I make no claim to expertise, but I *think* you want:

dmsetup remove /dev/vg_data01h/lv_data01h

I use this for cleaning up VG/LVs when I kick out a USB based PV by
accident.

Thanks for this.  It cleaned them up fine and I was able to move forward with that one.  However, I am trying to recreate the PVs and pvdisplay is giving me these errors which has me concerned:

  Found duplicate PV e32c4FWG0wWpikEDk1O76SfLQ1n1NQoR: using /dev/sdag not /dev/sdq

The last two volumes are data01b and data01c which are referenced in these errors.
