DISPLAY Monitor ROBAR actions

Application area:  SCSI and ABBA interface

The DISPLAY menu keeps you informed of current ROBAR actions and of the configuration, i.e. current device assignment for the ROBAR-SV instance selected in the INSTANCES menu.

You can select whether the configuration showing the current device assignment is to be displayed graphically or in the form of a table:

[g] or [ENTER]	configuration is displayed graphically
[t]	configuration is displayed in a table
[Ctrl]+[C]	return to main menu

If you choose one of the two display options, a follow-up screen that is divided into a number of sections appears:

• Title line
  Displays the application parameter currently valid.

• Upper section
  Displays all ongoing ROBAR actions, i.e. current communication between the ROBAR-SV instance and the archive system or between the ROBAR-SV instance and the BS2000 systems. Each archive system command sent from ROBAR-SV to the archive system is flagged with the current time. The ROBAR actions are also logged in trace files.
  A corresponding message is displayed when a connection between ROBAR-SV and ROBAR-CL is disrupted or lost.

• Middle section
  Displays all BS2000 systems connected to the ROBAR-SV instance. If a host is displayed in reverse video, it is attached; if displayed at reduced intensity, it is detached.

• Lower section
  Displays the MTC devices belonging to the configuration. Each device is identified by its device mnemonic, its associated BS2000 system and the volume (VSN) mounted in the device.
  If a device has the status DETACH PENDING, the BS2000 system identifier displays attached.

Graphical display of the configuration

Up to 18 devices and 40 BS2000 systems can be displayed. If a configuration contains more than 18 devices, you have to press the spacebar to display the next screen. If it contains more than 40 BS2000 systems, press the [h] key to display the next screen.

Figure 10:  DISPLAY screen, graphical display of the configuration

The title bar contains the following information:

Field name	Information	Value	Meaning
CONFIG	Name of the configuration file current being used
LOCATION	Name of the storage location defined in the configuration file
ROBAR	Status of the ROBAR-SV instance (if a robar_abba process is terminated abnormally, the displayed value is shown only at half intensity)	STOPPED	The ROBAR-SV instance has not been started yet.
		RUNNING	The ROBAR-SV instance is executing.
AMUx	Identifies the connected AMU (x=1 or 2) and the status. If the ROBAR-SV instance is running, the status is displayed as bright, otherwise the last known status is displayed at half-intensity	ACTIVE	The AMU is currently active
		PASSIVE	The AMU is currently inactive
		OFF	The AMU with which a connection is to be established cannot currently be accessed
ROB1	Status of the robot arm	ON	The robot arm is ready for use
		OF	The robot arm is not ready for use

The screen display is controlled by the following entries:

[Ctrl]+[C]	Terminate the DISPLAY menu, return to the main menu
[Space]	Display the next page with MTC devices (if the page displayed is the last one, the first page is displayed)
[h]	Display the next group with BS2000 systems (if the page being displayed is the last one, the first page is displayed)
[v]	Change from TSN to VSN display. If VSN display was already active, the effect is the same as pressing the space bar
[t]	Change from VSN to TSN display. If TSN display was already active, the effect is the same as pressing the space bar
[x]	Change between the tabular and graphical display format

You can switch between the VSN and TSN modes using the [v] and [t] keys. Pressing the same key twice does not change the mode (VSN or TSN). Instead the page is changed, i.e. the next group of devices is displayed.

Tabular display of the configuration

A maximum of 40 BS2000 systems and 45 devices can be displayed on the screen. To display more than this number, scroll forward. If a configuration comprises fewer than 45 devices, the upper area is extended accordingly. This means that the previous ROBAR actions remain visible for longer.

Devices which are entered in the configuration but do not belong to the archive are displayed at low intensity.

Figure 11: DISPLAY screen, tabular display of the configuration

The screen display is controlled by the following entries:

[Ctrl]+[C]	Terminate the DISPLAY menu, return to the main menu
[Space]	Display the next page with MTC devices (if the page displayed is the last one, the first page is displayed)
[h]	Display the next group with BS2000 systems (if the page being displayed is the last one, the first page is displayed)
[v]	Change from TSN to VSN display. If VSN display was already active, the effect is the same as pressing the space bar
[t]	Change from VSN to TSN display. If TSN display was already active, the effect is the same as pressing the space bar
[x]	Change between the tabular and graphical display format

You can switch between the VSN and TSN modes using the [v] and [t] keys. Pressing the same key twice does not change the mode (VSN or TSN). Instead the page is changed, i.e. the next group of devices is displayed.
