Description of problem:
Installed AS2.1 on IBM Netfinity 350. When install reboots and external raid is
reconnected the system doesn't boot properly;  it comes up and complains that it
can't find init, presumably because the driver for the qlogic FC card that runs
the array is somehow confusing the driver for the internal ips card. Thus the
installation is unable to read the internal disks.

Version-Release number of selected component (if applicable):
kernel 2.4.9-e.3smp,  Red Hat Linux Advanced Server release 2.1AS/\m (Pensacola)

How reproducible:
Always

Steps to Reproduce:
1. Install
2. Reboot
3. Unable to see internal disks
    


Expected Results:  normal install with full disks available.

Additional info:

It boots fine as long as the external raid isn't attached. Once the raid is
attached then the issue appears.

Unfortunately, there's no way on x86 hardware to determine what is actually the
boot controller.  With 2.1, if you boot with 'linux noprobe', you can load the
SCSI drivers in the order that they should be and the drives will then be in the
correct order (or do your install with your FC array disabled).

RHEL3 has a somewhat more elegant solution to this (allowing you to pick the
drive ordering in an advanced boot loader options screen)

I don't think you understand the problem here.  We do have 2.1AS installed on
the internal RAID with the ips driver.  The problem is when the external FC
array is attached the system won't boot.  We've run into this problem before on
older versions of your product (6.2, 7.3) but have always been able to work
around it by  editing /etc/modules.conf to change the order the modules load in.
 On this system, the qlogic FC driver gets loaded first, even if the only
scsi_hostadapter alias in /etc/modules.conf is for the ips driver.

During the install, we actually had to remove the external raid entirely. 
'linux noprobe' didn't help, as it had in the past; after prompting for a driver
disk, the installer automatically loaded drivers for the qlogic, adaptec, and
ips controllers in the system, in that order, which is basically exactly backwards.

While I find it hard to conceive of a situation where someone wouldn't want the
internal raid to show up first, I can almost understand the current default. 
What I can't understand is why there seems to no longer be any working way to
modify that default.

It has been over a week since the last update on this.  Do you have a timeframe
in which we can expect resolution, or at least a workaround?

Comment 5 Arjan van de Ven 2003-10-08 16:19:34 UTC
It appears you request support and SLA like resolution; you really should work
via our support people for that, that way they can track things properly.
