Adding more disks to our '780 here running More BSD 4.3 has caused
a problem. The system will not boot with more than 2 drives powered on.
Configuration:
Vax-780 (FP, 8mb)
Emulex Vmaster w/ (1) SC-7000/B3, and (1) SC-780
SC-7000: (3) Fuji 2298 (68 sector)
SC-780: (1) CDC 9775 (mapped)
A bootable root is on both the Fuji drive 0 and the 9775. If either
are booted with more than 2 total drives powered on (any combination)
then Unix will hang after the device probe messages and the final
root fs type message:

mba0 at tr8
hp0 at mba0 drive 0
hp0: 2298
hp1 at mba0 drive 1
hp1: 2298
hp2 at mba0 drive 2
hp2: 2298
mba1 at tr9
hp3 at mba1 drive 0
hp3: 9775
mba2 at tr10
ht0 at mba2 drive 0
tu0 at ht0 slave 0
root fstype ufs
...Unix hangs forever...
As stated, if only hp0 2298 and the 9775, or any other drive is powered
on, things boot fine. Similarly, if the 9775 is primary, and any
other (only) drive is on, things are ok.
The following configuration lines have been tried, with identical
results:
config vmunix root on hp
config vmunix root on hp swap on hp0
config vmunix root on hp swap on hp0 and hp1
config vmunix root on hp swap on hp0 and hp1 and hp2...
The following should also be mentioned:
The initial file systems were created as follows with
these strange results.
After hardware formatting the (3) 2298's, they were formatted
with the Unix format program. The 9775 was booted, and all three
drives were found as hp1,hp2 and hp3. Each was given a
'disklabel' as type '2298'. Newfs was performed as necessary.
The problem now occurs on the next reboot. If I reformat (unix)
2 of the 3 2298's, it will boot fine. Yet, once a disklabel
is given, the boot problem results.
I can't figure the problem, but the only clue is the disklabel information
and what Unix startup does with it.
Help...
