I also have a Quantum Lightning 730S:

scsi0 at scode14 ipl 4: 32 bit dma, async, scsi id 7
sd0 at scsi0 slave 0: <HP, 2213A, C023>
sd0: 1457 cylinders, 16 heads, 1296512 blocks, 512 bytes/block
sd1 at scsi0 slave 1: <COMPAQ, M2694ES-512, 952B>
sd1: 1819 cylinders, 15 heads, 2051000 blocks, 512 bytes/block
sd2 at scsi0 slave 2: <TOSHIBA, CD-ROM XM-3301TA, 0272> (SCSI-2)
sd2: CD-ROM, drive empty
st0 at scsi0 slave 3: <ARCHIVE, VIPER 60   21116, -007>
sd3 at scsi0 slave 4: <QUANTUM, LIGHTNING 730S, 241E> (SCSI-2)
sd3: 3658 cylinders, 4 heads, 1431760 blocks, 512 bytes/block

...and I have noticed this problem ... for quite some time now.  Whenever 
I reboot my 380, I have to power-cycle it, and hit the spacebar during 
self-test so that the BOOTROM will scan all disks.  Then, and only then, 
will my 730S be found during boot.  I find this quite annoying...

I've been meaning to fix it for about a year, but up until a short time 
ago, I couldn't get docs on the Fujitsu SCSI chip used in the hp300.  I 
have docs now, so it's a matter of sitting down and seeing where it loses.

I suspect that the 730S is cutting some corner somewhere.
