Service Agent for the Eserver pSeries 690

Service support for the Eserver pSeries 690 can be enhanced through the use of the application program
known as service agent for the Eserver pSeries 690. This application provides a number of advantages
for the Eserver pSeries 690 customer, including automatic error reporting and analysis without customer
intervention. Everything needed to use the service agent on the Eserver pSeries 690 is shipped with the
system or with the Hardware Management Console for pSeries.

Using the Service Processor and Service Agent Features

The service processor and service agent features protect users against unnecessary system downtime by
advising support personnel (both internal and external) of any unexpected changes in the system
environment. In combination, the two features provide a flexible solution to automated system
maintenance. For more information regarding the service processor, see Chapter 7, "Using the Service
Processor," on page 783. For more information regarding the service agent application, see the IBM
Hardware Management Console for pSeries Installation and Operations Guide.
Running Diagnostics on the Native Serial Port on a Full Machine
Partition with an HMC Attached
For a full system partition, the output of the S1 serial port is redirected, or wrapped to the virtual console
window. When the S1 serial port is wrapped, the output of any command is directed from the S1 serial
port to the virtual console terminal. If you close the virtual console window on the managed system,
normal function is restored to the S1 serial port.
The implication of this is that the serial port wrap diagnostics may fail with a false SRN if the virtual
console window on the managed system is not closed. Another method to prevent the false SRN is to
unplug the HMC from its port before running the wrap tests.
After running diagnostics on the serial port, make sure that the S1 serial port is enabled for login; use the
AIX command chdev -l 'ttyx' -a login='enable' where x is the tty number corresponding to the S1 serial
port.
