We successfully installed Linux with one network card (OSA) on S/390. Now we want to install more network cards (OSA) in Linux. How is this done? Many thanks.

Are you wanting to run a multi-homed system (multiple cards on one machine)with each card offering specific services?

Yes, multiple adapter cards (OSAs), each with its own IPADDR. Users will access LINUX over the various IPADDRs. We have the one adapter (OSA) installed and configured via the install process. Now we want to add a couple more OSA adapters. What is the command sequence/procedure to do this? Thanks.

Check out the Net-HOWTO (can be found at http://www.linuxdoc.org/HOWTO/Net-HOWTO/index.html ).

In short, if your cards are PCI and fully supported, depending on your distribution, they may be just "plug-n-pray". Chapter 6.3 ( http://www.linuxdoc.org/HOWTO/Net-HOWTO/x1100.html ) has a description of assigning/verifying ethx names to the individual cards.

Then, to set up the IP addresses of the individual cards, check your ifcfg-eth? files (in redhat, they're in /etc/sysconfig/network-scripts/ ).

To manually bring up/down interfaces, /sbin/ifup eth?, /sbin/ifdown eth?. When you're all done, /sbin/ifconfig should verify all your interfaces are good.

Ditto. I'm sure if the poster could enlighten the populace here as to what distro we are using there may be more specific answers forthcoming. Otherwise it's straight to the glorious land of How-To's for you. I must admit though that I am more than a little envious of someone getting the run of the ranch on an S/390. Kinda makes my pile of Intels look like so many shiny trinkets.
