how boot new partition from image catalog?

using VPM to create a 2nd partition on a power 7 system. Now I would like
to install V7R3 in that partition. When I use option 1=power on in the
"work with partition status" screen the IPL fails with B200 4158.

I am expecting to be able to IPL from an image catalog. Can I do that?

Have a trial version of V7R3. Downloaded as a set of .UDF files. Added
the I_BASE .UDF file to an image catalog. Can I boot and install from that?

CRTIMGCLG IMGCLG(V7R3BASE) DIR('/home/v7r3') CRTDIR(*NO)
ADDIMGCLGE IMGCLG(V7R3BASE) FROMFILE('/home/v7r3/B_GROUP1_01_IBM_i_R
S_730-00_lcd8_2288_00.udf') TOFILE(*fromfile)
LODIMGCLG IMGCLG(V7R3BASE) OPTION(*LOAD) DEV(OPTVRT01)
VFYIMGCLG IMGCLG(V7R3BASE) TYPE(*other)
Image catalog V7R3BASE, type *OTHER verified.

I question if I am even setting up the image catalog correctly. Got this
error on the VFYIMGCLG comand when I used the TYPE(*UPGRADE) option:

VFYIMGCLG IMGCLG(V7R3BASE) TYPE(*UPGRADE)
Volume I_BASE_01 added to optical device.
