RAM size

UNIX HP-UX
1

hi,

while i am working in hpux 11.23 using a telnet connection how do i check the RAM size and hard disk size?

'df' or 'df -h' should give you information about mounted disks' capacities. I know that in linux, 'free' will give similar info about ram, so it's worth a try in HP/UX. 'top' should also give RAM info.

HP-UX 11.23 has a new command called /usr/contrib/bin/machinfo. This will give you CPU, MEMORY and serial info.

For disk info, use ioscan -fnkC disk command then diskinfo command will give you info about each disk.

hey Sekar;

MEMORY:
#top - virtual + real
if diagnostics installed
#cstm
cstm>map // lists the i/o's
cstm>sel dev X //memory device number (number on far left)
cstm>map // should see and * next to it
cstm>info
cstm>il // information logs on the memory

DISK:
ioscan -fnC disk - check the special device cXtYdZ
run diskinfo -v /dev/rdsk/cXtYdZ

hope that helps!
Salam

This script uses adb and wont work correctly on Vpars, but in all other cases will work perfectly..
