Isolation procedures

Isolation procedures are used together with diagnostic programs, which are part of server firmware.

If a server is connected to an HMC, these procedures are available on the HMC. Use the HMC procedures to continue isolating the problem. If the server does not have an HMC and you are directed to perform an isolation procedure, the procedures documented here are needed to continue isolating a problem.

HSL/RIO 12X isolation procedures
Use RIO/HSL/12X isolation procedures if there is no HMC attached to the server. If the server is connected to an HMC, use the procedures that are available on the HMC to continue FRU isolation.
Bus, high-speed link (HSL/RIO/12X) isolation information
Symbolic FRUs, failing items, and bus isolation procedures use the terms partition and logical partition to indicate any single partition in a system that has multiple partitions. If the system you are working on does not have multiple partitions, then the terms refer to the primary partition.
Multi-adapter bridge isolation procedures
Use multi-adapter bridge (MAB) isolation procedures if there is no HMC attached to the server. If the server is connected to the HMC, use the procedures that are available on the HMC to continue FRU isolation.
Communication isolation procedure
Isolate a communications failure.
Disk unit isolation procedure
Provides a procedure to isolate a failure in a disk unit.
Intermittent isolation procedures
These procedures help you to correct an intermittent problem.
I/O processor isolation procedures
Isolate a failure in the multiple function I/O card.
Licensed Internal Code isolation procedures
Use this section to isolate Licensed Internal Code problems.
Logical partition isolation procedure
Identify logical partition (LPAR) configuration conditions and the associated corrective actions.
Operations console isolation procedures
These procedures help you to isolate a failure with the Operations Console.
Power isolation procedures
Use power isolation procedures for isolating a problem in the power system. Use isolation procedures if there is no HMC attached to the server. If the server is connected to an HMC, use the procedures that are available on the HMC to continue FRU isolation.
Router isolation procedures
These procedures serve as a guide to the correct isolation procedures from the reference code tables.
Serial-attached SCSI isolation procedures
Use serial-attached SCSI (SAS) isolation procedures when an HMC is not attached to the server. If the server is connected to an HMC, use the procedures that are available on the HMC to continue FRU isolation.
Service processor isolation procedures
Use service processor isolation procedures if there is no HMC attached to the server. If the server is connected to an HMC, use the procedures that are available on the HMC to continue FRU isolation.
Tape unit isolation procedures
This topic contains the procedures necessary to isolate a failure in a tape device.
Isolating problems on servers that run AIX or Linux
Use the procedures for AIX® or Linux servers if there is not an HMC attached to the server. If the server is connected to an HMC, use the procedures that are available on the HMC to continue FRU isolation.
