The scsi drive lettering currently does this.. going sda to sdz, then sdaa,sdab,sdac, etc. The reason I need this is for using 4 x Highpoint 454 (hpt374 chipset, 8 drives each card) PATA cards in a software md raid, but of course it runs out of drive letters, and starts using funny characters such as dev/hd{ , and dev/hd\207 or something.. Beyond that, is there a way to merge hpt36x/hpt374 chipset support into libata, since libata uses scsi emulation with scsi drive lettering? It seems that is a goal of libata anyways, to support older PATA chipsets as well. And, yet one more option, would be to choose in the kernel config, whether you want the hpt374 driver to use ide, or scsi emulation.. currently, the tainted proprietary driver directly from highpoint uses scsi emulation.. surely it could merged as an option for the driver thats included in the kernel?
