From 3a95e8eb34f595a0144adb6e5513d456319bd8a5 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Fri, 1 Aug 2008 16:39:10 +0200 Subject: [S390] ipl: Reboot from alternate device does not work when booting from file During startup we check if diag308 works using diag 308 subcode 6, which stores the actual ipl information. This fails with rc = 0x102, if the system has been ipled from the HMC using load from CD or load from file. In the case of rc = 0x102 we have to assume that diag 308 is working, since it still can be used to ipl from an alternative device.
