in the DEPENDENCIES section are satisfied.
-X mode Specifies the mode for configuring the memory of the cell as Cell Local Memory and
Interleaved Memory. The valid values for mode are:
LORA The memory of the cell is configured as a mix of Cell Local Memory and
Interleaved Memory. The exact mix and layout is determined by the
-Z
option. This is the default.
SMP All of the cell’s memory is configured as Interleaved Memory (no clm).
-x Specifies the resulting parcreate
or parmodify command to be executed.
Note: If
-x option is not specified, by default the
parconfig command displays
the
parcreate or parmodify command on the standard output. You can cap-
ture the command displayed on standard output, edit the command if needed and
explicitly execute it.
-Z policy Specifies the policy for determining type of the cell. This option should only be used
in combination with -X option and mode value as
LORA. The valid values for policy
are:
balanced 75% of the cells are assigned base and remaining 25% of
the cells are assigned float as the cell type. This is the
default.
high_performance All the cells are assigned base as the cell type.
low_cost 25% of the cells are assigned base and remaining 75% of
cells are assigned float as the cell type.
A base cell in the partition participates in Interleaved Memory. 87.5% (7/8) of the
base cell’s memory is used as CLM.
A float cell in the partition does not participate in interleaved memory. All of the
float cell’s memory is used as CLM.
Mapping of Global Cell Numbers to Local Cell Numbers
The cabinets in a complex are numbered starting from 0. The cell slots in each cabinet are also numbered
starting from 0. Each cabinet can have a maximum of 8 cells.
For example, the cells located in cabinet 0 will have the following cell numbers in global format: 0, 1, 2, 3,
4, 5, 6, 7. The cell numbers in corresponding local format will be 0/0, 0/1, 0/2, 0/3, 0/4, 0/5, 0/6, 0/7.
Similarly the cells located in cabinet 1 will have the following cell numbers in global format: 8, 9, 10, 11,
12, 13, 14, 15. The cell numbers in corresponding local format will be 1/0, 1/1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7.
From the above convention the cell located in cabinet 1, slot 0 is identified in the local format as 1/0 or in
the global format as 8. The
parstatus command displays the above cell as "cab1,cell0". The cell
located in cabinet 1, slot 4 is identified in the local format as 1/4 or in the global format as 12. The
par-
status command displays the above cell as "cab1,cell4". See parstatus (1).
RETURN VALUE
The
parconfig command exits with one of the following values:
0 Successful completion.
1 Error condition occurred.
EXAMPLES
Get a recommended configuration for the new local nPartition. Cells of the new partition should be
base
cells with no CLM. A cell located in cabinet 0, slot 0 is a core capable cell and should be included in the
new partition. The partition should have at least 8 CPUs (excluding CPUs attached to the cells specified
through the -c option).
parconfig -O HPUX_11iV3 -X SMP -c 0:base:y:ri -n mincpus:8
Cell located in cabinet 0, slot 1 is free and has 8 CPUs, the output of the parconfig command will be:
parcreate -c 0:base:y:ri:0% -c 1:base:::0%
Get a recommended configuration for existing local nPartition. An existing partition 0 has to be modified.
A cell is located in cabinet 0, slot 1 and belongs to partition 0, has to be retained back in the recom-
mended configuration of the partition with celltype as floating. Another cell is located in cabinet 0,
slot 6 belongs to partition 0 with just 1 CPU. There should be 5 cells (except the one specified through -c
