Re: DIsk Issue
You can do so. There is a vgreduce -f function that will let you get dead disks out of the volume group.
if the disk is really dead there is sometimes no way to get it out of the volume group.
Check the man page, it is not for the light of heart.

Re: DIsk Issue
See
http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad_WP.pdf
You simply deny LVM access to the disk, then swap the disk. (pvchange -a n ...).
Hope this helps!

Torsten.
