kernel parameters

[Richard Amick]

I am working on a clustered system and noticed the memory requirements are different for each machine. Checking the kernel parameters via kmtune reports all parameters the same; using sysdef reports the parameter nbuf is different. Which is correct?

Hi,

sysdef gives you the correct values since it is checking against the "running" configuration or kernel. kmtune is looking at the system file (e.g. /stand/system) which you should probably check - if they are different then possibly then next kernel gen could result in differences.
Here is what kmtune looks at per the man page:
/usr/conf/master.d/* Master configuration tables for kernel and kernel modules

/stand/system Default HP-UX system description file

/stand/system.d/* Kernel module system description files

Regards,
