Linux (kernel 2.6.x) servers and workstations

Determining the SCSI ID

Look at the output of dmesg to find out what SCSI channel number is used for each connection.
To find out the SCSI IDs in use on each channel, type:
cat /proc/scsi/scsi
This will produce output similar to the following for each device:
Attached Devices
Host: SCSI0 Channel: 00 Id:00 Lun:00
Vendor: HP Model ------------
Type: Direct-Access ANSI SCSI Revision 02
Look at the ID information to establish which IDs are in use.

Configuring on Linux systems

No changes are needed to support LTO Ultrium on Linux platforms, however you should ensure that
you have the relevant drivers loaded.
To see the device drivers loaded currently, execute lsmod. This will give output similar to:
Module
sgm
ide-scsi
lockd
sunrpc
st
sym53c8xx
aic7xxx
The lines of interest here are:
st
sym53c8xx The SCSI chipset driver for the LSI Logic family of HBAs (amongst others).
aic7xxx
Latest SCSI controller drivers for Linux are available from the manufacturer's web site.
In order to communicate with a tape device, the operating system needs to have drivers for the tape
and the underlying transport mechanism (the host bus adaptor) loaded. Ensure that both are
available as either loadable modules (for example, usable with insmod and visible with lsmod)
or are statically built into your kernel.
