Ultra 10 OBP can't see SCSI drives

807557 Member Posts: 35,835
I'm trying to get my Ultra 10 to boot off a SCSI drive. I've tried several controllers (SYM21002, SYM21003, and another 53c896 card) and several drives, but probe-scsi-all returns nothing. If I boot off an install CD (the CD drive is still IDE), I can see the drives and install an OS on them, but when I reboot it still can't see the drives at the ok prompt. I've tried OBP 3.31 and 3.29 with the same results in both. Any idea how I can get it to boot off a SCSI drive? Or, failing that, is it possible to boot a bootloader on an IDE drive, which then boots off the SCSI drive?

    you say you can install with scsi drives, but on restart it won't boot? what is the U10 looking for? did you try boot disk ? the U10 may be looking to boot off the network or somewhere off..

    I don't recognize the chip numbers... are they supported by Sun? I have only used Sun-branded scsi cards--- 375-0005 comes to mind...

    Sounds like the SCSI card in question doesn't have FCode on it. See the following:
