Description
Media Manager Functional Description
tlhd The Tape Library Half-inch daemon works in conjunction with tlhcd to
handle requests to TLH robots that are in an IBM Automated Tape Library
(ATL). tlhd provides the interface between the local ltid and the robotic
control (tlhcd) in the same manner as explained previously for tl8d.
Started By: Starting ltid (or on UNIX, independently by using the
/usr/openv/volmgr/bin/tlhd command).
Stopped By: Stopping ltid (or on UNIX, independently by finding the
PID (process id) and then using the kill command).
Debug 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).
tlhcd The Tape Library Half-inch Control daemon provides robotic control for a
TLH robot that is in an IBM Automated Tape Library (ATL) in a similar
manner to that which was explained previously for tl8cd.
Started By: Starting ltid (or on UNIX, independently by using the
/usr/openv/volmgr/bin/tlhcd command).
Stopped By: Stopping ltid or by using the tlhcd -t command.
Debug Log: All errors are logged in the system log. Debug information is
included if the daemon is started with the -v option (either by itself or
through ltid). The -v option is available only on UNIX. Also, add the
VERBOSE option to the vm.conf file.
tlmd The Tape Library Multimedia daemon is the interface between ltid and a
TLM robot that is in an ADIC Distributed AML Server (DAS). This
daemon communicates with the TLM robotics through a network API
interface.
Started By: Starting ltid or independently by using the
/usr/openv/volmgr/bin/tlmd command.
Stopped By: Stopping ltid or independently by finding the PID
(process id) and then using the kill command.
Debug Log: All errors are logged in the system log. Debug information is
included if the daemon is started with the -v option (either by itself or
through ltid). The -v option is available only on UNIX. Also, add the
VERBOSE option to the vm.conf file.
