About SCSI and FCP robotic controls on Solaris
When you configure the NetBackup sg driver, a NetBackup script creates the device files for the attached robotic devices.
See About the NetBackup sg driver.
If you use device discovery in NetBackup, NetBackup discovers the robotic control device files in the /dev/sg directory (and hence the devices) automatically. If you add a robot manually in NetBackup, you must enter the pathname to the device file.
To display the device files that the sg driver can use, use the NetBackup sgscan command with the all parameter. The word "Changer" in the sgscan output identifies robotic control device files.
Examples are available.
