I am no expert.  I don't even try to guarantee that you'll
not blow up your data (and the whole planet, too).  But AFAICT
/dev/LVM is created as needed with vgscan.  You did run vgscan
after the HW-change?

You did a vgcfgrestore on the new/replaced /dev/hdc PV?


PS: I'd still advise a current, working backup. :-)
