Viewing System Configuration with ioscan

HP-UX version 11.00.01 Getting Started 1-7

Here are some sample device special files and their possible meanings:

Both lssf and ioscan commands display the interface to which a device is

connected. These are discussed in the following sections.

Viewing System Configuration with ioscan

The ioscan command is the most versatile standard tool in the HP-UX operating

system for displaying your system configuration. For example, you can use

ioscan to identify available hardware addresses.

On Continuum systems, you can also use ftsmaint to identify available

hardware addresses, as well as for other administration tasks. See “Using ftsmaint

to Administer System Hardware” later in this chapter and the ftsmaint(1M) man

page for a description of ftsmaint features.

Terse Listing of ioscan

In its simplest form, ioscan displays hardware path, device class, and

description. The -u (usable devices) or -k (kernel structures) options give the

fastest response because they do not probe the hardware. See Figure 1-1 for a

sample of the output on a Continuum system.

/dev/rdsk/c0t2d0 Entire disk accessed in character (raw) mode

through SCSI card instance 0, target 2, LUN 0.

/dev/rmt/c1t0d0BESTnb Tape drive accessed through card instance 1,

target 0, LUN 0. Tape writes at best available

density/format, no rewind, Berkeley-style close.

/dev/rmt/0mnb Tape drive device special file with identical

characteristics (linked) to

/dev/rmt/c1t0d0BESTnb.
