Improved ioscan(1M) Description Field for
PCI Devices
The ioscan (1M) command displays I/O devices, memory modules, and
CPUs in a tabular form for users.
Previously, PCI interface cardswere listed inthe ioscan output by cryptic
values in the ioscan description field. These values have been replaced
by PCI device header fields which provide a clearer description for most
(common) devices. See the example provided below.
The changes are:
• Dropped “FRU” info. When PCI drivers update the description fields
(as the SCSI interface driver scsi_c720 currently does), this gets lost
anyway. For more information on the SCSI interface driver, see “SCSI
Interface Driver scsi_c720” on page 54 in Chapter 3.
• Added lookup of the class/subclass headers for most PCI specified
devices (for example, PCI Ethernet). This provides useful and correct
information when a device driver is not loaded or does not update the
description.
• Dropped “PCI Bus Bridge” to shorten the CDIO description string.
Epic CDIO would result in “EPIC Bridge”. “PCItoPCI” is the name of
the new CDIO for PCI-to-PCI Bridges (PPBs).
This is the old output:
H/W Path Class Description
8 bc Pseudo Bus Converter
8/0 ba PCI Bus Bridge - GSCtoPCI
8/0/1/0 ba PCI(10110024)
8/0/1/0/4/0 lan PCI(10110019)
8/0/1/0/5/0 ext_bus Ultra Wide SCSI
8/0/1/0/5/0.1 target
8/0/1/0/5/0.1.0 disk HP C2247WD
Here’s the new output:
H/W Path Class Description
8 bc Pseudo Bus Converter
8/0 ba GSCtoPCI Bridge
8/0/1/0 ba PCItoPCI Bridge
