The following modes are available:
Service mode
This mode requires a service mode boot of the system and enables the checking of
system devices and features. Service mode provides the most complete self-check of the
system resources. All system resources, except the SCSI adapter and the disk drives that
are used for paging, can be tested.
Concurrent mode
This mode enables the normal system functions to continue while selected resources are
being checked. Because the system is running in normal operation, certain devices might
require extra actions by the user or a diagnostic application before testing can be done.
Maintenance mode
This mode enables the checking of most system resources. Maintenance mode provides
the same test coverage as service mode. The difference between the two modes is the
way that they are started. Maintenance mode requires that all activity on the operating
system is stopped. Run shutdown -m to stop all activity on the operating system and put
the operating system into maintenance mode.
The system management services (SMS) error log is accessible on the SMS menus. This
error log contains errors that are found by partition firmware when the system or partition is
booting.
The service processor's error log can be accessed on the ASMI menus. You can also access
the system diagnostics from a Network Installation Management (NIM) server.
Alternative method: When you order a Power E850C, a DVD-RAM drive is available as
an option. An alternative method for maintaining and servicing the system must be
available if you do not order the DVD-RAM drive.
Depending on the operating system, the following service-level functions are what you
typically see when you use the operating system service menus:
Product activity log
Trace Licensed Internal Code
Work with communications trace
Display/Alter/Dump
Licensed Internal Code log
Main storage memory dump manager
Hardware service manager
Call Home/Customer Notification
Error information menu
LED management menu
Concurrent/Non-concurrent maintenance (within scope of the OS)
Managing firmware levels:
– Server
– Adapter
Remote support (access varies by OS)
Service Focal Point on the Hardware Management Console
Service strategies become more complicated in a partitioned environment. The Manage
Serviceable Events task in the management console can help streamline this process.
Each logical partition reports errors that it detects and forwards the event to the Service Focal
Point application that is running on the management console, without determining whether
