By meeting the requirements for using the inventory gathering
process, you can enhance the quality and quantity of data that you
collect in the system plans that you create on the Hardware Management Console (HMC).
To maximize the amount and type of hardware information
that the inventory gathering process is able to collect from the managed
system, ensure that you complete the following tasks before you create
a system plan:
- Ensure that data in the inventory cache on the managed system
is maximized and current. See Tips for maximizing data in a system
plan on the HMC for more information.
- Ensure that the managed system is in the standby state or that
the managed system is powered on.
Note: You cannot create a system
plan if the managed system is in either the power-off state or the
recovery state.
- Ensure that all the logical partitions are activated on the managed
system from which you plan to base the new system plan.
- Ensure that the IBM® Installation
Toolkit for the Linux operating
system is loaded if you are creating a system plan that will have
information about a Linux system
or logical partition running in the Linux environment.
This toolkit is required so that systems and logical partitions that
run in the Linux operating
environment can perform inventory gathering. The IBM Installation Toolkit for the Linux operating system
is available at the IBM Service
and productivity tools website.
- Ensure that you have a Resource Monitoring and Control (RMC) connection
between the HMC and
each logical partition. An RMC connection is required for the inventory-gathering
process. The use of RMC ensures that the inventory gathering process
can capture more detailed hardware information. Without RMC, for example,
the inventory gathering process is not able to detect the types of
disk drives installed on a managed system.
Note: IBM i logical partitions
use Management Central to respond to RMC requests from the HMC. It is possible
for a logical partition to have more than one HMC to manage it. In this
situation, if you want to use RMC to create a system plan, you must
ensure that you create the system plan from the primary HMC that manages the logical
partition because secondary HMCs
cannot use RMC.
To ensure that the
HMC can use RMC, complete
the following steps:
- In the HMC navigation
area, select HMC Management.
- In the contents area, select Change Network Settings.
The Customize Network Settings window appears.
- Click LAN Adapters, select the appropriate
adapter from the list, and click Details.
- On the Basic Settings page of the LAN Adapters Details window,
ensure that Partition communication is selected.
- On the Firewall Settings page, in the Available Applications list,
select all instances of RMC, and click Allow Incoming,
if necessary.
- Click OK to close the LAN Adapter Details
window.
- Click OK to close the Customize Network
Settings window.
- Restart the HMC if
you made any changes to these configuration settings.
For some operating systems, you might need to perform
additional steps to ensure that RMC is configured and running correctly. To learn more about configuring and using RMC, see
the Understanding RMC and resource managers website.
