RE: IOScan for HP-UX but how about linux?

[Charles Ooi Chia Lun]

Dear Sir,
In HP-UX we use Ioscan to scan all the hardware existence on our systems. How about Linux? Thank you.

Regards

on a few RHEL ES and AS boxes I used to manage, there was a util I used called "hardware lister". It did a pretty good job and helped dump the data into an "ioscan" like output. Also offered detailed output w/ html format.

You can find lshw here
http://ezix.sourceforge.net/software/lshw.html

Hope this helps,

Any detected HW that your running kernel supports can be found beneath /proc
Also for plug-in devices such as USB attached HW there will a detection message immediately be sent to console as well as /var/log/messages.
Additionally you can issue dmesg for boot up HW detection messages, and to scan your PCI bus you can issue lspci.

[Ralf Hildebrandt]

1) lspci lists all devices on the PCI bus.
2) dmesg also give a good hint on what the kernel already detected.
3) Booting into knoppix from CD also gets a lot of hardware discovered.

[Ross Minkov]

If you want ioscan like output use:

# lshw -short

For example on my server I get this as output:

H/W path Device Class Description

/0/1000/2 memory DIMM DDR Synchronous 266 MHz (3.8 ns)
/0/1000/3 memory DIMM DDR Synchronous 266 MHz (3.8 ns)


You can get lshw from http://ezix.sourceforge.net/software/lshw.html.

Try also:

# lshw -C system


Also try this:

# lspci -tv

lspci will list all PCI devices; lspci is a utility for displaying information about all PCI buses in the system and all devices connected to them.

-v Tells lspci to be verbose and display detailed information about all devices.
-t Show a tree-like diagram containing all buses, bridges, devices and connections between them.

I've seen a few ports of ioscan for *nix, but I've found that cat /proc/scsi/* works pretty well for my needs...

[Paul Cross_1]

This has been discussed here many times. You should try searching for "ioscan linux". Here are a few of the results:
