Problem Isolation Procedures
Bus, High-Speed Link (HSL) Problem Isolation Procedures
Overview
Note: Symbolic FRUs, FIs, and BUS PIPs will use the terms ″partition″ and ″logical
partition″ to indicate any single partition in a system which has multiple
partitions. If the system you are working on does not have multiple
partitions then the terms refer to the Primary partition.
Note: Migrated SPD busses from earlier AS/400 systems are not allowed to have
empty IOP card positions between IOPs. SPD busses are numbered from
0004 through 0017 in hexadecimal as they appear in the SRCs (see “Breaking
Down The SRC” on page 280). Empty card positions (between I/O
processors) are not allowed on the system SPD bus. Card gaps may cause
system reference codes (SRC) that provide incorrect FRU information. To
determine if there are any card gaps, select the Display card gap information
function key from the Hardware Service Manager display. If there are gaps,
correct the situation.
