From 97f604b07473669f4da52b1f859ee45e8d48d42a Mon Sep 17 00:00:00 2001 From: Stefan Weinhuber Date: Fri, 11 Sep 2009 10:28:28 +0200 Subject: [PATCH] [S390] dasd: fail requests when device state is less then ready A DASD device that is not ready or online has no defined disk layout, so all requests that arrive in such a state need to be returned as failed.
