Ah, yes, that is true. Running 'metadb' before all the above steps and
using metadb -d <slice> to remove any metadbs showing as 'unknown' ought
to take care of that. Then you would recreate them afterwards.
The other step that needs to be done before the metareplace is to copy
the partition table from the good mirror to the new disk with 'prtvtoc
/dev/dsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2' where t0 is the
good disk and t1 is the new one.
