About the required Linux SCSI drivers

To use SCSI tape drives and robotic libraries, the following drivers must be configured in the kernel or loaded as modules:

  • SCSI tape (st) driver.

  • Standard SCSI driver.

  • SCSI-adapter driver.

  • Linux SCSI generic (sg) driver. This driver allows pass-through commands to SCSI tape drives and control of robotic devices.

    NetBackup and its processes use the pass-through driver as follows:

    • To scan or discover drives

    • For SCSI reservations

    • For SCSI locate-block operations

    • For SAN error recovery

    • For Quantum SDLT performance optimization

    • To collect robot and drive information

    • To collect Tape Alert information from tape drives

    • For WORM tape support

    • For future features and enhancements

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
