ZLM 7 whitepaper

Sigh.

I keep getting other priorities. Sorry to anyone who is waiting.

I’ll post a mindmap of where I am soon – problem is that there are still a lot of questions that I need to get answered on this.

My main pain right now is getting SLES 9 support packs cleanly into ZLM7 – this is driven by a customer request. My other pain is some of the internal workings of ZLM and how to best document that.

Thanks for your continued patience.

ZENworks Server Management

Wow. There has been a flurry of activity with ZENworks Server Management in the last month or so.

Martin Irwin in WorldWide Support built a set of CPKs to deploy ZENworks 6.5 SP2 across your infrastructure; he is now working on delivering this with the standalone CPK engine (think of this as a small part of the ZENworks Server Management subscriber agent) to all customers. That is way cool.

Peter Lambrechtsen in New Zealand has almost finalised a CPK (hopefully soon with the standalone engine) that will let you deploy ZENworks 7 in your network.

All very cool – and showing real savings for customers deploying ZENworks in an enterprise.

Centralised deployment, across hundreds of servers – in hours. Now that’s value.

ZENworks 7 Linux Management

Did you know you can use the imaging in ZLM7 to image Linux and Windows?

Nice solution for a standalone imaging solution if you just want a nearly-smart(*) imaging story. It’s fast, furious and does what I need.

(*) for true smartness use ZENworks 7 with the full policy enablement of imaging.

ZENworks 7 imaging

ZENworks OS imaging has always been based on the Linux kernel – it’s fast, efficient, has a great networking stack and is also extensible. None of the problems of DOS and getting NDIS drivers etc.

Earlier versions of ZENworks – (ZfD 3.x, ZfD 4.0, ZENworks 6, ZENworks 6.5) – spawned a slew of sites dedicated to tweaking this Linux environment. Notable is the Novell Forge Project zfdimgdrv. The imaging environment has also been extended by the likes of ENGL.

ZENworks 7 changed to a SLES 9 SP2-based kernel; this provides extensive hardware support (and real support; things that have been tested).

For unsupported hardware – or to add updated drivers – life is now a lot simpler.

Matt Misbach – one of the ZENworks engineers – passed on this tip:

  1. Obtain the binary driver file, it has the extension of “.ko”, (If no binary driver is available, then the source needs to be obtained and built on a sles9 sp2 machine.)
  2. On your ZENworks server mount the /srv/tftp/boot/initrd file using a similar command:
    mount -o loop /srv/tftp/boot/initrd /mnt
  3. copy the new .ko file into the /mnt/lib/modules/2.6.5-override-default/initrd
  4. umount /mnt

ZENworks 7 Linux Management – more

As mentioned I’m working on a best practices guide for ZLM7.

I’m writing a discussion of the package universe concept; how it differs from previous versions of ZLM (ZLM 6.x and RCE) and some design recommendations.

I also wrote a nifty script to populate the package universe 🙂 I’ll share that when I’ve tested it to death – but here’s the output:

Right now I can build all of my package universe as well as SP2 updates for SLES 9 and NLD 9. It takes about 20 minutes and minimal prep work.
