Since you didn't get an OSA activation error, I suspect that you're
connected to the wrong OSA. See below.

It is indeed possible to create different device numbers on different
LPARs for the same chpid, but it takes extra effort and it's unusual to do
so. Since you ask how to change it, I assume that you're not the person
in charge of the I/O configuration of the box. Only they can change it.
An OSA on chpid 0 at device number 0 would appear in the I/O configuration
as something like
CHPID PCHID=170,PATH=(CSS(0,1,2,3),00),TYPE=OSD,SHARED,CHPARM=02
CNTLUNIT CUNUMBR=0000,PATH=((CSS(0),39),(CSS(1),39),(CSS(2),39), X
(CSS(3),39)), X
UNIT=OSA
IODEVICE ADDRESS=(0000,32),CUNUMBR=(0000),UNIT=OSA,UNITADD=00
IODEVICE ADDRESS=(00FE),CUNUMBR=(0000),UNIT=OSAD,UNITADD=FE
To make it device 0 on LPAR 1 and device 1000 on LPAR 2 requires a bunch
of extra coding that few people bother with. The QUERY PATHS command will
tell you the chpid. If QUERY PATHS 000 on LPAR 1 and QUERY PATHS 1000 on
LPAR 2 show the same chpid, you're on the right track.
Here's what my OSA looks like. It has the same addresses on all LPARs.
CHPID PCHID=291,PATH=(CSS(0,1,2,3),53),TYPE=OSD,SHARED,CHPARM=02
CNTLUNIT CUNUMBR=6640,PATH=((CSS(0),53),(CSS(1),53),(CSS(2),53), X
(CSS(3),53)), X
UNIT=OSA
IODEVICE ADDRESS=(6640,32),CUNUMBR=(6640),UNIT=OSA
