Problems in installing RedhatLinux on Z900

[ramki]

When I try to IPL Redhat Linux 7.2 on a Z/OS LPAR it does not pick up the
network device that it is supposed to pick up , therefore Iam unable
to connect to the LPAR thru telnet . Can anybody Help ?

hello,
i will assume you have the redhat build that is meant for the z900 - it is kinda hard for me to find specs on this machine, esp. the networking part. is there any option for adding a network interface when you run redhat-config-network (something like that...) or netconfig?

I tried tweaking my Linux box to change some network config
stuff but it does'nt give any results
When I install Linux on Zseries and when it comes to configuring the network interface it says it cannot find any
device
Or rather when I type "ifconfig eth0" at command prompt
it gives me a message:
Error finding interface information
Device not found

Please help

here try this :

type dmesg | less (the bar there is the pipe, in case you didnt know, or wasnt clear. My pipe is near my backspace key.)

Then scroll on down. You should see where there is a bunch of parts being identified and a driver being attatched. Keep going until you discover

a) No NIC being seen.
b) A NIC is found, and it happens to use XXYYZZ driver.

This will clue us into the next step. Obviously if there is no NIC being detected, that sucks, and may want to try antoher one. Possibly another brand. I have been using the $20 linksys cards for some time now with great reliability.

if you see a detected NIC, you can run setup from the command line as root.
