As you can see the partition tables of your disks don't match!

Do the following steps:

First copy the partition table of the original disk to the mirror with the command:

# prtvtoc /dev/rdsk/original | fmthard -s /dev/rdsk/mirror

Check with "format" again and you will see that the partition table looks exactly the same now.

Then create at least 2 state database replicas on both disks with the command:

# metadb -a -f -c2 /dev/dsk/SliceForMetadb /dev/dsk/SliceSorMirrormetadb

Then start building your metadevices again.

HTH.
