Processes by robot type
Table: Robotic processes and robotic control processes
Automated Cartridge System (ACS)
The NetBackup ACS daemon acsd provides robotic control to mount and dismount volumes. It also requests inventories of the volumes that are under the control of ACS library software.
The NetBackup ACS storage server interface (SSI) event logger acssel logs events. UNIX and Linux only.
The NetBackup ACS storage server interface (SSI) acsssi communicates with the ACS library software host. acsssi processes all RPC communications from acsd or from the ACS robotic test utility that are intended for the ACS library software. UNIX and Linux only.
Tape library DLT (TLD)
The tape library DLT daemon tldd runs on a NetBackup server that has a drive in the tape library DLT. This process receives NetBackup Device Manager requests to mount and unmount volumes, and sends these requests to the robotic-control process, tldcd.
The tape library DLT Control daemon tldcd communicates with the tape library DLT robotics through a SCSI interface.
For library sharing, tldcd runs on the NetBackup server that has the robotic control.
