SLES 11 HAE guide

Since last month I’m studying a nice topic like the “High Availability” on Linux OS. If you have a SLES 11 and a license for High Availability Extension add-on, this guide could be really helpful for a good understanding. The lack of official and well documented procedures it’s really common for these graceless topics, but this one with its 495 pages looks awesome.


It’s a really comprehensive manual accompanied with simple examples and many pictures & screenshots. If you want to get familiar with words like Corosync, OpenAIS, STONITH and other, please give it a try. In case you have previous versions like the HA Extension SP1, most of commands seem to work perfectly. From the release notes of SP2 you can see that big changes to components haven’t been done, and that’s what care most 😉 (especially for enterprises environments)

Thanks SuSE for the great job, that’s why I like this distro for Enterprise purpose! Here the link to the page for the .pdf file.
