Starting A Service Tool; Ipl Type, Mode, And Speed Options; Printing The System Configuration List And Details Of The System Bus, Main Storage, Or Processor - IBM Power System POWER7 Series Common Service Procedures

Starting a service tool

Use this procedure to start a service tool.
Select this option from the Use Dedicated Service (DST) Tools display.
Note: The Start a service tool option is also available from the System Service Tools (SST) display.
The following options are available from the Start a Service Tool display:
v Display/alter dump
v Licensed Internal Code log
v Licensed Internal Code trace
v Hardware service manager
v Main storage dump manager
v Product activity log
v Operator panel functions
v Performance data collector (available only on systems with SST)

IPL type, mode, and speed options

Set the initial program load (IPL) options from function 02 on the control panel. To permanently change
the IPL speed use the CHGIPLA command.
Note: Systems managed by the management console should use the management console to perform
control panel functions.
v Use function 01 to display the current IPL option, including IPL speed. This is the option and speed
that the system will use at the next IPL.
v Use the HDWDIAG (hardware diagnostics) parameter of the CHGIPLA command to permanently change the
IPL speed. The values are: The default shipped value *MIN (minimal) for fast diagnostics and *ALL for
all (full) diagnostics.
IPL speed recommendations
v Use CHGIPLA *MIN, or function 02 F or V=F for most IPLs (to perform a fast IPL that uses minimum
diagnostics).
v Use CHGIPLA *ALL, or function 02 S or V=S, if you change hardware or suspect an intermittent
hardware failure (to perform a slow IPL that uses all diagnostics).
v Use CHGIPLA *ALL, or function 02 S or V=S during the first IPL. You can set this at the panel with
Function 02; it affects only the one IPL because the next IPL will again pick up the value set with
CHGIPLA.
Printing the system configuration list and details of the system bus,
main storage, or processor
This information describes the system configuration list and how to print the list.
The System Configuration List printout consists of the following sections (80-character width):
1. System information
v System type, model, serial number, and release
2. Packaging hardware resource information
v Resource name, type-model, serial number, part number, frame ID, card position, and device
position
3. Logical hardware resource information
