in your case metareplace will already do a resync and this is copying files from mate disk to new replaced disk.
All you have to do be careful about that the replacement disk must be partitioned to match the disk it is replacing before running the metareplace command.

If your disk is part of a two disk mirror you can lay out the partitions on the new disk with a one line command:

prtvtoc -s /dev/rdsk/good_disk_s2 | fmthard -s - /dev/rdsk/new_disk_s2

Here is an example:

# prtvtoc -s /dev/rdsk/c0t1d0s2 | fmthard -s - /dev/rdsk/c3t0d0s2
fmthard: New volume table of contents now in place.

Of course it is a good idea to do a prtvtoc -s on each drive before you pipe the prtvtoc command to the fmthard so you can see the layouts of each disk before you copy the info.
