Take the following steps, depending on what SCO operating system
you have installed:
SCO OpenServer5
---------------
Product information on OpenServer5 is available from:
http://www.sco.com/products/openserver6/6_507_chart.pdf
Run the following command to determine how many CPU's the kernel
has recognized:
uname -X
You can obtain more information if you have the "hw" command
installed:
/etc/hw -r cpu
Run the following command to determine if the appropriate
Multiprocessor software is installed and is correctly licensed:
/usr/bin/customquery swconfig | grep -i multi
This should return information on the SCO Symmetrical
Multiprocessing version installed.
/etc/brand -L
SCO symmetrical multiprocessing for OpenServer 5 needs to be
licensed for the number of physical CPUs you have.
This command will tell you how many SMP licenses have been entered
and the type of license used, denoted by the number.
For example, c2 means two CPUs are licensed.
If the SMP software has been installed, you can run this command:
/etc/cpuonoff -c
This will report the state of the processors found.
If a CPU is detected, yet it's state is classed as "inactive" then
check the SMP Licensing is sufficient to cover the additional CPU's
installed.
Installing SMP and it's license will grant you use of an additional
or second CPU. Subsquent CPU's must be licensed separately with
Additional CPU licenses.
Please note that a display problem can cause a discrepency in how
the CPU speed is reported in "hwconfig" and "hw". For example:
hwconfig:
clock - type=TSC/2.999999949Ghz
hw:
CPU 1 performs like a 1129Mhz Intel Pentium III Model 7
This is reported on systems running SMP and is a cosmetic display
issue with "hw".
Further troubleshooting:
Number of licensed CPUs for the operating system (add up the 'c'
numbers):
brand -L | grep "c[0-9]*:" | awk '{print $4}'
Number of active CPUs (physically present, licensed, and running):
echo stat | crash
For SMP Licensing see:
Technical Article 126403, "How do I enable Multi-Core, Dual Core or Hyper-Threading
on OpenServer 5.0.7?"
SCO OpenServer6
---------------
Product information on OpenServer6 is available from:
http://www.sco.com/products/openserver6/6_507_chart.pdf
In addition to introducing the Starter Edition, with OpenServer 6
SCO has revised the default configurations of the Enterprise
Edition to provide more value along with the major new features
contained in this latest release. The following table summarizes
the OpenServer 6 Edition configurations:
Edition Starter Enterprise
Users 2 10
CPUs 1 4
Memory 1GB 4GB
Run the following command to determine how many CPU's the kernel
has recognized:
uname -X
You can obtain more information if you have the "hw" command
installed:
/etc/hw -v
To see the state of the processors detected, use the following
command:
/sbin/psrinfo -v
The more verbose command is:
/sbin/psrinfo -vv
/etc/cpuonoff -c
This will report the state of the processors found.
Please note that in January 2008 SCO announced that you no longer
needed a license for additional CPUs on OpenServer 6.0.0 and
UnixWare 7.1.4. To eliminate the need for additional CPU licenses
on SCO OpenServer 6.0.0 please see:
http://www.sco.com/support/update/download/release.php?rid=319
SCO UnixWare7
-------------
Product information on UnixWare7 is available from:
http://www.sco.com/products/unixware714/SCO_UW714_Broch_final2004.qxd.pdf
Run the following command to determine how many CPUs the kernel
has recognized:
uname -X
You can obtain more information if you have the "hw" command
installed:
/etc/hw -v
Run the following command to determine if the appropriate
Multiprocessor software is installed:
pkginfo | grep osmp
This should return the following:
system osmp OS Multiprocessor Support (OSMP)
To see the state of the processors detected, use the following
command:
/sbin/psrinfo -v
The more verbose command is:
/sbin/psrinfo -vv
Please note that in January 2008 SCO announced that you no longer
needed a license for additional CPUs on OpenServer 6.0.0 and
UnixWare 7.1.4. To eliminate the need for for additional CPU
license on UnixWare 7.1.4 please see:
http://www.sco.com/support/update/download/release.php?rid=337
All Releases:
------------
In addition, ensure that the latest Maintenance Pack is installed,
available from:
http://www.sco.com/support/download.html
Also check your BIOS settings on the server. For example, a common
option for turning off CPU's is disabling the computer's APIC.
Additional licenses can be added either with:
# scoadmin license
or alternatively, using "brand -g -a" and then "sco_pmd -r" to add
it manually.
NOTES:
To see what licensing you already have without having to run
"scoadmin", "scoadmin license" or "scoadmin lic" then either run:
# brand -X
or:
# brand -L
or "uname -X" and "uname -a" will give you plenty of information.
NOTES:
Troubleshooting
---------------
casm (/etc/rc2.d/S20cpacasm) reporting x number of Physical
Processors seen but only 1 available then this is being reported by
HP/Compaq's EFS tools for the Insight Management Agents and is
likely to be a hardware error.
