HELP: Howto update an lpp_source in NIM

I'm SO confused about the question of whether I can or cannot update an lpp_source with a bunch of patches. Someone I know who I think knows a lot about AIX and NIM says I should never do this. But I'm looking at the Redbook "NIM from A to Z in AIX 5L", which seems to describe exactly how to do it, in section 5.1. And now, I just read APAR IZ03167, which seems to say do NOT do this. Let me be more specific.

I have an lpp_source and SPOT that correspond to AIX level 5300-11-02-1007. All my servers are running that level right now. I just downloaded all the filesets to upgrade my servers to level 5300-12-02-1036. I have done an upgrade of one of my toy servers from the first mentioned level to the second, using these filesets in a "smitty update_all". This seemed to work perfectly.

My question is: How do I create an lpp_source and SPOT that correspond to the new level, 5300-12-02-1036?

The Redbook I mentioned describes in detail how to do a "smitty nim_update" on the lpp_source, using, apparently, that same set of filesets that I fed into the update_all. Then, it says, create a SPOT from this updated lpp_source, and you're done.

My friend, who seems to know all about NIM and AIX in general, says to never do this, because Bad Things Will Happen. She says the only reliable way is to order a full CD/DVD set of 5300-12-02-1036, and build the lpp_source from that. I think that's what APAR IZ03167 says, too.

Can anyone give me a definitive answer? I hate to have to order a full installable media set every time I want to install a minor upgrade. Is the Redbook wrong, and I really should never try update the lpp_source?

apmlabel

APMLABEL(8)						    BSD System Manager's Manual 					       APMLABEL(8)

NAME

     apmlabel -- update disk label from Apple Partition Map

SYNOPSIS

     apmlabel [-fqrw] device

DESCRIPTION

     apmlabel is used to update a NetBSD disk label from the Apple Partition Map found on disks that were previously used on Mac OS systems (or
     other APM using systems).

     apmlabel scans the APM contained in the first blocks of the disk and generates additional partition entries for the disk from the entries
     found.  Driver and patches partitions are ignored.

     Each APM entry which does not have an equivalent partition in the disk label (equivalent in having the same size and offset) is added to the
     first free partition slot in the disk label.  A free partition slot is defined as one with an fstype of 'unused' and a size of zero ('0').
     If there are not enough free slots in the disk label, a warning will be issued.

     The raw partition (typically partition c, but d on i386 and some other platforms) is left alone during this process.

     By default, the proposed changed disk label will be displayed and no disk label update will occur.

     Available options:

     -f  Force an update, even if there has been no change.

     -q  Performs operations in a quiet fashion.

     -r  In conjunction with -w, also update the on-disk label.

     -w  Update the in-core label if it has been changed.

SEE ALSO

     disklabel(8), dkctl(8), pdisk(8)

HISTORY

     The apmlabel command appeared in NetBSD 5.0.
