Those are all dynamic commands.  If you want to keep that configuration across 
an IPL, you'll need to create the proper configuration files.  See the 
discussion from last week on VLAN tagging and channel bonding.

VLAN disappear at reboot

2011-04-05 Thread Victor Echavarry Diaz 
I'm configure a VLAN. Everything goes fine when I IPL the Linux guest the VLAN 
configuration disappear. How I solve it? This is on SLES 10SP2

This is the steps I'm doing

vconfig add eth1 922

ifconfig eth1.922  192.168.92.166 netmask 255.255.255.240 up

Webcast: April 6/7 Problem Reporting and Analysis Linux on System z - How to survive a Linux critical situation

2011-04-05 Thread Pamela Christina April SNOW-ers today 
Cross-posted to IBMVM, IBMMAIN, and Linux390 for those who enjoy
the no charge webcasts about System z topics

Choice of two live calls or you can wait for the replay in a few days.

Abstract:
You encounter a problem with Linux on System z and you don't know what to
do. This webcast will introduce you to a trouble shooting "First Aid Kit"
for Linux on System z. This kit is something you will always want to have
on hand - just in case. Our speaker, Sven Schuetz, will guide you through
examples of real customer problems, their diagnosis, and solutions. Maybe
yours is among them.


Direct your questions about this lvc to jul...@us.ibm.com

Re: cross compiling for s390

2011-04-05 Thread Harold Grovesteen 

Adam, if you run into any problems, I monitor both this and the
crosstool-NG list. I contributed the s390 samples to crosstool-NG.

There is a next gen release of this package out, called crosstool-NG.

It has a Mercurial repository available at

It is much nicer and requires much less knowledge to operate than the old
crosstool.

The tiny geeky part in me could enjoy using a full z196 to cross
compile for an ARM phone :-)  It is very elegant that the toolchain
actually supports such a process.

When I did my cross compiles back in 1999, the hand-me-down laptop
outperformed the G4 CPU by enough that I could afford to share over
NFS and do unzipping and compiles on the latop :-)  That clearly shows
the expectation problems we had with Linux performance on the early
mainframe CPUs. The balance now is the other way: my current laptop
may be 2 times as fast, but the modern mainframe CPU gained a factor
20 since then. I envy my friends with a z196.
