I checked it on AIX 6.1; maybe check the man page for svmon on AIX 5.3 if there is a similar option.
Else use for example awk to calculate MBs.

You could have searched this forum, because the question has been asked (and answered) time and again. Now, for one more time:

total memory:

Code:

lsattr -El mem0

free memory: depends on what you define as "free", because the AIX tries to put every bit of memory to use - either for programs ("computational memory") or as file cache. Therefore, what is reported as "free" (which more to the point means "unusable at this moment") is a meaningless number. You could stop a running program and the free memory wouldn't even change, because the memory being freed is added to the file cache.

For details see here.

I hope this helps.
