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
nPartition Modify
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.
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.
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.
