Matrix Operating Environment Getting Started Guide at http://www.hp.com/go/matrixoe/docs.
For added information on using the HP Capacity Advisor Consolidation software license, see “Data

Capacity Advisor Consolidation software licenses cannot be used on the same system at the same
time.
Installation
Capacity Advisor is installed with other Matrix OE components, so no separate installation is
required. (See the Matrix Operating Environment installation guide that is appropriate for your
operating system at http://www.hp.com/go/matrixoe/docs.) To use Capacity Advisor, you must
have a valid license.
Collection methods
On installation of Matrix Operating Environment, the Insight managed system setup wizard
automatically configures the mechanism used to collect data from managed servers based on the
type of operating system that the managed system is running. (See “Supported collection
configurations” (page 18).)
Some problems with data collection can be diagnosed with vseassist. See the HP Matrix
Operating Environment Getting Started Guide for additional information.
