since the lv is mirrored there should be no need to back it up.

The very very first step should be to run rmlvcopy to logically get rid
of the mirror on the failed disk. You are updating the vgda and odm so
it doesn't matter if the disk isn't spinning.

Do indeed remove both the hdisk and the pdisk associated with it.
Otherwise you'll have a pdisk with no hdisk assiciated to it. Last
step will be a mklvcopy use the the -k switch to sync as you build the
copy. Rembember RTFM
