Use the Power On task to start a managed system.
Choose from the following options to power on your managed system:
Normal: Select this option to specify that the HMC uses
the current setting for the partition start policy to determine how
to power on the managed system. The current setting can be one of
the following values:
- Auto-Start Always: This option specifies that the HMC
power on logical partitions automatically after the managed system
powers on. If powering on the managed system is the result of a user
action, the HMC starts all partitions that are configured for automatic
start up. If powering on the managed system is the result of an automatic
recovery process, the HMC starts only those logical partitions that
were running at the time the system powered off. This option is always
available for selection.
- Stop at Partition Standby: This option specifies that
logical partition start up is in standby mode after the managed system
powers on and the HMC does not start any logical partitions when the
managed system powers on. If powering on the managed system is the
result of an automatic recovery process and the HMC is used to start
a logical partition, the HMC starts all logical partitions that were
running at the time the system powered off. This option is available
for selection only when the firmware for the managed system does not
support advanced IPL capabilities.
- Auto-Start for Auto-Recovery: This option specifies that
the HMC power on logical partitions automatically only after the managed
system powers on as the result of an automatic recovery process. This
option is available for selection only when the firmware for the managed
system supports this advanced IPL capability.
- User-Initiated: This option specifies that the HMC does
not start any logical partitions when the managed system powers on.
You must start logical partitions manually on the managed system by
using the HMC. This option is available for selection only when the
firmware for the managed system supports this advanced IPL capability.
You can set the partition start policy from the Power On Parameters
page of the Properties task for the managed system.
System profile: Selecting this power-on option specifies
that the HMC power on the system and its logical partitions based
on a predefined system profile. When you select this power-on option,
you must select the partition profile that you want the HMC to use
to activate logical partitions on the managed system.
Hardware Discovery: Selecting this power-on option specifies
that the HMC run the hardware discovery process when the managed system
powers on. 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 any
partitions in the 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. 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.
