kernel boots wrong disk

[Frank Wille <frank%phoenix.owl.de@localhost>]

Hi,

I have my original 6.1.5 system with a RAID-1 configuration on sd0 and 
sd1. Now I have installed 11 on a new disk in sd2 (sunlabel, disklabel, 
newfs, extracting sets, installboot, /ofwboot, MAKEDEV etc. - I think I 
didn't forget anything):

sun# sunlabel rsd2c
sunlabel> P
a: start cyl =      0, size =  8355096 (823/0/0 - 4079.64Mb)
b: start cyl =    823, size =  8355096 (823/0/0 - 4079.64Mb)
c: start cyl =      0, size = 143143200 (14100/0/0 - 69894.1Mb)
d: start cyl =   1646, size = 126433008 (12454/0/0 - 61734.9Mb)

aaaabbbbbddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc

sun# disklabel sd2
# sd2:
type: SCSI
[...]
#        size    offset     fstype [fsize bsize cpg/sgs]
 a:   8355096         0     4.2BSD      0     0     0  # (Cyl.      0 - 
   822)
 b:   8355096   8355096       swap                     # (Cyl.    823 - 
  1645)
 c: 143143200         0     unused      0     0        # (Cyl.      0 - 
 14099)
 d: 126433008  16710192     4.2BSD      0     0     0  # (Cyl.   1646 - 
 14099)

I have also written the fstab using sd2:

sun# cat /mnt/etc/fstab
/dev/sd2a       /               ffs     rw,log                          1 1
/dev/sd2b       none            swap    sw,dp                           0 0
kernfs          /kern           kernfs  rw
procfs          /proc           procfs  rw
ptyfs           /dev/pts        ptyfs   rw
tmpfs           /var/shm        tmpfs   rw,-m1777,-sram%25


Then I try to boot the netbsd-11 kernel from disk2 (sd2):

{0} ok boot disk2:a /netbsd -s

Er... what? Why does it select a RAID-frame from completely different 
disks? Is this a known bug?

What can I do? Remove the disks? But I want to set up a new RAID system 
on them using my current boot disk. :|
