WARNING: No such device, tunable, or cdio dmp.

WARNING: No such device, tunable, or cdio dmp.

I'm build a new kernel on several HP-UX 11i servers, that are suppose to be identical.

With the following commands
cd /stand/build
#
# create /stand/build/system file from the running kernel
/usr/lbin/sysadm/system_prep -v -s system
#
# update Kernel parameter in the build/sytem file
/usr/sbin/kmtune -q semmnu -S /stand/build/system
/usr/sbin/kmtune -s semmnu=1400 -S /stand/build/system
/usr/sbin/kmtune -q semmnu -S /stand/build/system
# build new kernel
/usr/sbin/mk_kernel -s /stand/build/system
#
# prep for rebooting new kernel
/usr/sbin/kmupdate
#

On some servers the mk_kernel command issues the following warning:
WARNING: No such device, tunable, or cdio dmp

echo $? = 0 and the kernel gets built.

The systems that don't receive the Warning don't have a dmp entry in /system.

So I wondering:

What is the dmp /system entry for and does the system need it?

Since I generated the system file from the running kernel, why is dmp invalid now?

Your time & assistance is appredicated.

Re: WARNING: No such device, tunable, or cdio dmp.

The dmp may be from the veristas volume manager. It is the dynamic multipathing driver. Do you have different installations of VxVM or did you remove any veritas filesets?
