Viewing System Configuration with ioscan

HP-UX version 11.00.01 Getting Started 1-9

Figure 1-2. Sample ioscan -H Output

The hardware path can be decoded as follows:

Field separators (slash (/) or dot (.)) separate the numbers of the hardware

address and have no bearing on system administration. The displayed classes are

more meaningful in the context of instance numbers. Instance numbers are visible

in ioscan -f listings, and are discussed later in this chapter.

Understanding the Description in ioscan

The description field displayed by ioscan derives from the peripheral device

itself, and is sometimes more cryptic than is ideal. Typically, a numeric description

refers to the manufacturer’s vendor ID, and in some cases, this number

corresponds to more than one model number. If you are troubleshooting a

peripherals problem, the description is often useful information to a Stratus

support engineer.

Full Listing of ioscan

The ioscan -f command displays full information about the Continuum system

configuration, including instance number, device/interface driver, software state,

and hardware type. The -fn option displays the device special files also.

Figure 1-3 shows sample ioscan -f output.

0 identifies the system bus

4 identifies the location of the bus adapter connecting the device (in

this example, the HSC Nexus or high-speed communications bus)

to the system bus

0 identifies a transparent layer between the Nexus bus and the SCSI

interface

1 identifies the slot number of the SCSI interface
