I got it to work (raid 0, raid 5) with the new raid patches and
raidutils (Get potato source package and build for slink)

I had a couple of problems with crashes, oopses and the like so i would
currently not recommend relying on working raid on sparc ...

Also i used the "qlogicpti" SBUS Wide SCSI Controller which seems
to have some problem with many Drives on the same bus or the kind.
I happens to me that i was not able to resync a raid5 with 6 drives
in an external Sun Multipack.

The same Multipack (Same cables etc) workes flawlessly on my i386 
Linux box with an NCR based PCI Wide controller. (Same raid 
patches + raidtools + same kernel version)
