In solaris you have /etc/path_to_inst in this file u can configure for each physical device path what will be his name in the system.
That is how you can configure nics with your own number(nic1=qfe2 & nic2=bge0 etc).
And those physical path will never be changed.

There is any functionality like this file in Linux (redhat)?

Believe it or not "Solaris" != "correct".

That is to say that just because Solaris does things a certain way doesn't mean it is the correct way to do it. It is simply the way the people that wrote that OS chose to do it. I've worked on many UNIX and Linux variants and distros and ONLY Solaris does it that way.

So rather than ask "why doesn't Linux do it like Solaris" you might ask "why doesn't Solaris do it like Linux" or "why doesn't Solaris do it like HP-UX" or "why doesn't Solaris do it like AIX".

All such questions imply an unwillingness to learn the differences and embrace them. I've worked on Linux, SCO, AIX, HP-UX and Solaris not to mention bizarre variants like Astrix (NEC's UNIX) and Qnix. Most of them do certain things in ways that I prefer. In fact Solaris with all its Berkleyisms was my least favorite but that didn't stop me from working on it for several years when my jobs required it.

I will change my question , because I think your right.

There is any /etc/path_to_inst in Linux like Solaris have,
if not, how linux mapping the pci devices permanently and
define their names in the OS by the physical path?

jlightner, I don't think there's any "unwillingness to learn the differences and embrace them". He knows how to do it in Solaris, he described the functionality, and he is asking how to achieve a similar thing in Linux. I see no problem in that, and I think it's a legitimate question to ask. This is not about which OS does the things in the right way, it's about how to do a given thing on Linux. Nothing else. At least that's my understanding.

It's true that the title could have been better chosen though. But 99% of the posts have an inaccurate title.

shaybery, I have a limited experience with Solaris, and only as a user, so I don't know if this will be 100% the thing that you describe. But I think you need this:

http://www.reactivated.net/writing_udev_rules.html

The document is extensive enough and as long as your distro is running udev (99% do nowadays) everything should work as explained in the document. It has instructions for many things, amongst them, network interfaces that is what you said you need on your first post. However, if you feel you need some extra help just ask back and I will try to do my best (though I am not a master in the subject).

Regards.
