Hi,

Trying to install 4.2-release (and snapshot) on an IBM xServer 345 with 
ServeRaid/5i controller.

I've used the Linux based bootable CD from IBM and created an array with 
RAID1
Everything seems fine but when I boot up the OpenBSD cd it does not see 
any disks.

dmesg shows:

pci5 at pchb7 bus 8
"IBM ServeRAID" rev 0x00 at pci5 dev 2 function 0 not configured

Reading the man page for ips(4) I read this:

-----

Although the controllers are actual RAID controllers, the driver makes
them look just like SCSI controllers.  All RAID configuration is done
through the controllers' BIOSes.

-----

Can anyone shine some light on how to actually make this controller work 
with OpenBSD?
Or am I overlooking something obvious?

Thanks!

Matt

The "not configured" means the device is not claimed by any
kernel driver.  In this case it seems that ips(4) is in
the GENERIC kernel but not the ramdisk kernels used for installation.

Not quite sure if this is a case of the driver not being ready
or just an oversight.

ips is not included in the ramdisk kernels.

I had the same problem and my solution was to copy the two lines for ips 
from /usr/src/sys/arch/i386/conf/GENERIC to 
/usr/src/sys/arch/i386/conf/RAMDISC_CD and then build a release.

Thanks, that worked.

I had never build a release before so I did it as described  in the FAQ 
[1] on a different non-important machine,
including a complete build of the userland binaries. Then I build a 
release from that.
Eventually I did end up with the ips(4) enabled  cd42.iso in the 
/usr/rel directory.

Reading release(8) I could not find if there was a shortcut in doing this?
Could one just build parts of the system needed for cd42.iso ?

Thanks again,
Matt

grange@ the author of the driver says there is still a data corruption
bug in ips, so rather than enabling it on ramdisks I'll disable
it in GENERIC tonight.

Am I understanding correctly grange's info made you decide the ips 
driver should not be used _at all_ ?
I was planning to put this box in production today but the 'data 
corruption' part got me worried.

Is there more info available on what the author said?
And is there anything we can / should do to accomodate a fix?

Thanks.

"unfixed data corruption bug" is the extent of my knowledge,
I don't think grange currently has the time to work on this further
right now.
