Use the Power On Managed System window to select options for powering on the system.
Choose from the following modes:
Partition standby: Allows you to create and activate logical partitions. When the Partition standby power-on is completed, the system will be in standby mode.
System profile: Powers on the system according to a predefined set of system profiles. Select the system profile that you want to use from the list below.
Partition auto start : Powers on the managed system to partition standby mode and then activates all partitions that are marked as auto start or those partitions that were running when the system shut down. For example, if you create a partition with four processors, dynamically remove one processor from the logical partition, and then shut down the system, the partition auto start option activates this partition with three processors because the three-processor configuration was the last configuration used. The Hardware Management Console (HMC) ignores whatever is specified in the profile for the partition. You can create and activate logical partitions in partition auto start mode.
Hardware Discovery: This option is available only if the system is capable of using the hardware discovery process to capture I/O hardware inventory for the managed system. The hardware discovery process captures information about all I/O devices -- in particular those devices not currently assigned to partitions. When you select the hardware discovery power on option for a managed system, the managed system is powered on into a special mode which performs the hardware discovery. After the Hardware Discovery process is complete, the system will be in Operating state with its partition(s) in power-off state. The Hardware Discovery process records the hardware inventory in a cache on the managed system. The collected information is then available for use when displaying data for I/O devices or when creating a system plan based on the managed system.
Additionally, choose a system profile that contains the partitions that you want to have activated when the managed system is powered on.
