Service reference procedures
The service reference procedures include general tasks such as setting the system date and time, setting the system password, determining the dominant operating system, accessing the history file, and so on.
- Setting the system date and time
The system date and time can be set with various tools. - Determining the dominant operating system
How to determine the dominant operating system. - System password
If a system password is required, the Verification of System Password Failed display appears just prior to the IPL or Install the System display. - System unique identifier
The system unique identifier (SUID) is a 12-character ID that is assigned by the manufacturer. - Primary consoles
A console is a workstation that is used to view and control system operations. - Locating the system's load source from the system console
Use this procedure to locate the system load-source and alternate load-source input/output processors (IOPs), load-source I/O adapter, and load-source disk unit. - History file
The history file provides a high-level audit trail of the actions that are performed by the system. - Low-level debug and data collecting procedures
Use these procedures to collect data for problems with Licensed Internal Code or hardware that you have been unable to solve with other methods. - Logical partitions
Logical partitions are the distribution of resources within a single system to make it operate as if it were two or more independent systems. - Independent auxiliary storage pool and clustering
These service reference procedures include determining whether an expansion unit is switchable, and determining the power controlling and current logical system ownership of an expansion unit. - Adding expansion units to a large configuration with SPCN firmware update control
You can add expansion units to a running system with 10 or more expansion units, including those being added with SPCN firmware update control.
