Create Partition - HP AlphaServer ES47 Cli Reference Manual

AlphaServer ES47/ES80/GS1280 Server Management CLI Reference

3.15 create partition

Creates a partition. This command adds a new hard partition by providing the hard partition
name, maximum number of CPUs, subpartition type, and optional modifiers. It creates a
subpartition if the subpartition name is given. No attributes are necessary for a subpartition. (You
use assign component or assign memory to define the components of a partition or subpartition.)
If no hard partitions are defined, a Default_HP and Default_SP are created with all CPUs and IOs
belonging to the Default_SP. The creation of the first user-created hard partition causes the
Default_HP to be deleted. The components of the deleted Default_HP go to the Global
Free_Pool. Whenever a hard partition is created, a Default_SP along with the Free_Pool is
created under that hard partition. When the first user-defined subpartition is created under a hard
partition, the Default_SP is deleted and its components go to the Global Free_Pool.
Syntax
create partition
Arguments
-hp <hard_partition>
-sp <sub_partition>
max_CPUs
sub_partition_type
Options
-stripe Specify memory striping.
Examples
1. Create a hard partition account_dept with a maximum of 8 CPUs, define any
subsequently created subpartitions as soft partitions, and request memory striping.
MBM> create partition –hp account_dept 8 soft -stripe
MBM>
2. Create a subpartition under the hard partition account_dept.
3-24
{{-hp <hard_partition> <max_CPUs>
<sub_partition_type> [-stripe] },
{-hp <hard_partition> –sp <sub_partition>}}
Hard partition name. The name is limited to 19 characters
(alphanumeric and underscore only) and it cannot be
Default_HP or Free_Pool.
Subpartition name. The name is limited to 19 characters
(alphanumeric and underscore only) and it cannot be
Default_SP or Free_Pool.) . A hard partition is created if no
subpartition name is given.
The maximum number of CPUs that can ever be placed in the
hard partition. This value is used to determine the proper routing
and memory algorithm.
The type of subpartitions in this hard partition:
soft soft partitions
firm firm partitions
semi semi-firm partitions
