Determining the SCSI ID (Linux)

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 Ultrium on Linux platforms, however you should ensure that you have the relevant drivers loaded.

To see the device drivers loaded currently, execute an lsmod command, this will give output like:
