The clue is here. You are not running a kernel with raidframe enabled.
I'd advise to first play with this using a regular root file system,
and put some data on a raidframe file system, and only move to a
raidframe root after that. Having a raidframe root can be quite
confusing, since the boot device does not match the root device.
yes i am having some confusion here.
# uname -a
OpenBSD backupserver.hifxchn2.local 4.0 GENERIC.RAID#0 amd64
#
gives GENERIC.RAID
so I am running a kernel with raidframe enabled right?
I deleted the /var/run/dmesg.boot
halted the system.
restarted the system
in the dmesg|more after the earlier errors created while configuring
raid0 partition it says it is booting a raidframe enabled kernel.

I just wanted to create a degraded array using "wd1b" (another disk)
and wd2b ( fake entry no actual disk but /dev/wd2b entry exists )
I created a RAID file system type in "wd1b"
=======================================================================
16 partitions:
# size offset fstype [fsize bsize cpg]
a: 2097585 63 4.2BSD 2048 16384 328 # Cyl 0*- 2080

c: 234441648 0 unused 0 0 # Cyl 0 -232580
#
====================================================================
also a raid.conf for mirroring as said in the raidctl manpage
=============================================
# cat /root/raid0.conf
START array
# numRow numCol numSpare
1 2 0
START disks
/dev/wd2b
/dev/wd1b
START layout
128 1 1 1
START queue
fifo 100
#
========================
then gave the command to create the array using the -C option to force
its creation and then
=======================================================================
# raidctl -C /root/raid0.conf raid0
raidctl: ioctl (RAIDFRAME_CONFIGURE) failed
#
=======================================================
System messages
=====================================================

dkcsum: wd1 matches BIOS drive 0x81

raidlookup on device: /dev/wd2b failed !

RAIDFRAME: failed rf_ConfigureDisks with 2.

====================================================
So it says kernlized Raid Frame activated
Also
==============================================
# uname -a
OpenBSD backupserver.hifxchn2.local 4.0 GENERIC.RAID#0 amd64
#
===============================================================
So I am running a Kernel with Raid Frame enabled right?
I am using the -C option to create the array with raidctl so even if
/dev/wd2b is not present physically it should fore creating a degraded
array right?
Hope I make sense :-)
Thankyou so much for your help
Kind Regards
