2.6.4 Relationship Between the CPU Operational Mode and Physical Partition Dynamic Reconfiguration
This section describes the relationship between the CPU operational mode and the addition or deletion of a SPARC M10-4S through physical partition dynamic reconfiguration.
Relationship between the CPU operational mode and the addition through physical partition dynamic reconfiguration
A system board with the SPARC SPARC64 X+ processor can only be added to a physical partition operating with the SPARC SPARC64 X+ function in SPARC M10 through dynamic reconfiguration.
You cannot dynamically incorporate the SPARC64 X processor, which does not support the SPARC64 X+ function.
If you try to add a system board with the SPARC64 X processor through dynamic reconfiguration, the addition process fails with the following message.
You cannot dynamically incorporate the SPARC64 X processor, which does not support the SPARC64 X+ function.
If you try to add a system board with the SPARC64 X processor through dynamic reconfiguration, the addition process fails with the following message.
The current configuration does not support this operation. |
To a physical partition operating with the SPARC64 X function, you can dynamically add a system board either with the SPARC64 X or SPARC64 X+ processor through dynamic reconfiguration.
Table 2-15 lists the relationship between the physical partition configuration, CPU operation type, and CPU configuration for a system board that can be added through dynamic reconfiguration.
Physical Partition Configuration | CPU Operation Type | Dynamic Reconfiguration for System Board With SPARC64 X+ Processor | Dynamic Reconfiguration for System Board With SPARC64 X Processor |
---|---|---|---|
SPARC64 X+ | Operates with the SPARC64 X+ function | Yes | No |
SPARC64 X+ | Operates in SPARC64 X compatible mode | Yes | Yes |
Mixed use of SPARC64 X+/SPARC64 X | SPARC64 X+ operates in SPARC64 X compatible mode | Yes | Yes |
SPARC64 X | Operates with the SPARC64 X function | Yes | Yes |
Relationship between the CPU operational mode and deletion through physical partition dynamic reconfiguration
When the CPU operates with either the SPARC64 X+ or SPARC64 X function in SPARC M10, the system board can be deleted through dynamic reconfiguration.
Table 2-16 lists the relationships between the physical partition configuration, CPU operation type, and CPU configuration for a system board that can be deleted through dynamic reconfiguration.
Physical Partition Configuration | CPU Operation Type | Dynamic Reconfiguration for System Board With SPARC64 X+ Processor | Dynamic Reconfiguration for System Board With SPARC64 X Processor |
---|---|---|---|
SPARC64 X+ | Operates with the SPARC64 X+ function | Yes | - (*1) |
SPARC64 X+ | Operates in SPARC64 X compatible mode | Yes | - (*1) |
Mixed use of SPARC64 X+/SPARC64 X | Operates in SPARC64 X compatible mode | Yes | Yes (*2) |
SPARC64 X | Operates with the SPARC64 X function | - (*1) |
Yes |
*1 This operation is not available in this configuration. *2 For a physical partition with a mixed configuration incorporating the SPARC64 X+ processor and the SPARC64 X processor, execute the setpparmode command to set the CPU operational mode to "compatible". Suppose that you have a system that is configured only with a system board with the SPARC64 X+ processor, after deleting a system board with the SPARC64 X processor through dynamic reconfiguration and with the CPU operational mode set to "auto". In such cases, if you power off and then back on or reset the physical partition, the CPU is restarted with the SPARC64 X+ function. Then, even if you try to add a system board with the SPARC64 X processor through dynamic reconfiguration, it is not possible to do so because the system is operating with the SPARC64 X+ function. Therefore, if you consider an operation that involves active replacement of a system board of a physical partition with a mixed configuration combining the SPARC64 X+ processor and the SPARC64 X processor, set the CPU operational mode to "compatible". |
