About This View

This view displays general information and properties of a specific nPartition. It includes a summary of all the powered-on components that belong to the nPartition.

Use this view to examine the configuration of an nPartition. You cannot directly change the contents of any field in this view. To modify the nPartition's properties, select the nPartitionModify action from the actions menu.

General Partition Properties

The General Partition Properties table shows the properties of the nPartition.

Table 1 General Partition Properties

nPartition Name

The partition name that identifies this nPartition. Partition names should be meaningful to the system administrator, but they have no significance to Partition Manager. They are not required to be unique. However, assigning unique partition names will avoid confusion and reduce operator errors. It is strongly recommended that you assign each nPartition a unique partition name.

Status

The current status of the partition. This can be one of the following values.

Active

An nPartition is active if at least one of the cells in the partition is active.

Inactive

An nPartition is inactive only when all of its cells are inactive.

nPartition Number

The partition number that uniquely identifies this nPartition within the complex. Partition numbers are automatically assigned when the nPartition is created, and cannot be changed. The first nPartition in the complex is assigned partition number 0.

Active Core Cell

The cell that is currently serving as the core cell for the nPartition. This field is only defined for active nPartitions. There is no active core cell for inactive nPartitions, since the core cell is not selected until the nPartition is booted.

Cells are identified by their cabinet number and cell slot within the cabinet (e.g. “cab0, cell2”). You can click on the cell identifier to view the cell details. This will take you to the cell scope general view for that cell.

Operating System

If the nPartition is active and has booted an operating system, then the operating system identification string will be shown here. If Partition Manager is unable to obtain this information, this field will display “?” (unknown status).

Host Name

If the nPartition is active, has booted an operating system, and has been assigned a network host name, the host name will be shown here. If Partition Manager is unable to obtain this information, this field will display “?” (unknown status).

Admin IP Address

The network IP address associated with this nPartition. If there is no IP address, this field will contain “-”.

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.

Hardware Status

This field indicates the highest problem status of the hardware components of the nPartition. Refer to status indicators for more information.

Hyper-Threading Enabled

Enabled means that Hyper-Threading will be active on the next reboot of the nPartition.

Regardless of the enabled state, Hyper-Threading might be active for an nPartition. Check the Hyper-Threading Active field to determine whether an nPartition actively is supporting Hyper-Threading.

This information is displayed only for nPartitions whose processors support Hyper-Threading.

Hyper-Threading Active

Active means that each processor core in the nPartition is simultaneously running multiple threads.

This information is displayed only for nPartitions whose processors support Hyper-Threading.

Primary Boot Path

The device path assigned as the primary boot path (PRI) for this nPartition. This identifies the disk device that will be used to boot the operating system.

HA Alternate Boot Path

The device path assigned as the high availability alternate boot path (HAA) for this nPartition. This identifies the disk device that will be used to boot the operating system if the cell to which the PRI disk is connected fails or is otherwise inactive.

Alternate Boot Path

The device path assigned as the alternate boot path (ALT) for this nPartition. This identifies an alternate disk device which can be chosen during the boot disk selection process to boot the operating system.

 

Summary of Components

The Summary of Components table displays the number of each type of hardware resource that is powered-on in the nPartition.

Only powered-on components are counted in this table.

Table 2 Summary of Components

Cells

The number of powered-on cells in the nPartition.

CPUs

The number of powered-on CPUs across all the cells in the nPartition.

DIMMs

The number of powered-on DIMMs across all the cells in the nPartition.

Memory

The total amount of memory (in gigabytes) on all the powered-on DIMMs in the nPartition.

I/O Chassis

The number of powered-on I/O chassis connected to powered-on cells in the nPartition.

I/O Cards

The number of I/O cards installed in powered-on I/O card slots in powered-on I/O chassis connected to powered-on cells in the nPartition.

 

Show / Hide Memory Configuration

Initially, this view does not show the memory configuration of the cells in this nPartition. If you want to see this information, click the button labeled [Show Memory Configuration >>].

The Interleaved Memory Regions table shows how the interleaved memory in the nPartition is configured. This table will not be shown if Partition Manager is unable to obtain that information, and a message will be displayed in its place. Memory interleave occurs when the nPartition is booted, so no interleave information will be available if the nPartition is inactive or has not booted, or if the server and operating system configuration does not provide interleaved memory regions.

Interleaved memory consists of one or more regions across the cells of the nPartition. An optimal interleave can be constructed when the number of cells contributing to the interleave is a power of 2, and every cell contributes the same power of 2 gigabytes of memory (including 0.5GB). In this case, a single interleaved memory region will exist. In other situations, multiple regions will be created. For example, if an nPartition has four cells, two of which have 12 GB of memory and 2 of which have 8 GB of memory, then two interleave regions will be created: one involving all four cells contributing 8 GB each, and one with only two cells contributing 4 GB each.

Table 3 Interleaved Memory Regions

Interleave Region

The regions are numbered sequentially, starting with 0. The region number has no specific significance.

Cell Location

Each cell that contributes to the region is listed here. Cells are identified by their cabinet number and cell slot within the cabinet (e.g. “cab0, cell2”). You can click on any cell identifier to view the cell details. This will take you to the cell scope general view for that cell.

Interleave Amount (GB)

The amount of interleaved memory contributed by each cell in the region, in gigabytes.

Total Region Amount (GB)

The total amount of memory in this interleave region, in gigabytes. This is the sum of the memory contributed by each cell in the region.

 

The Cell Local Memory (CLM) Allocations table shows the allocation of cell local memory (CLM) in the nPartition.

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.

Table 4 Cell Local Memory (CLM) Allocations

Hardware Location

The physical location of the cell (cabinet and cell slot). You can click on the cell identifier to view the cell details. This will take you to the cell scope general view for that cell.

Cell Type

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

Total Memory OK (GB)

The total amount of memory, in gigabytes, configured for use on the cell.

Actual CLM Usage (GB)

The amount of cell memory, in gigabytes, that was allocated as CLM when the nPartition was booted. This column is omitted if the nPartition is inactive. The actual CLM can differ from the requested CLM due to cell hardware constraints and minimum interleaved memory requirements imposed by system firmware.

Requested CLM

The amount of cell memory, in gigabytes, that was requested to be used as cell local memory.

Requested Interleave (GB)

The amount of cell memory, in gigabytes, that was requested to be used as interleaved memory.

Actions

At the right side of each view is a menu of actions that Partition Manager can perform. These actions are grouped into six submenus. To expand a submenu, click on the [+] icon to the left of the submenu name. The actions under that submenu will be shown, and the icon will change to [-]. Click on that icon to collapse the submenu. The actions under the submenu will be hidden, and the icon will change back to [+].

When Partition Manager begins, each submenu is collapsed. When you change views, submenus that you have expanded will remain expanded, and submenus that are collapsed will remain collapsed.

Not all actions appear in the menu in each view. Some actions that do appear in the menu are disabled under certain conditions. Actions that are disabled are dimmed in the menu and cannot be clicked. Actions are enabled or disabled based on the current state of the system and which objects are currently selected.

If you position the mouse cursor over the name of an action without clicking, a pop-up tool tip will appear. If the action is currently enabled, the text will explain what the action does. If the action is currently disabled, the text will explain why it is disabled.

The following table shows the actions that are enabled in this view. Actions that cannot be enabled in this view are not included. To the right of each submenu and action is a brief description, including any requirements for the action to be enabled. If the required conditions are not met, then the action will be dimmed in the menu, and it cannot be selected. Click on an action name to go to the detailed help for that action.
