Instant Capacity Integration with Virtual
Partitions
Overview
In a virtual partition environment, processors that are not assigned to
any virtual partition are considered inactive (in addition to other classes
of inactive processors). Activations and deactivations of processors are
accomplished by adding and removing dynamic (unbound) processors
to/from a virtual partition.
Unassigned processors can be assigned or deassigned using either the
icod_modify command or the vparmodify command, depending on the
version of vPars being used, the type of adjustment needed, and the level
of logging or reporting desired. For example, assignment via the
vparmodify command does not result in logging of the activation, e-mail
configuration change notification, or transmission of an asset report to
HP.
NOTE Deferred activations and deactivations are not supported in any vPar
environment.
The Instant Capacity B.07.x software interacts with virtual partitions
(vPars) software to varying degrees depending on the version of vPars
that is being used.
For HP-UX 11i v2 systems, the required version of vPars software is
A.04.01 or greater. That version, combined with Instant Capacity, is
referred to as the “integrated virtual partition environment”, since it
allows for the best coordination between Instant Capacity software and
vPars software, making it less likely for a complex to be misconfigured or
out of licensing compliance.
For HP-UX 11i v1 systems, the required version of vPars software is
A.02.03 or greater, but version A.04 is not available for that platform.
When A.02 or A.03 versions of vPars are used (on HP-UX 11i v1), the
combination is referred to as a “compatible virtual partition
