AW: LVM Help
please do man vgcfgrestore
I always had success restoring the vg configuration. this should help.
Please take a look at /etc/lvmconf/
you should run vgcfgbackup from time to time and then you will find old vg
configurations.
then you can restore lvm vg information with:
Example: restore vg information for volume group vgDATA
MYVG=vgDATA
pvscan|grep $MYVG|awk -F'' '{ print $2 }'|while read MYDEVICE
do
vgcfgrestore -f /etc/lvmconf/${MYVG}.conf.1.old -n $MYVG $MYDEVICE
done
also copy this older configurations to another server or use a backup tool
to keep this files save.

Betreff: LVM Help
Yesterday I was trying to expand an existing LVM filesystem and it
appeared ok after I issued the resize2fs command but after I rebooted
the Linux instance the filesystem was mounted but it was not the correct
file system. It appears LVM got the expanded file system confused with
another file system. In trying to correct this problem I think I
corrupted another file system. When I issue a vgdisplay command I get
the following:
vgdisplay -- ERROR: VGDA in kernel and lvmtab are NOT consistent;
please run vgscan
I ran vgscan but it didn't help. I found what appeared to be backups
of volume group information in /etc/lvmconf directory. Is there a way
to recover the LVM to a previous state or recover the volume group info?
We are SLES 7 with the 2.4.7 kernel.
AW: server consolidation
For my opinion no one can realy give you a cost comparison nor say TCO will be better in on or another way. Ok: IBM, HP, SUN and so on will do this. But I never saw that this master plans fits into reality ! They're looking good on high gloss paper. Not more. See, this depends on too many individual things like: - structure of the company - what's the goal of the company ? - IT-skill of the people - open-minded people (no one ever had spcified what you pay dumb,blinded people) - how many servers you have to consolidate ? - how is the structure of the servers ? - is there a company-wide standard for application, server-installation, development ? (no standards - no consolitation) - how is your managment minded ? - how do you handle support and problem-managment ? Many companies offer now software for Linux. BUT intel-Linux :) We had so many requests to companies for Linux-Products but most of the things you really need to be productive you're not getting now. Things like linuxcare and other managment software you get for linux. But your not making money with managment-tools and middle-ware. Also you need strong matured software for enterprise environments. Well, for me it's not possible to give you a detailed answer. Sorry ! But if one out there, please let me know !

Dezember 2003 16:09 An: [EMAIL PROTECTED] Betreff: server consolidation I am curious to know who out there has been able to use Linux/390 to actually replace production based servers (Windows or Unix)? What types of servers have been replaced or are being targeted for replacement (file, web, e-mail, print, etc.)? And finally, can anyone point me to a cost comparison (TCO?) document online or make one available? Thanks.
SYSLOGD for z/VM and SSH
Hi there ! Does anyone knows if there is a SYSLOGD for z/VM available ? Also tools to generate syslog-messages via REXX then ? Further on I am looking for SSH under z/VM.

AW: DB2 query tool for zLinux???
normally you need to install DB2 Connect for z/Linux. Or perhaps you can use perl with the db-module. Therefore you need to build the the DB-module and this requires only the db2 libraries. hmthis could workbut I am not sure. regards, Martin -Ursprüngliche Nachricht- Von: Roger Boussen/audax [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 7.

AW: Perpetuating Myths about the zSeries
well, CPU-Performance is not everything. Its always a question about the whole system (and application behavior). If you need pure CPU-Power then IBM z/Series would be the wrong choice. But most of the systems don't have permanent a cpu high load. If you need availability and scalability (on-demand freatures), then you more on the right path with the z/Series. But Linux needs for that dynamic reconfiguration tools ! (like dynamic memory,cpu attach and detach) On the other hand, my experience is that many of the projects take a look on the coast side (with a very partial focus) and nothing else...and that's the fault of the sales people. They sell systems and later on a very clever guy is coming with the consolidation idear. But in the meanwhile every little server is so special in his application behavior and SLA's that nobody takes the coast of the consolidation. Hypothetical consolidation is a big word, practical it's a lot of work and also cost intensiv then. Clever people may think about a long term strategy and then z/Series would be more cost-effective. -Ursprüngliche Nachricht- Von: Post, Mark K [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 30. Oktober 2003 22:49 An: [EMAIL PROTECTED] Betreff: Re: Perpetuating Myths about the zSeries My answer was, and still is (and likely always will be) avoid any application that is CPU intensive. Yes, the zSeries has gotten faster, but so has Intel. The price-performance curve for CPU intensive work still favors Intel. I've seen nothing in the IBM announcements that would lead me to change any of the recommendations I've been making for the last 3 years. Unless and until the price-performance curve for zSeries matches that of Intel (or comes a couple of orders of magnitude closer), I will continue to make the same recommendations.

It started getting pushed on the zSeries 3 years ago and the software and hardware have made great strides in the last 3 years. So CGI may not be appropriate today. So what is there we said was not appropriate 2 or 3 years ago that may be appropriate today on Linux zSeries? = Jim Sibley Implementor of Linux on zSeries in the beautiful Silicon Valley Computer are useless.They can only give answers.
