IBM SY44-5902-05 manual Full paging

Attention: For systems with multiple logical partitions, performing an IPL on the primary partition causes the secondary partitions to be powered down. Failing to power down these secondary partitions will cause an abnormal power-down on the secondary partitions and possible loss of data.

The following options are available in the limited paging environment for all operating systems:

vPerform an IPL

vInstall the operating system

vWork with Licensed Internal Code

vWork with disk units

vWork with DST environment

vStart a service tool

vWork with remote service support

vWork with system partitions

vWork with system capacity

vWork with system security

Note: The following options are operating system-dependent. For a list of the options available for your IBM® operating system, see “DST in OS/400 limited paging environment” on page 282.

vPerform automatic installation of the operating system

vSave Licensed Internal Code

vSelect DST console mode

vWork with save storage and restore storage

For a description of each option, see “DST options” on page 10.

Attention: For systems with logical partitions, performing an IPL on the primary partition causes the secondary partitions to be powered down. Failing to power down these secondary partitions will cause an abnormal power down on the secondary partitions and possible loss of data.

Full paging

The full paging environment is used during normal system operation. The DST options vary depending on the release level of the operating system. You remain in this environment when you perform one of the following:

vFunction 21 on the control panel or “Work with Partition Status” screen to access DST (see “Accessing Dedicated Service Tools” on page 4)

This is available only from the primary partition.

vSystem Request key procedure (see “Accessing Dedicated Service Tools” on page 4)

vAccess system service tools (SST) on a system that uses OS/400® (see “Accessing system service tools” on page 282)

All disk units, the Licensed Internal Code, and the operating system are available.

Attention: For systems with logical partitions, performing an IPL on the primary partition causes the secondary partitions to be powered down. Failing to power down these secondary partitions will cause an abnormal power-down on the secondary partitions and possible loss of data.
