Need to remove mirroring in Logical Volume and remove a PV

Issue

• We have a mirrored logical volume and need to remove one PV from the logical volume.

   --- Logical volume ---
    LV Name                /dev/oravg/oralv
    VG Name                oravg
    LV UUID                oXzD0c-e7Tq-ZDAx-Uqdc-Xl8w-1Jxd-8e1awA
    LV Write Access        read/write

    # open                 1
    LV Size                29.90 GB

    --- Physical volumes ---
    PV Name               /dev/emcpowere
    PV UUID               8CK9iK-Vg04-Gg2L-Pec2-n2hn-2xN3-PsrOAA
    PV Status             allocatable
    Total PE / Free PE    7679 / 23
  
    PV Name               /dev/emcpoweray
    PV UUID               elVCYt-Y4y0-eTQ3-8D4D-J9cj-KVwT-3c1eAa
    PV Status             allocatable
    Total PE / Free PE    7679 / 24
  

  We need to break mirroring and remove one of the two Physical volume /dev/emcpoweray without any data loss. Please suggest how to do this change.
