CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
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 Arguments
A 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 which may occur before or during command
execution. Within the command descriptions, error condition
notations may appear (E#, where # corresponds to the error
condition number). Refer to the “Error Conditions” section of
this chapter for explanations of the specific error conditions.
Save Announcement Command
The
save announcements
operation copies announcement data from the announcement board
(TN750) to the MSS. By default, announcement 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 announcements
command can be directed to write to devices on either of the
processors and/or to the secondary device(s).
Command Syntax
save announcements [active | standby | PE-A | PE-B | both | either] [disk | tape]
The bracketed options specify to which mass storage system the announcements are saved.
This set of options only applies in a duplicated system. The options,
active
and
standby,
refer to
the currently active and standby proccessors,
respectively, in a duplicated system. The options,
PE-A
and
PE-B,
refer to the processors in carriers
A and B, respectively, in a duplicated system.
Invoking the
save accouncements
command with the
active
option forces the system to write
the announcements data to the specified device in the currently active processor. In a simplex
system,
active
is the same as
PE-A
and is the default.
Invoking the
save announcements
command with the
standby
option forces the system to write
the announcements data to the specified device in the standby processor.
Invoking the
save announcements
command with the
PE-A
option forces the system to write
the announcements data to the specified device in processor A.
PE-A
is the default in a simplex
system.
Invoking the
save announcements
command with the
PE-B
option forces the system to write
the announcements data to the specified device in processor B.
8-2
Invoking the
save announcements
command with the both option forces the system to write the
announcements data to the specific device in both mass storage systems concurrently. If either
access fails, the entire operation fails. In a duplex system,
both
is the default.
