This is step 6 of the create nPartition wizard. In this step you will be shown a summary of all of the attributes of the nPartition, allowing you to confirm that it has been correctly defined.

You cannot directly modify any of the fields on the summary page. To make changes to the nPartition configuration before creating it, you must click the [< Back] button and change your entries in the previous steps of the wizard. After the nPartition has been created, it can be modified by selecting the nPartitionModify action.

For an overview of the entire create nPartition wizard, refer to the parent help topic, create nPartition. For a guide to nPartition configuration requirements and recommendations, refer to the configuration guide.

General Tab

This tab displays the high level summary of the nPartition configuration. The following fields are shown.

Table 1 Fields Shown in the General Tab

Complex Name

The name of the complex on which the nPartition is being created.

nPartition Name

The partition name that you assigned at the start of this wizard.

See:  set nPartition name.

Cells

The total number of cells assigned to the nPartition.

See:  select cells.

I/O Chassis

The total number of I/O chassis connected to the cells assigned to the nPartition.

See:  select cells.

CPU Architecture

Identifies the processor family of the CPUs. For PA-RISC systems, this field will show “PA-RISC”. For Itanium®-based systems, this field will show “Itanium(R)-based”.

Cell Compatibility

A string that identifies a hardware class of cells. Cells with the same compatibility code can be assigned to the same nPartition. Cells with different compatibility codes cannot be assigned to the same nPartition. An empty cell slot is considered compatible with any cell or other cell slot.

Firmware Revision

The revision level associated with the system firmware on the cell board.

Boot to System FW UI

Whether the nPartition should be booted as soon as it is created, or should be manually booted later. This will be shown as one of the following values.

Yes The nPartition will be automatically booted to the system firmware user interface after it is created.

ManualThe nPartition will be manually booted later.

See:  set boot options.

 

High Availability Warnings

When this page is displayed, Partition Manager performs a set of high availability checks. If any of these checks produce warnings, a note will be shown on the bottom of the page. To view the details of the warnings, select the HA Checks tab.

Cells Tab

This tab displays the attributes of the cells assigned to the nPartition. The following fields are shown.

Table 2 Fields Shown in the Cells Tab

Hardware Location

The physical location of the cell (cabinet and cell slot). To examine the details of this cell, you can click on the value in this field. A new browser window will display the cell properties view. This shows the same information as the cell scope views. Inside this new browser window, you can switch between the General, CPUs and Memory, and I/O tabs, but you cannot navigate outside the cell scope. Close the new browser window when you have finished examining the cell properties.

Connected To

The I/O chassis, if any, to which this cell is attached. To examine the details of this I/O chassis, you can click on the value in this field. A new browser window will display the I/O chassis properties view. This shows the same information as the I/O chassis scope views. Inside this new browser window, you can switch between the General and I/O tabs, but you cannot navigate outside the I/O chassis scope. Close the new browser window when you have finished examining the I/O chassis properties.

Can Be Core Cell

Whether the cell has the properties required to be a core cell (Yes or No). If the value is No, then no core cell choice value can be specified for this cell.

Cell Type

Always set to Base. Other cell types may be introduced in future releases.

Use On Next Boot

Set this field to “No” to prevent the cell being made active the next time that the nPartition is booted.

Failure Usage

Specifies how the cell will be used after a hardware failure. This is always set to Base. Other failure usage types may be introduced in future releases.

Core Cell Choice

Specifies the preferred order in which cells should be tried as the core cell.

When the nPartition is booted, system firmware will try to select the first choice as the core cell. If that cell is ineligible to be the core cell (for example, if its Use On Next Boot flag is set to No, or a hardware error has occurred), then the second choice will be tried, and so on. If a core cell has not been selected after all of the specified choices have been tried, then system firmware will try other cells in the nPartition. Note that a cell can still be selected as the core cell, even if it does not have a Core Cell Choice value.

 

CPU and Memory Tab

This tab displays information about the CPUs and memory for each cell in the nPartition. This information is presented in three tables. The two summary tables at the top of the page show totals for the whole nPartition.

Table 3 CPUs Summary Table

[active/ok status icon]OK

The total number of CPUs that are configured for use, across all the cells of the nPartition.

[deconfigured status icon]Deconfigured

The total number of CPUs that are installed but deconfigured, and therefore not available for use, across all the cells of the nPartition.

 Max

The total number of CPUs that can be installed in the cells of this nPartition.

 

Table 4 Memory Summary Table

  DIMMsAmount (GB)
[active/ok status icon]OK

The total number of DIMMs that are configured for use, across all the cells of the nPartition.

The total amount of memory, in gigabytes, on the configured DIMMs.

[deconfigured status icon]Deconfigured

The total number of DIMMs that are installed but deconfigured, and therefore not available for use, across all the cells of the nPartition.

The total amount of memory, in gigabytes, on the deconfigured DIMMs.

[failed status icon]Failed

The total number of DIMMs that are installed, but have failed power-on self-test, and therefore are not available for use, across all the cells of the nPartition.

The total amount of memory, in gigabytes, on the failed DIMMs.

 Max

The total number of DIMMs that can be installed on the cells of this nPartition.

(The total amount of memory that can be installed on the cells of this nPartition depends on the currently available DIMM sizes.)

 

The table of cells at the bottom of the page shows the totals for each cell.

Table 5 Cell CPU and Memory Table

Hardware Location

The physical location of the cell (cabinet and cell slot). To examine the details of this cell, you can click on the value in this field. A new browser window will display the cell properties view. This shows the same information as the cell scope views. Inside this new browser window, you can switch between the General, CPUs and Memory, and I/O tabs, but you cannot navigate outside the cell scope. Close the new browser window when you have finished examining the cell properties.

CPU
OK/Deconfig/Max

The CPUs on the specified cell. This is shown as three values, separated by "/":

OK:  The number of CPUs that are configured for use.

Deconfig:  The number of CPUs that are installed but deconfigured.

Max:  The total number of CPUs that can be installed on the cell.

DIMM
OK/Deconfig/Max

The DIMMs on the specified cell. This is divided into the same three categories shown for CPUs.

Memory(GB)
OK/Deconfig

The amount of memory, in gigabytes, on the specified cell. This is shown as two values, separated by "/":

OK:  The amount of memory configured for use.

Deconfig:  The amount of memory that is installed but deconfigured.

CLM Amount (GB)

The amount of cell local memory, in gigabytes, configured on the cell. The remaining memory will be configured as interleaved memory. Cell local memory is only supported on nPartitions running HP-UX 11i v2 (B.11.23), SuSE Linux Enterprise Server 9, or Microsoft® Windows®. If an nPartition is booted under an operating system that does not support CLM, any memory allocated as CLM will be unusable.

 

I/O Chassis Tab

This tab displays information about the I/O chassis connected to the cells assigned to the nPartition.

Table 6 Fields Shown in the I/O Chassis Tab

Hardware Location

The physical location of the I/O chassis (cabinet, I/O bay, and chassis slot). To examine the details of this I/O chassis, you can click on the value in this field. A new browser window will display the I/O chassis properties view. This shows the same information as the I/O chassis scope views. Inside this new browser window, you can switch between the General and I/O tabs, but you cannot navigate outside the I/O chassis scope. Close the new browser window when you have finished examining the I/O chassis properties.

Connected To

The cell to which this I/O chassis is attached. To examine the details of this cell, you can click on the value in this field. A new browser window will display the cell properties view. This shows the same information as the cell scope views. Inside this new browser window, you can switch between the General, CPUs and Memory, and I/O tabs, but you cannot navigate outside the cell scope. Close the new browser window when you have finished examining the cell properties.

I/O Slots
Full/Empty

The number of PCI or PCI-X I/O slots in this I/O chassis. This is shown as two values, separated by "/":

Full:  The number of slots that contain an I/O card.

Empty:  The number of slots that do not contain any I/O card.

Contains Core I/O

Whether this I/O chassis has core I/O (Yes or No). On servers based on the HP sx2000 chipset, core I/O is provided on each cell, so every cell is a viable core cell. On all other nPartition servers, a cell is a viable core cell only if it is attached to an I/O chassis with core I/O.

 

HA Checks Tab

This tab displays the results of the high availability checks (HA checks) performed by Partition Manager. The results are summarized at the top of the page, followed by the results of the individual checks.

The purpose of the high availability checks is to ensure that if some part of the nPartition fails (such as a processor or a DIMM), the nPartition has adequate resources to continue running. In some cases, high availability may not be a concern (for example, if this nPartition will only be used for non-critical applications, or for experimental or transient purposes).

If high availability is not a concern, you may ignore any warnings displayed on this page, and create the nPartition using the current configuration. However, if high availability is a concern, you should reconfigure the nPartition to eliminate HA warnings. Use the [< Back] button to change the selections made in earlier steps of this wizard.

High availability checks can only be performed on cells that are powered on.

List of Individual HA Checks

  • The DIMM configuration of each cell should include a multiple of two echelons per cell. This provides a performance improvement by doubling the cell's memory bandwidth (compared to having only one echelon installed). This is required for high availability; if one echelon fails, the cell still has at least one functional echelon of memory.

  • At least two cells in the nPartition should be capable of being selected as the core cell. This allows the nPartition to boot even if the preferred core cell fails.

    Some server configurations do not provide enough core-capable cells to satisfy this recommendation.

  • All cells should have at least two CPUs. This allows the cell to be active even if one of the CPUs fails.

Complete This Step

The buttons at the bottom of the page are used to move through the steps of the wizard.

Avoid using your browser's “Back” and “Forward” buttons in Partition Manager (except in the online help). When you use these buttons, Partition Manager cannot tell that you have changed to a different view. This can cause problems, including incorrectly displaying which objects are selected in the current view. Instead, use the links and navigation buttons provided by Partition Manager.

If you do use your browser's “Back” or “Forward” buttons, you can refresh the displayed data by clicking the Partition Manager [Refresh] button at the top right of the window, or by selecting the ToolsRefresh Data action from the actions menu.

[< Back]

Go back to the previous step. You can keep clicking [< Back] until you return to the start of the wizard, or resume from any previous step. Once you go back to a previous step, any steps ahead of that will need to be completed again, in the proper sequence.

[Next >]

Accept the information provided in this step, and proceed to the next step. From there, you can use the [< Back] button to return to this step, if you decide to change the information entered here.
