Dear All,

After read some paper and man page of vinum, i still have some difficulty.
I have 2 disk identical disk that i want to mirrored 1:1 (RAID-1), first 
disk label is

/#disklabel /da0
--snip--
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:  1024000        0    4.2BSD     2048 16384    90   # (Cyl.    0 - 63*)
  b:  1048576  1024000      swap                        # (Cyl.   63*- 129*)
  c: 35840952        0    unused        0     0         # (Cyl.    0 - 
2230*)
  e: 33768376  2072576    4.2BSD     2048 16384    89   # (Cyl.  129*- 
2230*/)

/#cat /etc/fstab
/dev/da0s1b             none            swap    sw              0       0
/dev/da0s1a             /               ufs     rw              1       1
/dev/da0s1e             /usr            ufs     rw              2       2
/dev/acd0c              /cdrom          cd9660  ro,noauto       0       0
proc                    /proc           procfs  rw              0       0/

my question is ;
how to prepare second disk layout (ad1) and rename it,  so it can user 
RAID-1 and boot from the second one if ad0  fail ?
Please help me.
