Oberparleiter Date: Fri, 11 Sep 2009 10:28:14 +0200 Subject: [PATCH] [S390] cio: fix ineffective verify event Path verification events occurring for offline devices are currently ignored. As a result, offline devices are not removed, even though they might no longer be accessible (for example because the last path to the device was varied offline). Fix this by scheduling a status evaluation for the affected subchannel when a path verification event occurs.
