Media Manager Functional Description
266 NetBackup Troubleshooting Guide - UNIX
tl8cd The Tape Library 8MM Control daemon provides the robotic control for a
TL8 robot and communicates with the robotics through a SCSI interface.
tl8cd receives mount and unmount requests from tl8d on the host to
which the drive is attached and then communicates these requests to the
robot.
Started By: Starting ltid (or on UNIX, independently by using the
/usr/openv/volmgr/bin/tl8cd command).
Stopped By: Stopping ltid or by using the tl8cd -t command.
Activity Log: All errors are logged in the system log. Debug information
is included by adding VERBOSE to the Media Manager configuration file,
vm.conf. On UNIX, debug information is also included by starting the
daemon with the -v option (either by itself or through ltid).
tldd The Tape Library DLT daemon works in conjunction with tldcd to
handle requests to TLD robots. tldd provides the interface between the
local ltid and the robotic control (tldcd) in the same manner as
explained previously for tl8d.
Started By: Starting ltid (or on UNIX, independently by using the
/usr/openv/volmgr/bin/tldd command).
Stopped By: Stopping ltid (or on UNIX, independently by finding the
PID (process id) and then using the kill command).
Activity Log: All errors are logged in the system log. Debug information
is included by adding VERBOSE to the Media Manager configuration file,
vm.conf. On UNIX, debug information is also included by starting the
daemon with the -v option (either by itself or through ltid).
tldcd The Tape Library DLT Control daemon provides robotic control for a TLD
robot in the same manner as explained previously for tl8cd.
Started By: Starting ltid (or on UNIX, independently by using the
/usr/openv/volmgr/bin/tldcd command).
Stopped By: Stopping ltid or by using the tldcd -t command.
Stopping ltid or tldd does not stop tldcd since it may be in use by
tldd on another host.
Activity Log: All errors are logged in the system log. Debug information
is included by adding VERBOSE to the Media Manager configuration file,
vm.conf. On UNIX, debug information is also included by starting the
daemon with the -v option (either by itself or through ltid).
