This document (7018393) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12 Service Pack 2 (SLES 12 SP2)

Situation

After a new installation of SLES12 SP2, kdump is failing to load the crash kernel.
systemctl status kdump shows the following errors.
 kdump.service - Load kdump kernel on startup
 Loaded: loaded (/usr/lib/systemd/system/kdump.service; enabled; vendor preset: disabled)
 Active: failed (Result: exit-code) since Wed 2016-11-09 20:14:32 JST; 4min 56s ago

Resolution

Please open a service request (SR) and request a PTF for this problem.
As a temporary workaround you can edit the file /etc/default/grub and change the line:

GRUB_CMDLINE_LINUX_XEN="crashkernel=XXX"
to
GRUB_CMDLINE_XEN_DEFAULT="crashkernel=XXX"

where XXX is a placeholder for the size of the crash kernel.

After saving this file you need to run grub2-mkconfig(8)


Cause

This is a known bug and will be fixed in the next maintenance update of rubygem-cfa_grub2.
