  9. 7.9 Setting a CPU Operational Mode for the Physical Partition

7.9 Setting a CPU Operational Mode for the Physical Partition


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.
  1. 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.     
  2. 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. 
XSCF>showpparmode -p 0
Host-ID                :0f010f10
Diagnostic Level       :min
Message Level          :normal
Alive Check            :on

Autoboot(Guest Domain) :on
Elastic Mode           :off
IOreconfigure          :true
CPU Mode               :auto
PPAR DR(Current)       :off
PPAR DR(Next)          :off
  1. To change the CPU mode to "compatible" mode, execute the setpparmode command and set the CPU Mode to "compatible".
XSCF>setpparmode -p 0 -m cpumode=compatible

  1. Execute the showpparmode command, and confirm that the CPU Mode of the physical partition has been set to "compatible".
