From 5c12f2406cea24a2c885a8d3e5aa7ab94c65f0d5 Mon Sep 17 00:00:00 2001 From: Stefan Weinhuber Date: Wed, 5 Mar 2008 12:37:10 +0100 Subject: [PATCH] [S390] dasd: let dasd erp matching recognize alias recovery When a request fails that was started on an alias device then the first recovery step is to retry it on the base device. If the recovery request fails again with the same symptoms, the next step should not be a simple retry, but should be a proper recovery based on sense data, etc. To do so, the dasd recovery functions need to recognize the alias recovery step in the erp chain by comparing the start devices.
