[Linux-cluster] RHEL Problem: Can't access LUNS

[Filipe Miranda]

Mike,

I got this from the URL:
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/ref-guide/ch-modules.html

"During installation, Red Hat Enterprise Linux uses a limited subset of
device drivers to create a stable installation environment. Although the
installation program supports installation on many different types of
hardware, some drivers (including those for SCSI adapters and network
adapters) are not included in the installation kernel."

Which means that if the installation kernel that you are using does have the
SCSI modules, you should just load the parameters during the process of
loading anaconda.

When the RHEL loads, the first phase of the installation, you should use the
SCSI parameters there!
If nothing happens, this means that the SCSI drivers that you need are not
in the installation kernel.

I recommend using the latest release of the version of the RHEL you are
trying to install.

Also check page number 106 (20-30) of the pdf that Roger posted, on SCSI
options.

I hope these guidelines will help you solve the problem.

Regards,

Filipe Miranda
