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

  Found duplicate PV e32c4FWG0wWpikEDk1O76SfLQ1n1NQoR: using /dev/mapper/eql-0-8a0906-18a0eb801-d0f000000054e679-omadvnfs01-data01d not /dev/mapper/eql-0-8a0906-b560eb801-857006ad19b4f46a-omadvnfs01-data01c

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