Hello all,

So, we are upgrading a system in our server room to RHEL6.2. It uses a RocketRAID 2710 RAID 1 controller.

When I installed RHEL6 initially, it wouldn't see the RAID1 "hardware" array supplied by my RocketRAID controller, and was reporting "no usable disk." So I had to use some black magic and driver manipulation in order to get the install to work.

I installed RHEL6.2 on a virtual machine and downloaded the RocketRAID rr272x_1x custom drivers and compiled them, put them onto a USB stick, and then during the RHEL6.2 install got into a command prompt and loaded up the driver:

> cp rr272x_1x.ko /lib/modules/../scsi/rr272x_1x.ko
> depmod -a
> modprobe rr272x_1x.ko

And the installer was then able to see my disk array-- great. Install proceeded as normal, then it went to reboot, and:

"dracut warning: LVM * not found"

Back to square one. I guess I thought by adding the driver to the boot loader kernel it would pass it on, but apparently this is the age old "chicken and the egg" problem at it's finest. So now, I'm trying to figure out the easiest way to combat this. I know I can supply an initrd using PXE, but I don't really want to go that route. Also, this system has no spare boot drive, which is also probably slightly bad form.

Does anybody have any experience with this sort of thing?

Thanks!

Here is a screenshot of the boot with "quiet" taken out of the boot string. You can see where it fails.

What about the ramdisk?

[edit]

After researching this extensively, I've decided to just disable my RAID controller and setup software RAID using RHEL.

Thanks.
