Memory question

Jeffrey F. Goldsmith — Wed, 08 Nov 2006 14:34:02 GMT

I have an L2000 server with HP-UX 11.0 and would like to know if there is a way to check how much memory is installed in the server.
Also, how do I change the size of the swap size to match the amount of installed RAM?

Use cstm to find out the total memory on your system, it'll also show you a complete picture of your memory layout as well.

# echo 'scl q memory;if;wait;il;done' | cstm

~hope it helps

Hi Jeff:

To ascertain what memory you have:

# echo "selclass qualifier memory;info;wait;infolog"|cstm > /tmp/meminfo

To increase your swap space (by example):

# lvcreate -C y -r n -L 8192 -n lvolX /dev/vgNN
# swapon -p 0 /dev/vgNN/lvolX

Then, add the following to '/etc/fstab':

/dev/vgNN/lvolX ... swap pri=0 0 0

No reboot is necessary.

Regards!

1. You can use sam. Go to Performance Monitors=>System Properties.
2. You can create another lvol and make it your primary swap. do a man on swapon

Shalom Jeffery,

cstm is the best tool because it and I think mstm can show you simm/dimm slots and size of memory chips.

xstm for the gui enabled minds does the same thing.

swapinfo -tam

displays swap.

I do swap changes so seldomly I still rely on sam for that. A boot is required for changes to take effect.

Hi ,

You can try dmesg too i think.

The last part of dmesg gives a memory report.
