Process for Selecting Cells for nPartitions
The following steps provide a basic procedure for selecting which cells to
assign to the nPartitions you will create in an HP server.
Step 1. Determine the sizes of all partitions you will create in the server
complex.
Before creating any partitions, determine how many partitions you plan
to configure and establish each partition’s size (the number of cells).
Step 2. Select the largest undefined partition.
If you will configure multiple partitions in the complex, assign cells to
the largest partition first and then configure next largest, and so on, and
configure the smallest partition last.
Step 3. Choose which cells you will assign to the nPartition by using the
partition configuration chart for the server model on which you are
configuring the partitions.
These charts list which cell slots HP supports for assigning to partitions,
based on the partition size and server model.
For partition sizes for which HP recommends multiple configurations,
select the first available set of cells. For example, for a two-cell partition
select configuration 2A, if possible, before selecting 2B or 2C.
Step 4. Confirm that the cells you have selected are eligible to be assigned to the
partition.
For the cells to be eligible, they must meet these requirements:
• The cells must not be assigned to another partition.
• The cells must meet the partition hardware requirements (the
required processor, firmware, and memory configurations).
• The cells should be present (installed) in the server and powered on.
You can assign cells that are not present or on when using
parcreate or parmodify. However, you should install and power on
cells before assigning them to nPartitions in order to allow commands
to automatically check the cells’ compatibility with any other cells in
the partition. Also note that assigning a cell that is not present or on
