Processes by robot type

The following table describes the robotic processes and robotic control processes for each robot type.

Description

Automated Cartridge System (ACS)

acsd

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.

acssel

The NetBackup ACS storage server interface (SSI) event logger acssel logs events. UNIX and Linux only.

acsssi

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)

tldd

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.

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.
