I need some command that give me information like "ioscan command".

There is a utility called 'lshw' that will gather and display this info for you

It parses through the /proc area and displays the stats relevant to your system

Check out the following URL

Use the 'lshw -short' command syntax, looks like ioscan

Rick, I just executed the guidelines "How to install the lshw", but only source file appear on the server, all seems to be right when executed the command "make" and "rpmbuild -ta lshw-B.02.05.01".

Below, it is part of output from installation script:

Rick, excuseme.. you are right,now I can use lshw..

If I can reassign points, you have 10pts now.

Thanks a lot..

With the lshw utility you can do 'lshw -short' and get a output similar to ioscan.

Doing the 'lshw' will get you a longer output.

Doing 'lshw -html' will get yopu a html output that you can view in your browser.

Using the 'lshw -short' option, it shows you have disk(s) but will noit show size. Using the long or html option will display the info for you.

There will be a stanza of output for each disk that is discovered. This includes the html output.

How about "cat /proc/partitions" or "format .." with the correct parameters?

Would you necessarily install a utility on a production host if you can get away with just using the native OS commands?

My 2 cents worth...

Try "fdisk -l" this should show all the partitions that Linux can see.
