ioscan lookalike for Linux

Bernhard Mueller — Tue, 16 Dec 2003 10:16:10 GMT

Hello,

as an HP-UX man I would like to know, if there is something similar to ioscan in any Linux distri.
Or perhaps at least something like prtdiag under Solaris...

Regards,
Bernhard

A check of google found
/sbin/lspci -v

It's not bad but it doesn't show disks. It a bit like Solaris prtdiag.

Not that I know, but

Under the /proc directory you will find all sort of information about loaded device and much more try

cat /proc/scsi/scsi
cat /proc/iomem
cat /proc/irq

etc..

Just be cautious about writing in /proc specialy if you are priviledged.

Thanks for the responses so far.

Actually, I was more looking for something to find out whether or not the machine can see and use devices such as LUNs on a dis array when I connect it to a fibre channel switch and put the WWN of its FC adapter into a storage zone.

Bernhard

Try

#cdrecord -scanbus

here is a cut and paste from the UNIX rosetta stone...

dmesg (if you're lucky)
/proc/*
lspci
(SuSE) hwinfo

What LUN's your particular HBA sees will be recorded under /proc/scsi//X

where X is some number...

e.g. my QLogic SCSI HBA sees 5 LUN's on my EMC frame.

$ cat /proc/scsi/qla2300/2
.
.
.
SCSI LUN Information:

I just checked out hwscan and hwinfo under suse. Very very useful. I haven't tried it under any other distro though. I just thought I'd add in in case you were looking at using SuSE.

Re: ioscan lookalike for Linux

Bernhard Mueller — Fri, 19 Dec 2003 09:05:41 GMT

hwinfo & hwscan seem indeed SUSE specific but the most useful tools.

you may try :
#lshw
for general hardware purpose
#scsiadd
For LUN scanning

Both are on Debian or a simple google search.
