0516-030 lextendlv error trying to create a striped LV

Question:
Env:  AIX 4.1.4 (bos.rte.lvm 4.1.4.11)

Problem:  He is creating a striped LV on 3 disks, specifies 260 LPs
with MaxLPs=260, and gets this error:

0516-030 lextendlv: Illegal logical partition number.
0516-822 mklv: Unable to create logical volume.
0516-304 getlvodm: Unable to find device id 000011652edec037.3 in the Device
        Configuration Database.
0516-304 getlvodm: Unable to find device id 000011652edec037.3 in the Device
        Configuration Database.
0516-356 lvrelminor: Warning, the reldevno function failed.
0516-304 putlvodm: Unable to find device id 000011652edec037.3 in the Device
        Configuration Database.
0516-916 rmlv: Warning, can not remove logical volume 000011652edec037.3 from
        device configuration database.

Action taken:  When you create a striped LV, the system assumes that
the number of LPs is an even multiple of the disks you are striping
on (the stripe width).  If not, it automatically increases the number
of LPs to that level (i.e., in this case from 260 to 261).  Since MaxLPs
is set at a level below the new LPs value, it fails.

Bottom line:  Make the number of LPs an even multiple of disks, or
set the Max LPs afterwards.

Action plan:  Close.
