4.7.2 Physical channel report
A PCHID reflects the physical location of a channel-type interface.
A PCHID number is based on these factors:
The I/O drawer, and PCIe I/O drawer location
The channel feature slot number
The port number of the channel feature
A CHPID does not directly correspond to a hardware channel port, but it is assigned to a
PCHID in the HCD or input/output configuration program (IOCP).
A PCHID report is created for each new build server and for upgrades on existing servers.
The report lists all I/O features that are installed, the physical slot location, and the assigned
PCHID. Example 4-2 shows a portion of a sample PCHID report. For more information about
the AID numbering rules for InfiniBand and PCIe fanouts, see Table 4-4 on page 153.
