b For commands that use density and tape size settings, the tape:
• Density is 124,000 bpi
• Length is 1800 feet
This subsection provides procedures for configuring Linux UNIX
operating system environments.
Use the following command to list the current SCSI controllers:
3
dmesg | grep SCSI
This command produces output similar to:
(scsi0)<Adaptec AHA-294XX Ultra2 SCSI host
adapter> found at PCI 0/16/0
Use the following command to find existing SCSI devices:
cat /proc/scsi/scsi
This command produces output similar to:
Host: scsi0 Channel: 0 Id:6 Lun:00
Vendor: Quantum Model: ULTRIUM 3 Rev: 1897
Type: Sequential-Access ANSI SCSI revision 04
Use the output of these two commands to determine which SCSI target
ID numbers are available. In this example, a tape drive is attached at
target ID 6.
The widely available distributions of Linux automatically install the
proper SCSI and tape device drivers. If you executed the
find existing SCSI devices, you have ensured that the SCSI driver for your
controller is installed.
