AIX unmirroring while mirroring in background

Hi,

by mistake I ran unmirror while mirroring was running in the back ground. anyhow the unmirror operation failed with the following

0516-076 lreducelv: Cannot remove last good copy of stale partition.
        Resynchronize the partitions with syncvg and try again.
0516-922 rmlvcopy: Unable to remove logical partition copies from
        logical volume oradata2_lv.
0516-1135 unmirrorvg: The unmirror of the volume group failed.
        The volume group is still partially or fully mirrored.

still the mirroring is in process now.

would it have effected the VG in anyway?
