Topic: kdump on System z
Speakers: Michael Holzheu, Linux Kernal Developer, IBM Boeblingen
Abstract: The Linux kernel code is robust, but even the best kernel hackers
are only human and make mistakes. So, while kernel crashes are rare, they
can occur and are unpleasant events. To find the cause of such crashes,
kernel dumps containing the crashed system state are often the only
available approach. Because mainframes traditionally run mission critical
workloads, there is a particular big focus on the serviceability of the
platform. Customers expect that all problems are solved in a short time.
Therefore, when Linux was ported to s390 beginning of 2000, IBM also
provided a reliable kernel dump mechanism. This was about five years before
kdump was integrated into the upstream Linux kernel. In some areas kdump
offers advantages over the traditional s390 dump methods. Therefore, in
2011, kdump was ported to s390. The code was enriched by specific s390
features and, as much as possible, kdump was integrated into the existing
s390 dump infrastructure. This presentation reviews the traditional s390
Linux kernel dump methods describes the specifics of the s390 kdump port,
and explains the integration into the existing s390 dump infrastructure.

Hello,
You might find these links useful.
https://www.suse.com/support/kb/doc.php?id=7003414

Note the doc you linked refers to 3.2 kernel, not the 3.0.x kernel with
SLES11SP2
If you find the 1.1.5 version too old or has bugs which prevent it being
usable,
we can try requesting a maintenance update if needed.
HTH,

Hello list,
A customer is moving from SLES 10 SP4 to SLES 11 SP2. Can kdump be used
on these to capture dumps? I'm assuming SLES 10 SP4 is too old (?)
On http://www.ibm.com/developerworks/linux/linux390/kernel-3.2.html I
read: "Using kdump also requires s390-tools 1.17 and kexec-tools with s390
kdump support."
On a vanilla SLES 11 SP2 system, I see:
# cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (s390x)
VERSION = 11
PATCHLEVEL = 2
# rpm -qa | grep s390-tools
s390-tools-1.15.0-0.101.1
I also see a kexec-tools 2.0.0 RPM is available to install.
So it seems vanilla SLES 11 SP2 system would not have the necessary level
of s390-tools. So is there a 1.17 version of the RPM available for SLES
11 SP2? Thanks.
