New interesting ( I think) data: I set both diskdrives for spinup on powerup. As you might know the somewhat older DEC drives are set to wait for a spinup command. Newer ones are set for staggered spinup, this means they wait X seconds * the SCSI ID before starting their spindle. This to avoid high inrush currents, especially on raid arrays and in Storageworks shelves. Anyway, when booting the 3.0-current from the harddisk both da0 and da1 were spun up OK, and probed OK by the just booting kernel. When I used the bootflop / mfsroot flop for some reason this did not work, as far as sysinstall was concerned. sysinstall simply claimed "no disks found" or something similar. I just retried the whole floppy boot with the drives already spinning and now sysinstall finds the disks alright, both da0 and da1. I wonder if anybody ever saw this before. I think it is safe to assume you might DEC drives in Alpha machines, but maybe some SRMs do a startup of the disks on their own? I only remember that it took a boot from SRM to start disks, but I obviously have not seen all SRM and machine types. I'll try an install to see what happens..
