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 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 Windows systems, the
Internet service port number for acsd
must be in %SystemRoot%\system32\drivers\etc\services. To
override the services file, create the file install_path\Volmgr\database\ports\acsd
with a single line that contains the service port number for
acsd. The default service port number
is 13702.
