Guys,
I have no battery backed cache. I even don`t need it for current
configuration.
Why controller's cache matters if current write speed is 0.5 Mb/sec ?
In windows (prior installation OBSD) I noted ~ 80 MB/sec write speed
on same configuration.
My current test (after deleting array and instal
This is mpi so this response doesn't seem accurate as they don't have
battery cache etc.

Did it, but looks something wrong:
1. scsi -f /dev/rsd0c -m 8 -P 3 -e
2. Opened vi where I edited WCE: 0 to 1 and and saved file

Marco,
thank you for your super fast answer!
As I understood you told that I need to delete raid logical disk, and
use two separate disks.
1. I deleted array and selected disk 1 to be boot disk in LSI configuration.
2. During installation I was able to see 2 disks (as expected), so I
installed O
Download "Smart Start" CD from HP site. Boot this CD and configure SCSI
adapter an RAID settings. There is far more options to configure, than
from SCSI adapter BIOS. Btw if you have battery backed cache, you can
switch on write cache. You should also download and boot "Firmware
CD"...
I.
On Tue,
Something like:
# scsi -f /dev/rsd0c -m 8
change WCE: 0 to WCE: 1

Marco,
thank you for your super fast answer!
As I understood you told that I need to delete raid logical disk, and
use two separate disks.
I did it and I'm installing OpenBSD on first disk right now.
I have question for you - how should I "enable write cache on them
using scsi" ?

Thanks!
Your disks have write cache disabled. I started on a diff but hit a
roadblock and didn't get back to figuring this out. Currently the only
way to "fix" this is to undo the raid volume and let the actual physical
disks show up. Then enable write cache on them using scsi. Not really
