It's when I see things like this that I think AIX has taken a seriously wrong direction in development.

The page_table size in POWER5 and POWER6 is 1/64 of the max memory size, so you have to calculate that. I dont know of a command to just list it - but I have not searched exhaustively.
This is as close as I can come to your command:
michael@hmc1:~> lshwres -r mem -m p520-1 --level lpar --header -F curr_mem,curr_max_mem,lpar_name
curr_mem,curr_max_mem,lpar_name
640,768,VIO1

Hi,
Is there a command that gives output similar to the p4 command/output:
# lshwres -m <managed system> -r mem
allocated page_table partition assigned_to
12544 256 005*7040-671*
4224 128 007*7040-671*
14848 512 001*7040-671*
8448 256 002*7040-671*
This output tells you exactly how much memory is used for the page tabled per partition, which is very usefull when using dedicated partitions. On the P5 systems I cannot find this info per partition.
