Measurement Software on iCOD Systems
iCOD systems inherently have fewer active processors than the total
number of processors in the system. This fundamental difference
between the number of active processors and the total number of
processors can cause some processor measurement products and utilities
to report incorrect information. Additionally, when a processor is
dynamically activated, some software products must recognize the
change in the number of active processors in order to report correct
processor related information.
The iCOD system behavior described above along with the associated
system call changes described in the previous section (“iCOD and pstat,
pstat_getdynamic, and mpctl System Calls” on page 128) requires close
examination of and possible changes to measurement related software to
ensure they work properly on iCOD systems. Some non-measurement
applications may also be impacted.
HP’s OpenView measurement software and some HP-UX commands
were modified to work properly on iCOD systems. For example, the
HP-UX commands top and sar were modified in order to report correct
information on iCOD systems.
OpenView Measurement Products
OpenView measurement products, such as MeasureWare and
GlancePlus, must be version C.02.60 or later to provide correct processor
measurements. OpenView measurement products, version C.02.60 or
later, behave correctly on iCOD systems. Earlier versions of the
OpenView measurement products do not work correctly on iCOD
systems.
On Superdome
Systems
On Superdome systems HP recommends updating to the GlancePlus Pak
version C.03.20 or later.
Other Measurement Software
Please check with your measurement software vendor to ensure their
software works properly on iCOD systems and update the measurement
software versions as needed.
