Dell OpenManage clarified

I have been struggling with Dell's OpenManage Server Management a bit lately. Mainly because other people asked me to try it and gave me wrong links to information. So I'll clarify it here, for those getting started as well, and hope it helps someone.

Dell Server Management has a lot (!) of components and you don't really need all (or any) of them. But they can be helpful. We'll use it for Server Management, mainly to monitor our PowerEdge 2950 servers but also (hopefully) to unify BIOS settings and DRAC configurations remotely. That's why we need OpenManage Server Administration (OMSA).

OMSA consists of a number of things:
- OMSA Server
- OMSA Managed Node
- OMSA ITA (IT Assistance)

You'll only need one server (maybe two for fail-over and redundancy). The easiest way to install the server is add a yum/up2date repo from Dell. but I had trouble finding the "OMSA agent" or "OMSA client" that I'd install on all servers to be monitored by the OMSA server. That's what you'll need the "Managed Node" software for. It's 80 MB and just finished downloading, so more later...

Preventing PuTTY timeouts

Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.

Dell Linux - OMSA Hardware Monitoring

Just getting started using Dell's OpenManage Server Administrator (OMSA) on our Oracle Linux platform. There are some confusing instructions going around so it's not immediately clear what to do, hence my blogging here. :) There is a site on Dell - Hardware Monitoring , as well as a wiki with instruction on how to setup their OMSA tooling using yum or up2date. [update]My first update for their instructions: be sure your server has Internet access, as most servers will use a proxy or so. use export http_proxy=http://yourproxy.example.com:port to configure it just for the session, and setup up2date to use an HTTP proxy by editing the settings in /etc/sysconfig/rhn/up2date .
