Hello, I recently purchased a X7DCA-3 motherboard and have 4 SATA hard drives attached to an SAS port (LSI 1068E). I also have one hard drive attached to a SATA port. I booted into DOS to see if it recognizes all the hard drives, and unfortunately it only registers the SATA drive (not too shocking). I loaded on OpenSolaris and it still only recognizes the one SATA drive.
There is nothing in the BIOS about the SAS port. Now if I hit ctrl-M it takes me into a RAID software screen where I can set up a RAID array. I figure the reason the OS's aren't recognizing the 4 hard drives is because the SAS controller views them as not set up. In the RAID software however there is no way to set them to individual drives or to a JBOD mode.
I am wondering if anyone has purchased and used these boards? Do I need to try and update the LSI or motherboard BIOS (I am always apprehensive about that.)
I want to use the 1068E because it then gives me a lot of room to add more hard drives should I want it. As it is I am using 2-3 SATA ports out of a total of 6. Also from what Ive read the 1068E is a better controller in terms of performance.
I feel uncomfortable about assigning a single hard drive to be RAID 0 as I am afraid it is doing something unsavory in the background. Ive tried setting it up like that and OpenSolaris does indeed register the new drives. So I think its a matter of the RAID controller marking the drives as not setup, and since there is no JBOD mode I guess Im out of luck with this. Ill try updating the BIOS
Well it doesnt complain but having a single hard drive in RAID 0 is a contradiction to the very core of RAID 0. As such I don't know how the RAID card is handling that. It assigns a stripe size and other parameters associated with RAID to this single hard drive.
