To use SCSI tape drives and robotic libraries, the following drivers must be configured in the kernel or loaded as modules:
■ Linux SCSI generic (sg) driver. This driver allows pass-through commands to SCSI tape drives and control of robotic devices.
...
■ SCSI tape (st) driver. This driver allows the use of SCSI tape drives.
■ Standard SCSI driver.
■ SCSI-adapter driver.
The standard Enterprise Linux releases have the sg and the st modules available for loading. The modules are loaded as needed. Also, you can load these modules if they are not in the kernel. Use the following commands:
/sbin/modprobe st
/sbin/modprobe sg
