Setting A Cpu Operational Mode For The Physical Partition - Fujitsu M10 Installation Manual

7.9 Setting a CPU Operational Mode for
the Physical Partition
This section describes how to set a CPU operational mode for the physical partition.
You can use the setpparmode command of the XSCF to set a CPU operational mode
for each physical partition.
There are two CPU operational modes (cpumode) that are specifiable for the
setpparmode command: auto mode and compatible mode.
The CPU operational mode is set to "auto" mode by default.
auto mode:
■
Enables the database speed-up instructions, which are expanded functions of the
SPARC64 X+ processor.
However, if the SPARC64 X+ processors and SPARC64 X processors are mixed,
the SPARC64 X+ processors are operated compatibly with the SPARC64 X
processor. To perform maintenance by using dynamic reconfiguration in a mixed
configuration, specify compatible mode.
compatible mode:
■
Operates the SPARC64 X+ processor compatibly with the SPARC64 X processor.
To configure a physical partition in which SPARC64 X+ processors and SPARC64
X processors are mixed, specify this mode.
Note - For XCP firmware versions and Oracle Solaris versions that support this function, see
the Fujitsu M10/SPARC M10 Systems Product Notes for the latest XCP version (XCP 2210 or
later) for your server.
1.
Execute the showpparmode command to check the CPU Mode of the physical
partition.
"auto" mode is set as the factory default. In this mode it is automatically
determined if the operation is performed in extended mode or compatible mode.
