The following series of commands demonstrates how to set the PVID of an AIX disk to a specific value like “0123456789abcdef”:
Note:  Setting PVID like this should be avoided normally. It may cause unwanted consequences in your environment.

# DISK=hdisk2
# chdev -l $DISK -a pv=clear
hdisk2 changed

# lspv | grep hdisk2
hdisk2          none                                None

# perl -e 'print pack("H*","0123456789abcdef");' > /tmp/pvid

# cat /tmp/pvid | dd of=/dev/$DISK bs=1 seek=128
8+0 records in.
8+0 records out.

# rmdev -dl $DISK
hdisk2 deleted

# cfgmgr

# lspv | grep $DISK
hdisk2          0123456789abcdef                    None

# mkvg -fy testvg hdisk2
testvg

# crfs -v jfs2 -g testvg -m /testfs -a size=20G
File system created successfully.
20970676 kilobytes total disk space.
New File System size is 41943040

# mount /testfs

# lspv $DISK -l
hdisk2:
LV NAME               LPs     PPs     DISTRIBUTION          MOUNT POINT
fslv03                160     160     00..108..52..00..00   /testfs
loglv02               1       1       00..01..00..00..00    N/A

Again , This task not recommended to manually, it’s prefer to let system make it automatically
