Floating Point Exerciser

The floating point exerciser is labeled procx, where x is the number of the processor containing the
floating point unit. The exerciser performs load/store and arithmetic operations using floating point registers
and instructions. The floating point instructions are executed using static values and the outcome of the
operation is compared with the expected result. Any mismatch results in an error condition. If the
processor is in use by the exerciser and is removed as a result of dynamic logical partitioning, the
exerciser terminates.

Save or Restore Hardware Management Policies

Use this service aid to save or restore the settings from Ring Indicate Power-On Policy, Surveillance
Policy, Remote Maintenance Policy and Reboot Policy. The following options are available:
v Save Hardware Management Policies
This selection writes all of the settings for the hardware-management policies to the following file:
/etc/lpp/diagnostics/data/hmpolicies
v Restore Hardware Management Policies
This selection restores all of the settings for the hardware-management policies from the contents of the
following file: /etc/lpp/diagnostics/data/hmpolicies
You can access this service aid directly from the AIX command line, by typing:
/usr/lpp/diagnostics/bin/uspchrp -a

SCSI Bus Analyzer

This service aid allows you to diagnose a SCSI bus problem in a freelance mode.
To use this service aid, the user should understand how a SCSI bus works. Use this service aid when the
diagnostics cannot communicate with anything on the SCSI bus and cannot isolate the problem. Normally
the procedure for finding a problem on the SCSI bus with this service aid is to start with a single device
attached, ensure that it is working, then start adding additional devices and cables to the bus, ensuring
that each one works. This service aid works with any valid SCSI bus configuration.
The SCSI Bus Service Aid transmits a SCSI Inquiry command to a selectable SCSI Address. The service
aid then waits for a response. If no response is received within a defined amount of time, the service aid
displays a timeout message. If an error occurs or a response is received, the service aid then displays one
of the following messages:
v The service aid transmitted a SCSI Inquiry Command and received a valid response back without
any errors being detected.
v The service aid transmitted a SCSI Inquiry Command and did not receive any response or error
status back.
v The service aid transmitted a SCSI Inquiry Command and the adapter indicated a SCSI bus
error.
v The service aid transmitted a SCSI Inquiry Command and an adapter error occurred.
v The service aid transmitted a SCSI Inquiry Command and a check condition occur.
When the SCSI Bus Service Aid is started a description of the service aid displays.
Pressing the Enter key displays the Adapter Selection menu. Use this menu to enter the address to
transmit the SCSI Inquiry Command.
