Creating a New Partition
Use the procedures in this section when creating new partitions using
the available cells within your Superdome complex.
At least one cell in each partition must be connected to an I/O chassis
that has the appropriate PCI cards and devices installed.
When creating a partition, you must adhere to the requirements and
guidelines described in “Partition Configuration Guidelines” on page
125. HP recommends only a specific set of partition configurations.
If no partitions exist on your HP Superdome complex, you must first
establish a “Genesis Partition” before creating other partitions. See
“Creating a Genesis Partition” on page 153.
HP-UX Commands The following procedure uses the parstatus,parcreate, andparmodify
HP-UX commands to create a new partition on a Superdome server.
This procedure uses parstatus to find available (unassigned) cells, uses
parcreate to create a partition using the cells, and uses parmodify to
modify the partition’s settings and configure it for general use.
One alternative to using the following five-step procedure is to replace
steps 2–5 with a single parcreate command.
For example, the commands performed in steps 2–5 could be replaced
with the following parcreate command line.
Note that in the above alternative, the -B option is specified, thus
causing the partition to be booted immediately.
You can perform this task using HP-UX commands or
Partition Manager.
