Keeping up with the changes

[Moray Henderson (ICT)]

Oh, it's not hardware vendor you would need to detect: it's the individual hardware Model!  You should be able to get that sort of stuff with  dmidecode though.


http://linux.dell.com/files/whitepapers/consistent_network_device_naming_in_linux.pdf lists the models and also tells you how to turn it off, which will be helpful in the short term.



Is there a Thing like list-harddrives available yet to help kickstarters work out what their network card is called - or which is the Ethernet and which the Wireless?  Or any tips for people wanting to do it the New Way?

Is this applicable for all HW vendors with RHEL 6u2 or just Dell? If you work with a variety of vendors like I do..thats a concern. I don't want to try to deal with determining the vendor during the kickstart.

Thanks!

I believe this is mentioned at least by:

- Dell in their release notes for each platform
- Dell PowerEdge blogs, Meaningful names for network devices in RHEL 6.1 on Dell systems ...<http://www.google.com/url?sa=t&rct=j&q=site:dell.com+redhat+em1&source=web&cd=1&ved=0CCIQFjAA&url=http://en.community.dell.com/techcenter/b/techcenter/archive/2011/05/26/meaningful-names-for-network-devices-in-rhel-6-sp1-on-dell-systems.aspx&ei=MsQmT_vzBeWL4gT21sz6DA&usg=AFQjCNGST4KB4s2ar2GSzlSTA_5_coEGzQ>
- Dell OS And Application notes, http://en.community.dell.com/techcenter/os-applications/w/wiki/red-hat.aspx
- Dell whitepapers, http://linux.dell.com/files/whitepapers/consistent_network_device_naming_in_linux.pdf
- RedHat in their technical notes for RHEL 6u1 and 6u2 (pages 7, 189)

etc.

>From my POV there wasn't much to change and now the name of the interface (em1) corresponds to interface labeled Gb1 on the back of the server.

You did not mention which rhel version you are using but interfaces on dells in rhel 6.1 will show up as em1, em2, etc. by default instead of eth0, eth1. Both dell and redhat mention it in their docs.

Pretty soon I'm going to have to start updating the software I develop and maintain for RHEL 6.  Apparently, I'm going to have to rewrite the entire set of perfectly-working network code because many (but not all) of my customers use Dells.  What's the best place to keep up with changes like this - to learn not just what they are, but the reasons for them and the lists of exactly what hardware combinations produce which responses in the OS?
