About this task
Configuring Tivoli Storage Manager passthru drivers for tape devices and libraries
To use the Tivoli Storage Manager Linux Passthru driver, you must complete the following steps.- Installing zSeries Linux fibre-channel adapter (zfcp) device drivers
The zSeries® Linux Fibre Channel adapter (zfcp) device driver is a special adapter driver on the IBM® zSeries system. It provides a standard SCSI interface for up level SCSI device drivers in Linux operating systems on zSeries platforms. It is used with two support modules - qdio for qdio devices and scsi_mod, for general SCSI support. - Information about your system's SCSI devices
Information about the devices seen by your system is available in the file /proc/scsi/scsi. This file contains a list of every detected SCSI device. - Preventing tape labels from being overwritten
The Tivoli Storage Manager Passthru device driver uses the Linux SCSI generic device driver (sg) to control and operate tape devices attached on the system. If the Linux generic SCSI tape device driver (st) is loaded to the kernel and configures attached tape devices, conflicts can arise over how a device is managed because the generic sg driver and the st driver can both control the same device.
