Description of problem:
I want to install RHEL4U1 on a dual-core dual Opteron Blade from IBM (BladeCenter LS20).
According to IBM, only local installs are possible:
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=ibm&lndocid=MIGR-60579
Our blades don't have local disks, but connect to a HP EVA3000 SAN and boot from that.
According to information I have found on the net, to enable MPIO, one has to boot with "linux noprobe" and specify the qla2300-module with the "ql2xfailover=1" option - this works for RHEL3U5-i386, but when I do that with RHEL4U1, the keyboard isn't recognized anymore and I can't continue the installation.
This is because the BladeCenter uses an USB-keyboard (infact, everything that isn't SCSI is USB)

Is there a way to only not load the qla2300-module but all the rest?


Version-Release number of selected component (if applicable):
RHEL4U1-x86-64

How reproducible:
Always

Steps to Reproduce:
1. boot with linux=noprobe
2. watch as your keypresses are ignored
3. bang your head against blade-chassis
4. repeat..
  

Actual Results:  Nothing

Expected Results:  Keyboard detected

'noprobe' does exactly what it sounds like and doesn't probe for _anything_ now.
 You probably want one of the more granular probing things such as "nostorage"

Comment 2 Rainer Duffner 2005-10-03 18:22:27 UTC
Well, I was looking for a list of options, but I couldn't find one.
In fact, I can't even find information about this command when I explicitly feed
google with it, except for mailinglist entries.

Additionally: does RHEL4U1 actually support the qla2xfailover=1 option or do I
have to compile my own kernel?
