acsd — Automated Cartridge System (ACS) daemon (UNIX) or process (Windows)
On UNIX systems, the directory path to this command is /usr/openv/volmgr/bin/
On Windows systems, the directory path to this command is install_path\Volmgr\bin\
acsd interfaces with Media Manager to mount and unmount tapes automatically that are under Automated Cartridge System (ACS) control. If the Media and Device Management of the Administration Console shows drives in an ACS robot, the ltid NetBackup Device Manager daemon or service (Windows) runs acsd. Stopping ltid stops acsd.
On UNIX systems, start or stop acsd independently of ltid by using
/usr/openv/volmgr/bin/vmps or your server's ps command to identify the acsd process ID. Then enter the following commands:
kill acsd_pid /usr/openv/volmgr/bin/acsd [-v] &
acsd performs its tasks by sending requests to the ACS storage server Interface process (acsssi). It communicates with the server that controls the ACS.
On Windows systems, acsd performs its tasks by sending requests to the STK LibAttach service, which communicates with the server that controls the ACS.
When the connection is established, acsd puts the ACS robot in the UP state and can mount and unmount tapes. If the connection cannot be established or ACS errors exist, acsd changes the robot to the DOWN state. In this state, acsd still runs and returns the robot to the UP state when the problem no longer exists.
Use the following to address and define drives in the Media Manager: ACS number, LSM number, Panel number, and Drive number.
Configure drive cleaning for ACS robots by using ACS library software. You cannot define the cleaning volumes by using Media Manager. In addition, you cannot use the tpclean command for cleaning operations on drives under ACS robotic control.
On UNIX systems, the Internet service port number for acsd must be in
/etc/services. If you use NIS (Network Information Service), place the entry in this host's
/etc/services file in the master NIS server database for services. The default service port number is 13702.
On Windows systems, the Internet service port number for acsd must be in
%SystemRoot%\system32\drivers\etc\services. The default service port number is 13702.
This command applies only to the NetBackup Enterprise Server.
This option is used on UNIX systems only. It logs debug information using syslogd. If you start ltid with -v, acsd also starts with -v.
On UNIX systems, acsd returns an error message if a copy of acsd is in operation. Media Manager logs ACS and network errors to syslogd. Log entries are also made when the state changes between UP and DOWN. acsssi logs to a log file in the
On Windows systems, Media Manager logs ACS and network errors to the Windows application event log. Log entries are also made when the state changes between UP and DOWN.
