Virtual Partitions (vPars) Management on nPartitions

Adding or Removing nPartition Cells from a

Virtual Partition

This section describes how you can add cells and remove cells from an

nPartition that is running HP-UX in one or more Virtual Partitions.

See vPar Management of nPartitions: Reconﬁguring nPartition Attributes

from a vPar on page 514 for details on reconﬁguring other nPartition

attributes, such as boot paths or the nPartition name, from a vPar.

Complete nPartition conﬁguration procedures are given in the chapter

Managing nPartitions on page 245.

vPar Management of nPartitions:

Adding and Removing nPartition Cells from a vPar

This procedure covers how to add and remove cells from an nPartition

that is running the HP Virtual Partitions software product.

In this procedure, you make changes to the local nPartition from HP-UX

running in a vPar in the nPartition.

For details on modifying remote nPartitions, or nPartitions not currently

running vPars, refer to the chapter Managing nPartitions on page 245.

NOTE After removing one or more cells from an nPartition, any vPars deﬁned

within the nPartition may need to be reconﬁgured if they explicitly used

processor or I/O resources on the removed cell(s).

The vPars software product automatically adjusts vPar conﬁgurations as

needed to account for any expected hardware that is unavailable; as a

result, the vPars database may automatically be changed after a cell is

made inactive or is removed from its nPartition.

After adding one or more cells to an nPartition, to use the resources on

the new cell(s) you also must modify the nPartition’s Virtual Partition

conﬁgurations. For example, for a vPar to bind the new cell’s processors

or use any attached I/O slots you must add the resource to the vPar by

using the vparmodify command or the Virtual Partition Manager utility.

Likewise, after an nPartition’s inactive cell is made active you also must

modify the nPartition’s Virtual Partition conﬁgurations to explicitly use

the cell’s processor or I/O resources.
