Effectivly, it mens your drives are 'standalone' or 'not robotic'.

If you have a standalone drive on a server, it will correctly show as AVR.

If you have a robot and drives, the drives should correctly show as 'TLD' or 'ACS' or xxx where xxx is the robot type.

If, for some reason, your drives stop showing TLD (or ACS or whatever) and show AVR it means that NetBackup thinks the drives are now non-robotic, by far the most common reasons for this are (considering an SSO environment).

If all the drives on all the media servers including the robot control host are AVR, the RCH has lost communication with the library.  This is usually a SAN issue.

If the drives on the robot control host show 'TLD', but drives on seperate media servers show AVR, then the media servers showing AVR have lost communication to the robot control host (usually a network issue).  The reson being, each media server with robotic drives, has to talk to the robot control host to get tapes loaded/ unloaded.

A less common reason, is that the drives were configured as standalone.  This usually only happens on 'new systems' when the device wizard is run without selecting the robot control host.  This means NetBackup scans the other media server(s), but as it yet doesn't know about the library itself (becasue the RCH hasn't been configured) then it doesn't know the drives are in a robot, and so they end up configured as standalone, and show as AVR.

Thanks alot for valuable information
