Appendix G. Power On the System
You can power on the pSeries 690 by using HMC or by using the power button on the media subsystem

For more information about using the HMC, refer to the IBM Hardware Management Console for pSeries
Installation and Operations Guide.
HMC Power-On
To power on the managed system, you must be a member of one of the following roles:
v System Administrator

To use the HMC to power on the managed system, do the following:
1. In the Navigation area, click the Partition Management icon.
2. In the Contents area, select the managed system.

The partition standby power-on option allows you to create and activate logical partitions. When the
partition standby power-on is completed, the operator panel on the managed system displays LPAR...,

Note: The full system partition is listed as Not Available because the managed system was powered on
using the partition standby option.
