This is step 3 of the create nPartition
wizard. In this step you can set optional attributes
of the cells that will be assigned to the new
nPartition.
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.
Cell Attributes
Default cell attributes have been assigned to the cells that you selected in the
previous step. You can keep these defaults and proceed to the next step by
clicking [Next >]. However, the defaults may not provide optimal performance
for the mix of applications that will be used in your nPartition.
For more information about nPartition configuration requirements and
recommendations, refer to the configuration
guide.
Table 1 Cell Attributes
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.
Default: Yes. |
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.
Each nPartition has one
cell that system firmware
selects as the core cell when the nPartition is booted.
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.
If this nPartition contains more than one cell that is capable of being
the core cell, you can use this field to specify the order in which
candidate cells should be tried. You do not have to specify any core
cell choices. If no choices are specified (i.e. this field is set to
None for each candidate cell), then a core cell
will be chosen automatically.
You can specify up to four choices (1st,
2nd, 3rd, and
4th). You do not have to specify all four
choices, but you may not leave any gaps in the choices that you make.
For example, you can specify only a 1st choice,
or only a 1st and 2nd
choice, but you cannot specify only a 2nd and
4th choice.
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.
Default:
When creating a new nPartition, the first four cells that can be core
cells are assigned Core Cell Choice values
1st through
4th, by order of cell slot number.
When modifying an existing nPartition, this field defaults to
None for newly added cells.

Complete This Step
The buttons at the bottom of the page are used to move through
the steps of the wizard.
- [< 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.
- [Cancel]
Exit this wizard without completing this step or any further
steps. Any information provided so far will be discarded.
- [Help]
Display help on this step of the wizard, using a new browser window.
Messages
When you click the [Next >] button, one of the following messages may be
displayed.
There must be at least one viable core cell (i.e., a cell that is attached
to an I/O chassis that contains a core I/O card) that has the Use On Next
Boot flag set to "Yes". Otherwise, the nPartition cannot be booted.
|
Each nPartition must include at least one cell that can be selected at boot
time as the core cell. None of the viable core cells
selected for this nPartition will be active the next time that the
nPartition is booted.
Click the [OK] button to return to the
set cell attributes page. You must set the Use On
Next Boot flag of at least one of the viable core cells to
“Yes”. See the core cell glossary definition for more
information.
|
All of the core cell choices are set to "None". System firmware will
select the core cell (at nPartition boot time) based on its default
algorithm. Click [OK] to continue.
|
You do not have to specify any core cell choices. Click [OK] to
continue on, and a core cell will be selected automatically when the
nPartition is booted. If you want to specify core cell choices, click
[Cancel] instead.
|
There is a discontinuity in the core cell choices. All specified core
cell choices must be in consecutive order before continuing.
|
You do not have to specify all four core cell choices, but you may not leave
any gaps in the choices that you make. For example, you can specify only a
1st choice, or only a
1st and
2nd choice, but you cannot specify only a
2nd and
4th choice.
