Do a lvdisplay -v to look up the broken disk. You should see either the name or the pvkey.

If the disk shows up with a /dev/dsk/... you can remove the mirroring with:
# lvreduce -m 0 /dev/vg##/lvol# /dev/dsk/....

If the disk shows up only with its pvkey:
# lvreduce -m 0 -k /dev/vg##/lvol# pv_key

Hope this answers your question.
