Disk and I/O Path Logging
Some failures result in I/O path logging. These paths help to indicate the source of the error and can be
included in the error message or logged into console or event logs.
Table 5-8 describes the disk drive and PCI slot paths for the server.
Table 5-9 lists the extended core I/O paths for the core I/O slot.
Table 5-10 lists the PCI I/O paths.
