hm, this meant only that the reason is not something in AIX but in your machine. "wrong" was probably a stretch. For instance, hdisk devices (which are similar insofar as several equivalent ones are usually there) aren't changing every reboot either.
Maybe there is some script which deletes and reconfigures the devices upon (re)-boot time for some unknown reason?

mkdevalloc
mkdevalloc(1M) System Administration Commands mkdevalloc(1M)
NAME
mkdevalloc - Make device_allocate entries
SYNOPSIS
/usr/sbin/mkdevalloc
DESCRIPTION
The mkdevalloc command writes to standard out a set of device_allocate(4) entries describing the system's frame buffer, audio and removable
media devices.
The mkdevalloc command is used by the init.d(4) scripts to create or update the /etc/security/device_allocate file.
Entries are generated based on the device special files found in /dev. For the different categories of devices, the mkdevalloc command
checks for the following files under /dev:
audio /dev/audio, /dev/audioctl, /dev/sound/...
tape /dev/rst*, /dev/nrst*, /dev/rmt/...
floppy /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
removable disk /dev/sr*, /dev/nsr*, /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
frame buffer /dev/fb
All entries set the device-minimum and device-maximum fields to the hex representations of ADMIN_LOW and ADMIN_HIGH, respectively. The
device-authorization field is set to solaris.device.allocate, except for the framebuffer entry, where it is set to *. The device-name,
device-type and device-clean fields are set to the following values:
device-name device-type device-clean
audio audio audio audio_clean_wrapper
tape mag_tape_0,1,... st st_clean
floppy floppy_0,1,... fd disk_clean
removable disk cdrom_0,1,... sr disk_clean
frame buffer framebuffer fb /bin/true
