I'm using software RAID with all disks setted up as RAID 0 over a P400.
I read in P400's documentations that it is recommended to distribute the disk raids between ports of the controller. So I combine mirrors between disks 1-4 (attached to one port) and 5-8 (attached to the other).
I have a "/boot" partition mirror and also a "/" partition mirror between disks 1st and 4th.
The problem is that I want the MBR replicated as well, and so, I must install grub to the 4th disk but when I remove 1st disk, 4th doesn't boot and a red illegal op code screen splashs.
I'm I doing something wrong or is it true what I read somewhere: guess that removing 1st disk, Smart Array tries to boot forcedly the second one, and then I suppose I must install grub on all disks chainloading to the 4th disk
I there any other easier/professional solution? Maybe changing the disk boot order inside the smart array through BIOS or something similar?
Thank you all!

Setup the Smart Array as RAID 1+0 or RAID 5 and don't worry about software mirror.

Re: Smart Array P400, Boot Order, Software RAID, Mirroring /boot partition, Grubs and chain-loading
Well, I didn't explained it well. I must did it through software RAID because of a particular requirement on the upper software level. I know it's not as much profitable.
One thing I tried to play with, in order to make a workaround was to make RAID partitions through the ACU but I had no success, since I didn't find a way to put an array between different partitions of each disk. I mean, for instance, I want disk1 with 2 partitions, one mirrored with disk2 and the other with disk3. ACU only lets me group the array between disk1,2,3 but then there is no way of assign logical drives among a subset of them, I just can make logical drives on the entire array.
By the way, they are not configured as an 8-disk RAID 0, but an 8 x 'a Raid0 LogicArray of one disk'.

Re: Smart Array P400, Boot Order, Software RAID, Mirroring /boot partition, Grubs and chain-loading
Maybe I didn't understand what you are doing, but IMHO the controller provides the right RAID level for you:
http://h18000.www1.hp.com/products/quickspecs/13201_div/13201_div.html
...
The HP Smart Array P410 is HP's PCI Express (PCIe) 2.0 Serial Attached SCSI (SAS) RAID controller. The low profile, half height card has 8 ports and utilizes DDR2-800 memory. The P410 is ideal for RAID 0, 1, 1+0, 5, 5+0 and can be upgraded with a minimum 256MB cache module, battery kit (for BBWC), Flash Backed Write Cache (FBWC), and Smart Array Advanced Pack license key for RAID 6 (ADG), & 6+0.
Hope this helps!
Regards
Torsten.

SolutionDoing this should meet your upper software requirement for software RAID, and because you've setup the controller in a fault tolerant RAID configuration you don't need to worry about having to manually replicate the MBR as the hardware RAID will take care of it.
