CHAPTER 7. SYSTEM BACKUP FOR DEFINITY G1 AND G3i
Tape Backup for a System Without the Duplication Option
Two cassette tapes are provided with the system. It is recommended that backup copies of
the translation data be made weekly, or after many changes have been made to the translation
data. This will minimize the loss of recent translation data changes if the cassette tapes in the
system become damaged.
The following procedure can be used to make a backup tape:
1. Remove the cassette tape from the tape...

Tape Backup for a System With the Duplication Option
Four cassette tapes are provided with the system. It is recommended that backup copies of
the translation data be made weekly, or after many changes have been made to the translation
data. This will minimize the loss of recent translation data changes if the cassette tapes in the
system become damaged.
The following procedure can be used to make backup tapes:

Tape Errors
Since the tape drive is a mechanical device, tape-related failures may occur. When these
failures occur, the system responds with “tape error messages”. The following is a list of the
tape error messages and recommended responses to each. Check for proper operation after
each response is done.

Tape access error: no tape cartridge or device problem
Indicates that the cassette tape is missing or improperly seated. This error can...

6. Internal translation data is corrupted
Indicates that the translation data is inconsistent and the translation was not saved on
tape.
Response: Replace cassette tape with system backup tape.
Enter the command reset system 3. After the command completes, remove the backup
tape, install the original tape, and then repeat the command that generated the error
message. Notify maintenance support if the same error message is displayed again.

CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
Overview
The DEFINITY G3r Mass Storage System (MSS) utilizes tape and disk to provide stable storage
of switch data. MSS configurations include single Switch Processing Element (SPE) and dupli-
cated systems. There are four basic MSS configurations:
Simplex Tape-Only
In a simplex tape-only system, the tape drive 
is the primary MSS device.
In this configuration, there is no alternate means to boot the system or
save...

Command Interface Conventions
In the following sections, the commands used to interface with the MSS are described. The con-
ventions used to describe the commands are:
Optional Command ArgumentsA set of brackets [ ] is used to designate optional groups of
arguments to a command. One item listed within each set of
brackets can be specified on the command line.
Error Conditions
Following the descriptions of the command operations is a list
of error conditions...

CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
Invoking the save announcements command with the either option forces the system to write
the announcements data to the specified device in both mass storage systems concurrently. If
there is a failure in accessing one of the devices, the announcements data will still be written to
the device that has not failed.
The 
[disk | tape] options specify the device on which to save the announcements data. These
options only apply in a system with a disk.
Invoking the...

CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
If the user requests that announcements be saved to a tape, the tape must be in service (E14).
If the user requests that announcements be saved to the standby processor, the standby proces-
sor must be in service and shadowing must be enabled (E16).
If an error is encountered in the above steps, the save operation is not attempted.
When MSS devices on both processors in a duplicated system are specified, the save announce-
ments operation will save announcement...
