Greetings, Dual Opteron with Supermicro H8DAR-T mobo including Adaptec Marvell Hercules 2 SATA hardware RAID controller (MV88SX6041 4-port SATA II PCI-X Controller); 2 disks. We have no other 64-bit machine. SciLx can't see anything on that SATA disk controller without the aar81xx.rhel4qu1.x86_64.img driver from supermicro. But that locks the box into SL4.1 & kernel 2.6.9-11. It's said that sata_mv driver, which should support MV88SX6041, is in later SL kernels - yes, it's in 2.6.9-42 - but yum update this box's kernel to 2.6.9-42 & try to boot - no joy, no drives seen. Is there a way to have this box use a later kernel, by some simple yum upgrade/update, that frees us from the aar81xx.rhel4qu1 driver? (rhel4qu1 is the latest version there is) (total novice at initrd / kernel compile stuff; pointers to very straightfoward howto are welcome) Is there truth to the rumor that the sata_mv driver does not support MV88SX6041, or does not support it well? There is some howto w.r.t this wretched SATA ctrlr for FC3/4 which is helpful but complicated (to me). It's said FC5 works out-of-the-box with this wretched SATA Ctrlr. The 40Rolling x86_64 is 2.6.9-42 but there are no ISOs yet. (Plus, we'd be a bit nervous of using Rolling.) All the rest are at best 2.6.9-34 but no sata_mv there. Grateful for help. PS Global applause to Troy Dawson, Connie Sieh, & all the rest of the SL crew. SL is an awesomely pleasant OS to use & support. You deserve some sort of global recognition!!
