AIX Logic Volume

Read the error message creaful to understand where the problem is -- MAX pps per PV is not big enough or MAX LPs

0516-1162 extendvg: The Physical Partition Size of 256 requires the
creation of 1300 partitions for hdisk15.  The limitation for volume
group oeclconv_vg is 1016 physical partitions per physical volume.
Use chvg command with -t option to attempt to change the maximum
Physical Partitions per Physical volume for this volume group.
