Properties of Cells
Cells in an HP nPartition server have various properties that determine
how the cells can be used and managed.
The cell properties discussed here include: Assigned and Unassigned
Cells, Base Cells, Core Cells, and Active and Inactive Cells.
To list details about all cells in a server complex you can use the
parstatus -C command. The command output includes the current
partition assignments, usage, and I/O details for the cells.
Assigned and
Unassigned Cells
Each cell in an nPartition server complex either is assigned to one of the
partitions in the complex, or it is unassigned and thus is not used by any
of the partitions. If an I/O chassis is attached to an unassigned cell then
the chassis likewise is not assigned to a partition.
Cells that are unassigned are considered to be available resources; they
are on the server complex’s “free cell list” and are free to be assigned to
any of the existing partitions, or can be used to create new partitions.
Base Cells For the HP-UX 11i release all cells within a partition are base cells.
When you create partitions and assign cells to partitions using
HP-UX 11i utilities, you specify that the cells are base cells. The default
cell type is base cell, so when you use utilities and do not explicitly
specify a cell type the cell will be of type base. If in the future other cell
types are supported then the utilities will allow you to specify the cell
type.
