GPoppy — Tue, 08 Nov 2011 16:56:24 GMT

Hi, I just have a question about ioscan usage:

# ioscan -fnC target

Thank you.

Experimentation is usually the best to figure something out. Here's output from one of my systems:

Here's a full ioscan so you can see where the 'target's come from:

The TARGET is just that...the target device on the path. By itself it is not much, but combined with the previous entry (ext_bus for example) and the following entry (disk for example) in the IO tree you can see what that device is attached to and what that device is.
