Logical partitions

Logical partitions are the distribution of resources within a single system to make it operate as if it were two or more independent systems.

Note: If the system has logical partitions, the terms: console, alternative console, IPL, SST, DST, load source, alternate load source, power off, power on, panel function, product activity log, service action log, Licensed Internal Code log, and operating system refer to the logical partition that you are servicing (unless otherwise stated in a procedure, Failing Item, or Symbolic FRU).

Failed partition: Failures can be reported from the partition that experienced the problem with a resource. Attempt to service from the failed partition unless otherwise directed.

System Attention Light: For partitions, the system attention light is represented as the partition's State.

Powering off and on

Read and understand the power-off and power-on procedures referenced when a procedure directs you to power on or power off a system or partition.

For information on using the Hardware Management Console (HMC) to power on logical partitions, see Activating a partition profile.
For information on using the HMC to power off logical partitions, see Shutting down i5/OS® logical partitions.

Note:

To perform a main storage dump or platform dump of a partition, you must use the Service Focal Point. For information on using the Service Focal Point to perform a main storage dump or a platform dump, see Performing a platform or main storage dump.
When servicing a logical partition, you must use the service documentation that supports the version and release of the logical partition. See Determining the release level of a logical partition.
