Howdy
I have a Dell PowerEdge 2950-III (BIOS: 2.6.1) with a PERC6i (FW:
6.2.0-0013, DRIVER: 00.00.04.08-RH2) that is built into a single RAID5
array happily running CentOS 5.4, and has been running happily for
some time. We use it to dump impressions data and DB snapshots to.
(Possibly useful info: we use LVM and we're at kernel 2.6.18-164.11.1.el5)
I recently installed a RockerRAID 2314 PCIe card
(http://www.highpoint-tech.com/usa/rr2314.htm) and got an eSATA JBOD
chassis (http://www.rackmountmart.com/html/SA4001.htm) to add a little
more cheap storage for "less important" data.
Brought the RocketRAID's BIOS up to date (v2.5), built the latetst
driver from source, loaded it and everything was peachy. I built a
RAID5 array with a spare on the live system with the Web-based
Management System (v1.4-10), formatted and mounted it. Yay.
We hadn't begun really using the volume yet when I rebooted the
machine a few days later for a memory upgrade and it hung on boot at
the following screen:
Booting 'CentOS (2.6.18-164.11.1.el5)'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.18-164.11.1.el5 ro root = /dev/obnas/root
[Linux-bzImage, setup=0x1e00, size=0x1d6b1c]
initrd /initrd-2.6.18-164.11.1.el5.img
[Linux-initrd @ 0x37cb5000, 0x33a982 bytes]
So, I power cycle the machine, went into the Card's BIOS and delete
the array and it booted fine.
I think the RocketRAID is confusing GRUB or something like that when
it has a bootable volume.
So I went through the all the BIOS settings, boot orders, array
settings on the RocketRIAD BIOS etc.. no luck.
I have a ticket open with HighPoint (makers of the device) but it is
the weekend so I don;t expect a reply for a while. I've got a crazy
week up ahead before I am out of the office for surgery so I want to
try to get this done.
My gut feeling is that it is a common enough problem with add-on cards
that have their own BIOS and i am either dense or an awful researcher.
I would greatly appreciate anyone's insight.
Any thoughts?

The issue is the rocketriad is a FRAID or fakeraid and you need a binary
kernel mode driver for it to work. If you want more port get a non-raid
sata card or either get another perc, 3ware, areca.
