Hi All,



I am trying to mirror an openBSD4.2 install on a Sun v20z box. That box
has LSI 1030 internal raid controller. According to the LSI manual, I
reboot the box into the LSI tool by pressing Ctrl-C while booting. When
I try to mark the primary disk, it says "Can't keep data. Incompatible
partition". So, it could not mirror a disk with already installed
openBSD4.2 partitions.



I did a research and found the similar problem already reported for
Linux installations, and Sun released a workaround for it. However, I
cannot find anything about openBSD installations.



So, has anyone run into that problem? If so, how did you succeed
mirroring an openBSD4.2 disk on such a hardware platform?



Thanks,





Rami Sik

At present, I've got two LSI RAID controllers here running OpenBSD
("MegaRAID 150-6 SATA" and "MegaRAID i4" PATA).

Though I don't know about your specific controler (1030), the normal
answer is to create your logical drive in the controler setup and
*THEN* install the operating system.

From your description, it seems you're doing things backwards, namely
installing the OS on one drive and then trying to create a miror.
