Linux (kernel 2.6.x) servers and workstations

NOTE: USB, SCSI and SAS drives are supported on Linux kernel 2.6.x.

Determining the SCSI ID

Look at the output of
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 DDS-format drives on Linux platforms, however you should
ensure that you have the relevant drivers loaded.
To see the device drivers loaded currently, execute an
Module
sgm
ide-scsi
lockd
sunrpc
st
sym53c8xx
aic79xx
scsi_mod
The lines of interest here are:

sym53c8xx
aic79xx
Latest SCSI and SAS controller drivers for Linux will be 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
to find out what SCSI channel number is used for each connection.
