Oracle X2-4 not showing all drives

[lists at alderfamily.org]

This is on the bare hardware, that you installed RHEL correct?  The reason I
ask that is because this hardware platform is generally known as a
virtualization platform.  But it sounds like you are seeing a single
'logical' drive.  This server-class hardware should have a raid/drive
controller presenting the logical disk to the OS.

 

I would check your POST for options to configure a Raid/Disk controller.  It
might be defaulting to a mirrored set; which would only present the OS with
a single logical drive.

 

That is the first thing I would check at least.

 

Also, why aren't you installing on RHEL6?

Subject: Oracle X2-4 not showing all drives

 

 All, I am in the process of building two Redhat Servers on Oracle X2-4
hardware. Redhat version is 5.7. Both systems have two scsi hard drives,
however I can only see one drive. Is there a command similiar to "format"
from the Solaris world that will list out all available disk drives? 

 

If I use fdisk -l, I only see sda1 and sda2 which is the drive that Redhat
was installed to. I don't see anything listed in /dev similiar to sdb or hdb
which is the way I understand it to work. I am in the process of learning
Redhat after a long background with Solaris.
