SUMMARY: Mirroring root and swap with Online Disksuite

The problem is solved. I recieved several replies and although they
did not contain a solution they did show that what I was doing should
have worked. Then I rmembered that, due to a conflict with the Sun
SBus expansion chassis (xbox), a while back I had reconfigured the
metadisk devices to use major number 14 instead of 4. Both xbox and
disksuite are configured to reuse the number that had been assigned to
cgone a long time ago. Apparently nobody at Sun thought that someone
would want to use both products on the same machine. :-(

The tipoff came when I realized that for root mirroring, you have to use
devide md0a. Thus it must be hardwired into the kernel to use major
device 4, minor 0. So I put the md drivers back at 4 and xbox at 14 and
both seem to be working now.

So in the end, it was my own damn fault (don't you just hate that?).
