I am trying to build a file server with 1 x 80 GB main drive and 4 x 500 GB SATA drives in RAID in a Supermicro 3U server. I found out the hard way that Centos 4.2 does not have a driver for the onboard Marvell H2 controller the drives are connected to.
Supermicro techs sent me aar81xx.rhel4qu2.i686.img as an img file. I used dd to copy to a floppy and dd confirmed successful write.
I booted Centos 4.2 and chose linux dd. When prompted I inserted the floppy and the driver was loaded. However, when it came to partitioning the drives, no drives could be found. I tried loading the driver during install using F2 for "other drivers", still no go.
Has anyone had success with this process or am I doing it wrong? The img file can be downloaded from http://www.masonc.com/aar81xx.rhel4qu2.i686.img if anyone would like to test it.
I would strongly recommend *not* using that SATA controller at all. Your problems with it aren't going to end once you get the install done. The driver from SuperMicro is not going to track the vendor kernel closely at all, so you'll be forced to not install kernel updates. Also, given that the driver isn't in the kernel, its performance and stability are unknown.
On my compute nodes with SM boards, I just threw a 3ware 8006-2 in each and a single drive. On my servers, I used the same controller and a pair of 74GB WD Raptors as a hardware RAID1. The 3w-xxxx driver is rock solid and has been in the kernel for a long while.
What controller are you using for the 4 drive RAID array? Would it be possible to boot off that?
