About SAN clients on Linux
NetBackup SAN clients on Linux hosts require the SCSI Generic (sg) driver and pass-through tape drive device files for traffic to NetBackup FT media servers. The media server FT devices appear as ARCHIVE Python tape devices during SCSI inquiry from the SAN client. (However, they are not tape devices and do not appear as tape devices in NetBackup device discovery.)
You should verify that you have the correct driver and device files.
If your Linux operating system does not add all of the SCSI device files automatically, you can do so manually. The following is an example of code you can include in the /etc/rc.local file to add LUN 1, targets 0-7 on Controllers 0-2. Note that the last line is the MAKEDEV command, which makes the required device files. The code you include in your /etc/rc.local file depends on how your hardware environment.
