So you want an AIX versioned WPAR?

You cannot get rid of your oldies but goodies AIX 5.x? No problemo, create an AIX versioned WPAR. In our example, we create an AIX5.3 on a AIX 7.2 host lpar:

rendev -l hdisk1 -n aix53_rootvg
mkwpar -D devname=aix53_rootvg rootvg=yes -C -B /mksysb/mksysb0139 -t -n aix53 -l -O
[...]

Once created, you can then wait for the migration day with confidence. Once the source lpar has been shutdowned, configure the IP addresses into the wpar:

chwpar -N interface=en0 address=10.30.191.130 netmask=255.255.255.0 aix53
chwpar -N interface=en0 address=10.30.191.131 netmask=255.255.255.0 aix53
chwpar -N interface=en0 address=10.30.191.132 netmask=255.255.255.0 aix53

chwpar -N interface=en1 address=10.30.194.130 netmask=255.255.255.0 aix53
chwpar -N interface=en1 address=10.30.194.131 netmask=255.255.255.0 aix53
chwpar -N interface=en1 address=10.30.194.132 netmask=255.255.255.0 aix53

You can do so for multiple addresses, including IP aliases into the wpar on the same physical interface/ To map new or migrated disks (by SAN for example), you can use this same chwpar command:

chwpar -D devname=hdisk2 devtype=disk aix53
chwpar -D devname=hdisk3 devtype=disk aix53
chwpar -D devname=hdisk4 devtype=disk aix53

Once the disks are added, login into the wpar using clogin, and pass a cfgmgr in order to load the newly mapped disks. You should then be able to import your Volume Group and or create a new one. Have fun :/
