>What mean switch 2D or 2U, 3U?

I doubt you really want to know the arcane syntax for the old adb. :-(

2D means format 2 32 bit words as signed decimal. U for unsigned.

Hi Slawek:

The 'adb' manpages will help you decipher things a bit. The "2D" specifies two (2) occurances of a D(ecimal) number.

There are better (at more universal) ways of obtaining kernel information, among the various releases, especially as you move to the current releases. Use 'kctune' or 'kmtune'. For physical memory:

On Itanium servers:

# machinfo

On PA-RISC servers:

# echo "selclass qualifier memory;info;wait;infolog"|cstm

Hi,
Some command are very good like
glance -m, or you can use cstm too.
there is a utility in perl, ok first write for solaris named memconf

I want use command adb,if is it possible?

I'd like add that now i have situation

bash-3.2# machinfo | grep '^Memory'
Memory: 1018 MB (0.99 GB)

bash-3.2# echo phys_mem_pages/D | adb -o /stand/vmunix /dev/kmem
phys_mem_pages:
phys_mem_pages: 0

bash-3.2# echo phys_mem_pages/2U | adb -o /stand/vmunix /dev/kmem
phys_mem_pages:
phys_mem_pages: 0 260752

Why phys_mem_pages return value 0?

Thanks for help

adb is the last command you want to use. machinfo(1) works on Integrity.

Hi (again) Slawek:

> How can I check memory on Itanium. I want use command adb,if is it possible?

Why? If you build scripts to use 'adb' you are at the mercy of the kernel architecture and the internals of 'adb' as releases change and/or you try to run on older versus newer operating systems and/or hardware architectures.

Use a supported, standard interface like 'machinfo' on Itanium and parse out the memory information:

# machinfo|grep ^Memory
