How to check Memory size in HP-UX

#ioscan -fnC processor

#uname -a

#dmesg | grep -i physical

#swapinfo -t

# machinfo | grep -i memory


How to check Memory size in HP-UX

In HP-UX you can use check physical memory allocated to server from command line as well as from SAM.I am going to describe here how to check memory on HP-UX from command line:
1.) Checking phyiscal memory in HP-UX using dmesg : 

You can check memory in HP-UX using dmesg output. In HP-UX dmesg print HP-UX server messages and hardware information available to system during the boot time.Here is the command to check physical memory in HP-UX using dmesg output :
hp-uxdev# dmesg |grep Physical
Physical: 8388608 Kbytes, lockable: 5614168 Kbytes, available: 6461644 Kbytes
In dmesg output memory is listed as 8388608 Kbytes or 8 GB.Note: in grep use P(upper) case in word physical to get memory information or “grep –i physical”

2.) Checking HP-UX memory using print_manifest :

HP-UX provides very useful command called print_manifest,i am going to use print_manifest to check how much memory is available :
hp-uxdev# print_manifest |grep –i memory
Main Memory: 8192 MB
Print_manifest is very handy command I don’t even have to 

3.) Checking HP-UX memory using cstm:
Check on your HP-UX server if you have cstm installed by running which cstm .If you have CSTM install on your HP-UX server , you can check Physical memory by running following command :
hp-uxdev# which cstm

hp-uxdev# /usr/sbin/cstm

hp-uxdev# print_manifest |grep -i memory
