To remove a dead disk from a VG you have to use 'vgreduce -f'.

However, your other problem is going to be that the system still thinks that the disk is part of a mirror set.

Here is what I would do:

1) Replace the dead disk

2) Use 'ioscan' to make sure the disk is now alive

3) Run 'vgcfgrestore' on the replaced disk.

4) Run 'mkboot' and 'mkboot -a' to replace the boot areas of the disk.

5) Reactivate VG00 so that the VG sees the disk

6) Run 'vgsync vg00' to resync your mirrors.
