Very Computer

I've inherited an ancient RS6000 box running AIX 3.2.  I was wondering
if anyone knows a command or script to determine the amount of
physical (real) memory installed?

Thanks

1.  bootinfo -r
2.  lsdev -Ccmemory
3.  lsattr -Elmem0

       # lsattr -El mem0

Will give you amout of physical memory . This works on AIX 4.3.0 , and I
hope this
will work on 3.2 also.

       # lsattr -El mem0

You might try using "bootinfo -r" instead

Let's try them on a 3.2.5 system with 128(128x1024x1024)MB installed.
1) use vmstat:  

   vmstat
procs    memory             page              faults        cpu
----- ----------- ------------------------ ------------ -----------
 r  b   avm   fre  re  pi  po  fr   sr  cy  in   sy  cs us sy id wa
 0  0 16241 13348   0   0   0   0    1   0 246  221 117  4  8 88  0

I don't know how to get from that to the right answer.

2) use lsattr -El mem0

   lsattr -El mem0
size   32   Size in Mbytes False
type   0xb  Simm type      False
cardec 0x20 Card type      False

This gives, as noted by others the amount of memory on one card.
You could, of course, do a for loop and add them up.

for i in 0 1 2 3 4 5 6 7
do
lsattr.... this is more work than you should need to do.

3) use bootinfo -r
   bootinfo -r
ksh: bootinfo: permission denied

You need to be root for that on.    

   sudo bootinfo -r
Password:
131072

works perfectly if you are, though.
Gives exactly what you want to know, and nothing extraneous.

No one has (yet) suggested the right answer, which works for
all users at all levels of AIX 3 or 4.

   lsattr -E -l sys0 -a realmem
realmem 131072 N/A False

That's probably because both the command and the response
are UGLY.  I clean them up a little with a "memsize" script.

   memsize
131072K bytes

   cat memsize
/usr/sbin/lsattr -l sys0 -E | awk ' /realmem/ { print $2 "K bytes" }'

PS. Or you can start monitor and see it there.
