CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
If a good copy of the announcement file is not available, then the restore announcements opera-
tion cannot be executed until the 
save announcements command is successfully completed.
The announcements on the board are still accessible and usable.
Restore Announcements Command
The restore announcements command copies announcement data from the specified MSS dev-
ice to the announcement board (TN750).

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:
l No system access port is available (E39).
l 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...

Error Conditions
The following is a list of all error messages displayed to the user. If any of these error conditions
can be attributed to hardware failures or disk/tape configuration problems, they will be logged
with the maintenance subsystem. Error messages that are caused by a user entering improper
command operations will not be logged with the maintenance subsystem; the user is notified of
the error.
For each error message listed, an identifier is provided...

Announcement port in use; please try later.
One or more of the announcement ports are in use. The port could be in use for an
integrated announcements sessionor for integrated announcement playback.

This message indicates that the announcement file stored on disk or tape is corrupt.
A valid file must be stored on the MSS before it...

CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
Save Translation Command
The save translation command copies translation data from memory to the MSS. By default,
translation data is written to the primary MSS device in a simplex processor system, or to both
primary MSS devices in a duplicated processor system. In addition, the save translation com-
mand can be directed to write to devices on either of the processors and/or the secondary
device(s). The translation data can be automatically backed up as part of...

CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
Command Operation
The save translation command writes two time-stamped identical copies of translation data to
the selected device(s). The time stamp for both copies will be the same (it will be the time of writ-
ing to the first copy). Each copy is written as consecutive 2K blocks. Each block contains a
checksum for error detection purposes. Each copy contains a time stamp and the state of the
copy (either “good” or “bad”).
The save operation writes one complete...

The following operational rules apply to the save translation command:
1.
2.
3.
4.
5.
6.The 
save translation command will only be allowed if there are no translation updates
being made. All requests to update translation, after the command starts, will be denied
(E1).
If Terminal Translation Initialization (TTI) activation or deactivation is in progress, the
save translation command will be denied (E2).
The 
save translation command will not be allowed if the...

CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
Backup Command
Additional data integrity is achievable through disk to tape backups. These backups may be
done on demand or run daily as part of scheduled maintenance. This command is only valid in a
system which has both disk and tape as part of its MSS. The 
backup command will work in
either a simplex SPE or a duplex SPE system. When the command is run as part of scheduled
maintenance, the default for a simplex system is an incremental backup of SPE A. In a...

CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
Command Operation
When an incremental backup is performed, the following procedure governs this operation.
Before each file is copied from the disk to the tape, the file on the tape is marked as “bad.”
When the file has been completely copied over to the tape, the file is then marked as “good” on
the tape. This process ensures that if the system were to reboot in the middle of this operation,
files in the process of being copied will not be usable (on the tape)...
