There is no installgrub for sparc systems. There's some other bootloader process instead... See the ZFS Best Practices Guide, and the ZFS Troubleshooting Guide. I don't know what prvtoc is. Also, you should be glad you didn't have the hardware raid anyway. Because now you have to learn about ZFS software raid. The preferred and recommended thing to do is ZFS raid instead. There are many threads on this... Basically ZFS is able to do things that hardware can't do, because ZFS has knowledge of the disk blocks and filesystem, while hardware only has knowledge of the disk blocks. End result is: ZFS raid is both faster and more reliable than hardware raid. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
