Analyzing problems
Use these instructions and procedures to help you determine the cause of the problem.
- Problems with loading and starting the operating system (AIX and Linux)
If the system is running partitions from partition standby (LPAR), the following procedure addresses the problem in which one partition will not boot AIX® or Linux while other partitions boot successfully and run the operating system successfully. - PFW1540: Problem isolation procedures
The PFW1540 procedures are used to locate problems in the processor subsystem or I/O subsystem. - PFW1542: I/O problem isolation procedure
This I/O problem-determination procedure isolates I/O card and I/O subsystem failures. When I/O problem isolation is complete, all cables and cards that are failing will have been replaced or reseated. - PFW1548: Memory and processor subsystem problem isolation procedure
Use this problem isolation procedure to aid in solving memory and processor problems that are not found by normal diagnostics. - Problems with noncritical resources
Use this procedure to help you determine the cause of problems with noncritical resources. - Intermittent problems
An intermittent problem is a problem that occurs for a short time, and then goes away. - IPL problems
Use these scenarios to help you diagnose your IPL problem. - Power problems
Use the following table to learn how to begin analyzing a power problem.
