IBM VERSION 5 SY44-5902-05 - Manual (Page 17)

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:
v Perform an IPL
v Install the operating system
v Work with Licensed Internal Code
v Work with disk units
v Work with DST environment
v Start a service tool
v Work with remote service support
v Work with system partitions
v Work with system capacity
v Work 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.
v Perform automatic installation of the operating system
v Save Licensed Internal Code
v Select DST console mode
v Work 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:
v Function 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.
v System Request key procedure (see “Accessing Dedicated Service Tools” on
page 4)
v Access 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.
