CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
If restoring from tape, the restore announcements command will abort if no tape is in the tape
drive (E37).
The restore announcements command will also abort if:
● No system access port is available (E39).
● The MSS is in use by the SPE duplication memory refresh activity (E41).
Announcements on the ANN board will not be available until the restore operation is complete.
Treatment to calling users will vary according to the feature. Otherwise, normal call processing
service continues during the restore announoements operation.
The command completion status is displayed on the system administration terminal. The
displayed information includes a success or error message.
In case of a failure, it is the user's responsibility to make sure the announcement file is com-
pletely copied to the announcement board, although the system will continually attempt to down-
load the board in 10 minute intervals until a download is successful, announcements are
recorded, or a download is initiated from the system administrative terminal. The user should
take appropriate action based on the error message returned. If the error is the result of a
hardware or firmware failure, the MSS software will log a hardware error with maintenance.
Maintenance software will invoke tests to diagnose and attempt to correct the problem. If mainte-
nance software fails to correct the problem, an alarm would be raised and the system technician
should take appropriate action.
In the case where the system crashes and/or there is a processor interchange, the restore opera-
tion will fail. In this case, there will not be a valid announcement file on the announcement board.
The command should be restarted on the newly active processor to copy the announcements
from the active processor's MSS device to the announcement board. Until the announcements
are successfully and completely copied to the announcement board, calls will not be connected to
any announcements on the ANN board.
When the ANN board is plugged in or reset, maintenance
will perform a series of tests, including
a DRAM Checksum test. The teat will fail due to the power loss to the board, resulting in
automatic downloading of the announcement file.
