ABBA interface
Defines how the virtual archive system ETERNUS CS is controlled by ROBAR.
actions
Actions are defined by the user in the ROBAR rule files (RRFs) for every BS2000 console message, and consist of:
- archive system actions (mounting, dismounting cartridges etc.)
- BS2000 system actions (responding to console messages etc.)
archive numbers
Each cartridge has a 6-digit archive number under which it is known in the archive system. This number must be identical with the volume serial number (VSN) with which the cartridge was initialized in the BS2000 system. The VSN is the identifier by which the cartridge is known to the BS2000 system. In this manual the terms “archive number” and “VSN” are used synonymously. “Archive number” may not be confused with the “number of the archive”.
archive record (also: archive database)
Database containing the logical and physical information on cartridges, MTC drives and robots. This is also where the archive numbers of a cartridge and its respective storing position are specified. The archive record is administered by ROBAR-SV at the SCSI interface. It is administered by the ETERNUS CS software at the ABBA interface.
archive system
One of the MTC archive systems supported by ROBAR when the archive systems do not need to be distinguished further.
ROBAR
The software product that controls archive systems from BS2000 systems. ROBAR consists of the parts ROBAR-SV and ROBAR-CL.
ROBAR rule files (RRFs)
Files that define which messages the archive system is to react to and how ROBAR has to react to feedback information from the archive system.
ROBAR server
Server on which ROBAR-SV runs.
robar_abba
The component of ROBAR-SV for communicating with the archive system, consisting of several cooperating background processes.
robar_mon
The monitor for ROBAR-SV communication with up to 110 BS2000 systems with the help of the software product CMX.
ROBAR-CL
Locally available component for linking a BS2000 system and the ROBAR server consisting of ROBAR-CL-DCAM and ROBAR-CL-SDF.
ROBAR-CL-DCAM
DCAM application of ROBAR-CL with UCON authorization which forwards console message which are relevant to ROBAR to ROBAR-SV and receives requests from ROBAR-SV for a BS2000 system.
ROBAR-CL-SDF
BS2000 user program for entering organizational statements for MTCs in the archive system. Transfer to ROBAR-SV takes place using ROBAR-CL.
ROBAR-freepool
Directory in which the archive numbers (VSNs) of the SCRATCH cartridges are stored.
ROBAR-SV
The central ROBAR part for communicating with the archive system and a maximum of 110 BS2000 systems. ROBAR-SV runs on the ROBAR server.
ROBAR-SV instance
A ROBAR-SV instance operates an archive system or one of its partitions.
ROBAR-SV Manager
The ROBAR-SV Manager is a web application for operating the ROBAR-SV instances on the ROBAR server.
SCRATCH cartridges
MTCs mounted in response to non-specific volume requests (VSN = *SCRAT, *UNKNO).
SCSI interface
Defines how the real archive systems Scalar i500 and i6000 are controlled by ROBAR.
VAMU
Interface for controlling the virtual robot in ETERNUS CS.
