Isolating problems on servers that run AIX or Linux

Use the procedures for AIX® or Linux servers if there is not a management console attached to the server. If the server is connected to a management console, use the procedures that are available on the management console to continue FRU isolation.

MAP 0210: General problem resolution
Replace the FRUs in the failing item list one at a time in the order that they are listed.
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.
SCSI service hints
Use one or more of the following procedures when servicing SCSI adapter or devices.
MAP 0020
Use this MAP to get a service request number (SRN) if the customer or a previous MAP provided none.
MAP 0030
This MAP is used for problems that still occur after all FRUs indicated by the SRN or error code have been exchanged.
MAP 0040
This MAP provides a structured way of analyzing intermittent problems.
MAP 0050
Use this MAP to analyze problems with a SCSI bus.
MAP 0054
Use this MAP to determine which FRUs may need to be replaced in order to solve a SCSI bus-related problem on a PCI-X SCSI or PCI-X SCSI RAID adapter.
MAP 0070
Use this MAP when you receive an 888 sequence on the operator panel display or monitor.
MAP 0220
Use this procedure to exchange hot-swappable field replaceable units (FRUs).
MAP 0230
Use this MAP to resolve problems reported by SRNs A00-xxx to A25-xxxx.
MAP 0235
Use this MAP to resolve problems reported by SRNS A11-560 to A11-580.
MAP 0260
Use this MAP when the system unit hangs while configuring a resource.
MAP 0270
Use this MAP to resolve SCSI RAID adapter, cache, or drive problems.
MAP 0280
Use this MAP to resolve console and keyboard problems when the system is booting.
MAP 0285
Use this MAP to handle SRN A23-001 and ssss-640 (where ssss is the 3 or 4 digit Failing Function Code (FFC) of an SCSD drive) to check the path from adapter to device.
MAP 0291
Use this MAP when a bus or device (such as a disk drive) is reported as a missing resource by the diagnostics.
MAP 4040
Use this MAP to resolve the following problem: Multiple controllers connected in an invalid configuration (SRN nnnn - 9073)
MAP 4041
Use this MAP to resolve the following problem: Multiple controllers not capable of controlling the same set of devices (SRN nnnn - 9074)
MAP 4044
Use this MAP to resolve an incorrect or incomplete multipath connection problem.
MAP 4047
Use this MAP to resolve the following problem: Missing remote controller (SRN nnnn - 9076)
MAP 4049
Use this MAP to resolve the following problem: Incomplete multipath connection between controller and remote controller (SRN nnnn - 9075)
MAP 4050
Use this MAP to perform SAS fabric problem isolation.
MAP 4052
Use this MAP to resolve device bus fabric problems.
MAP 4053
Use this MAP to resolve the following problem: Multipath redundancy level got worse (SRN nnnn - 4060)
MAP 4140
Use this MAP to resolve the following problem: Multiple controllers connected in an invalid configuration (SRN nnnn - 9073)
MAP 4141
Use this MAP to resolve the following problem: Multiple controllers not capable of controlling the same set of devices (SRN nnnn - 9074)
MAP 4144
Use this MAP to resolve an incorrect or incomplete multipath connection problem.
MAP 4147
Use this MAP to resolve the following problem: Missing remote controller (SRN nnnn - 9076)
MAP 4149
Use this MAP to resolve the following problem: Incomplete multipath connection between controller and remote controller (SRN nnnn - 9075)
MAP 4150
Use this MAP to perform SAS fabric problem isolation.
MAP 4152
Use this MAP to resolve device bus fabric problems.
MAP 4153
Use this MAP to resolve the following problem: Multipath redundancy level got worse (SRN nnnn - 4060)
MAP 5000
Use this MAP to resolve the following problem: The disk has failed and must be replaced.
MAP 5001
This event notifies the system administrator that there might be a data loss if the previously reported REPLACE_DISK events are not handled promptly.
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.
SAS fabric identification
Use this information to determine the FRUs to replace when there is a SAS fabric connection problem.
SAS RAID configurations
Use this information to determine which configurations are valid on the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, 8205-E6D, 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, 8268-E1D.
