By meeting the requirements for using the hardware discovery
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 use the hardware discovery capability when you create a system
plan, ensure that you complete the following tasks:
- Ensure that a minimum of 0.5 processor is available.
- Ensure that a minimum of 256 MB of free memory is available.
Note: If
you do not have the minimum processor or memory available, you can
meet these requirements either by shutting down one or more logical
partitions or by adjusting dynamic processor and memory settings for
one or more logical partitions.
- Ensure that all logical partitions on the managed system for which
you want to use the hardware discovery process are inactive to maximize
the information that the hardware discovery process can capture.
If a logical partition is active, the hardware discovery process cannot
capture new information from the logical partition and instead retrieves
information about the hardware assigned to the inactive logical partition
from the hardware inventory cache on the managed system.
Note: Hardware
discovery does not require the use of Resource Monitoring and Control
(RMC).
- Ensure that the Power off the system after all the
logical partitions are powered off attribute for the
managed system is not selected. The hardware discovery process starts
partitions and powers off partitions to gather information. If the
hardware discovery process powers off the only running partition on
the system, the managed system powers off and system plan creation
fails. To verify the setting for this system attribute, complete these
steps:
- In the HMC navigation
area, select .
- In the Tasks area, click Properties. The
Properties window for the selected managed system opens.
- On the General tab, verify that the Power
off the system after all the logical partitions are powered off attribute
is not selected, and click OK.
