Is there any command that will give me a summary of system information, such as # of CPUs and speed, Total Memory, # of HDDs and size?

If not is there one that will at least give me proc. speed? (I know the individual commands for memory and hard drive size)

Use dmesg command

Then change directory to /proc

cd /proc
ls -l
Here most of the files has system info like cpuinfo file just cat them

Or try shell script

I was not aware that the 'dmesg' command was available in AIX. I don't think that it is.

nmon gives a lot of useful info.
You may also want to do it my way :
# bindprocessor -q
The available processors are: 0 1 2 3
# lsattr -E -l mem0
goodsize 512 Amount of usable physical memory in Mbytes False
size 512 Total amount of physical memory in Mbytes False
# lsattr -E -l proc0
frequency 374999808 Processor Speed False
smt_enabled false Processor SMT enabled False
smt_threads 0 Processor SMT threads False
state enable Processor state False
type PowerPC_604e Processor type False
# lspv
hdisk0 00439c5bb7a4ec67 rootvg active
hdisk1 00439c5be10d6265 rootvg active

bindprocessor -q shows all available processor. As you can see I also use lsattr and lpv.
lsvg rootvg shows available space, lsdev -Ccdisk shows disk type.

Cool, thanks Zorba. I think I'm going to throw these into a script.

prtconf works well on v5+ ...

That's funny. Two things wrong with that. 'dmesg' doesn't exist in AIX. Neither does 'less'.

And /proc contains none of the information typically found there on a Linux system. At least, it's not as easy to find.

Another quick and dirty way to get the processor speed is:

pmcycles

HTH

lsattr -El sys0

displays quite abit of info - you might try it
