Red Hat Enterprise 4 on Dell PowerEdge 1950 : Help needed

cavster63 · 09-04-2007, 11:02 AM

Hi I've read a previous thread almost like my issue, but it was relating to the Dell PowerEdge 1900 and not the PowerEdge 1950, which I really do not know the difference.

My problem is that I'm trying to load the megaraid_sas-v00.00.02.03-1-rhel40-all.img from Dell, and the server I have did not come with a RHEL OS or any OS for that matter. So I'm using the RHEL version 4 CD1 (for 64-bit AMD64 and INTEL EM64T) to boot up the server so I can load the needed driver. But it's not working, and I think part of the problem is the server is reading the thumb drives as being multiple partitions and I've tried a variety of sizes for the flash drives. I've also tried to use a floppy drive 3.5 inch, but the driverr is 1.4 megs in size so the 3.5 floppy does not have the room needed for the driver.

I get to the last step where I select the driver needed, but the install fails, and I get this error saying "failed to mount drive". Any positive input would be greatly appreciated.

Have you tried just loading RHEL without the official driver?

I installed in an indirect fashion (using OSCAR cluster toolkit from a 2950 head node) so I am not sure if the drivers are necessary for the initial install. If you can get it to install, boot into rescue mode using the install cds and try this modprobe.conf file if it kernel panics on boot.

Code:

alias eth0 bnx2
alias eth1 bnx2
alias scsi_hostadapter mptspi
alias scsi_hostadapter1 mptspi
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
alias scsi_hostadapter2 mptsas
alias scsi_hostadapter3 mptfc

These are all RHEL4 drivers though, so I think it ought to be possible without the Dell official driver.

ymmv of course.
