This chapter describes error situations in the ROBAR system and how you must respond to them. Particular attention is paid to the preparation of diagnostic documents.
If an action causes the archive system to send an error message to ROBAR-SV, ROBAR-SV performs the necessary error recovery actions. The error recovery actions undertaken are of a general character that can also incorporate unnecessary actions (e.g. detachment of a device that has already been detached).
The error recovery actions are used to increase the availability of the archive system. They should not be interpreted as ROBAR errors.
In the majority of cases, the message of the archive system does not display error situations, rather it is used by ROBAR as the basis for executing requested actions. For this reason, such a message is generally not sent to the console. ROBAR checks the message to see whether it is one of the error messages defined in the error_defines file. If so, the actions specified there are executed and processing of the BS2000 job is aborted. If the error is not included in the error_defines file, the appropriate processing step in the message_xref is carried out.
If, on the other hand, the error is an irrecoverable error, the ROBAR message together with the error code of the archive system is sent to the appropriate console.
Information and diagnostic data
The ROBAR-SV Manager displays information on device and volume errors and the error limits for a ROBAR-SV instance. In addition, you can create current diagnostic data and statistics for a ROBAR-SV instance, see section "Diagnostic information on the ROBAR-SV instance".
This information is also available via corresponding menus of the robar menu program.
