Observe the following important points when you configure the operating system:

• Verify that NetBackup supports your server platform and devices. The Veritas support Web site contains server platform compatibility information. For the compatibility information, see the NetBackup compatibility lists :

  http://www.netbackup.com/compatibility

• For SCSI controlled libraries, NetBackup issues SCSI commands to the robotic devices. For NetBackup to function correctly, the properly named device files must exist. Information about how to configure device files is available.

  See About configuring robot and drive control for Linux.

• Verify that a SCSI low-level driver is installed for each HBA in your system, as follows:

  • Follow the HBA vendor's installation guide to install or load the driver in the kernel.

  • Configure the kernel for SCSI tape support and SCSI generic support.

  • Probe all LUNs on each SCSI device and enable the SCSI low-level driver for the HBA.

  • Enable multi-LUN support for the kernel according to the Linux documentation.

  For more information, refer to your HBA vendor documentation.

• Multipath configurations (multiple paths to robots and drives) are supported only with the following configurations:

  • Native path (/dev/nstx, /dev/sgx)

  • The sysfs file system that is mounted on /sys

  • Native udev rules for persistent device paths (/dev/tape/by-path)
