Full Discussion: CPU Processor ID
Operating Systems AIX CPU Processor ID Post 81687 by bakunin on Tuesday 23rd of August 2005 08:28:10 AM

I don't know what you mean by "processor ID", please clarify.

In case you want to change the output of "lsattr -El proc0": The information comes from the ODM (probably the tables CuAt and PdDv, maybe others too), so it should in principle be possible to change them to some arbitrary values with a finite amount of "odmput ...."-statements. (man odmput)

Even if that is possible (i have never tried it) you might end up ruining the installation and having to reinstall the machine. It might also be, that every time you run cfgmgr the values are being "corrected" to their original values because cfgmgr does exactly this: store information about devices into the ODM.

nstrsched

NSTRSCHED(5)							File Formats Manual						      NSTRSCHED(5)

NAME

       NSTRSCHED - number of STREAMS scheduler daemons to run

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
DESCRIPTION

       This  tunable  defines  the  number  of multiprocessor (MP) STREAMS scheduler daemons to run on systems containing more than one processor.
       Note that uniprocessor (UP) systems do not use an MP scheduler daemon, but both MP and UP systems always  have  one  UP	STREAMS  scheduler
       (supsched).

       If  the	tunable  value is set to zero, the system determines how many daemons to run, based on the number of processors in the system.	If
       the tunable value is set to a positive, non-zero value, that is the number of smpsched daemons that will be created on an MP system.

       Note: This tunable is for use by specific HP products only.  It may be removed in future HP-UX releases.

   Who Is Expected to Change This Tunable?
       Any customer.

   Restrictions on Changing
       Changes to this tunable take effect at next reboot.

   When Should the Value of This Tunable Be Raised?
       This tunable is for use by specific HP products only.  It may be removed in future HP-UX releases.

   What Are the Side Effects of Raising the Value of This Tunable?
       It could change the system performance unpredictably.

   When Should the Value of This Tunable Be Lowered?
       This tunable is for use by specific HP products only.  It may be removed in future HP-UX releases.

   What Are the Side Effects of Lowering the Value of This Tunable?
       It could change the system performance unpredictably.

   What Other Tunable Should Be Changed at the Same Time as This One?
       None.

WARNINGS

       This tunable is for use by specific HP products only.

       All HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases	of
       HP-UX.

       Installation  of  optional  kernel  software, from HP or other vendors, may cause changes to tunable parameter values.  After installation,
       some tunable parameters may no longer be at the default or recommended values.  For information about the effects of installation  on  tun-
       able  values,  consult  the documentation for the kernel software being installed.  For information about optional kernel software that was
       factory installed on your system, see at
