Hi Sumair

Wrong forum !!!

Anyway, you can use dmesg for hardware detection.

You can see if they are attached by checking /proc/scsi/scsi. Below is an example.

# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: IBM Model: 03590B1A Rev: B6C6
Type: Sequential-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: IBM Model: 03590B1A Rev: A558
Type: Sequential-Access ANSI SCSI revision: 03
Host: scsi1 Channel: 00 Id: 00 Lun: 00

With the qlogic HBA, I used scli.
Also lsscsi might be helpfull.

Thanks for prompt replies.


But I cannot see new attached tape drives with

cat /proc/scsi/scsi
Do it need rescan.

Is there any way to rescan attached devices.

Hi Farrukh, if you have a Proliant Server with "Proliant Support Pack " installed into the system or HP Itanium server with Support Pack and hp qlogic specific drivers, check for this packages:

# rpm -qa | grep fibreutils


If you have the fibreutils package installed onto your system then:

To view tapes and disk...

# lssg (or lssd)

To rescan all HBAs (if PSP installed)

# hp_rescan -a

Best Regards

There is a script that will rescan the bus and add new devices. It is called rescan-scsi-bus.sh I have used it many times to add fibre attached tape devices without a reboot. I don't remember where I got it, but I do remember a simple google search turned up lots of results for it.

Drivers can always be an issue as well. Also double check the zoning of any switches if the drives aren't direct attached.
