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 regularly scheduled
maintenance. It is recommended that automatic backup be performed on a daily basis.
Command Syntax
save translation [active | standby | SPE_A | SPE_B | both | either] [disk
|
tape]
The bracketed options specify which mass storage system the translation data is to be saved to.
This set of options only applies in a duplicated system. The options,
SPE_A
and
SPE_B,
refer to
processors
A
and
B
respectively in a duplicated system.
Invoking the command with the
active
option instructs the system to write to the specified device
in the active processor.
Invoking the command with the
standby
option instructs the system to write to the specified dev-
ice in the standby processor.
Invoking the command with the
either
option causes the system to write the translation data to
the specified device on both processors. If the standby processor is inaccessible, the command
will still execute on the active processor and data will be copied to the specified device.
Invoking the
save translation
command with the
SPE_A
option forces the system to write the
translation data to the specified device in processor A.
SPE_A
is the default in a simplex system.
Invoking the
save translation
command with the
SPE_B
option forces the system to write the
translation data to the specified device in processor B.
In duplicated systems,
both
is the default option.
The
[disk | tape]
option specifies the device on which to save the translation data. This option
set only applies in a system with a disk.
Invoking the
save translation
command with the
disk
option forces the system to write the
translation data to the disk. In a system configured with both a disk and a tape, disk is the
default.
Invoking the
save translation
command with the
tape
option forces the system to write the
translation data to the tape. In a system configured with only a tape unit, tape is the default.
In a duplex system, the capability to save translation to only one of the MSS devices is provided.
This capability should be exercised with extreme caution since it is Iikely to lead to translation
data inconsistencies between the different devices on the two processors.
