System Backup
System translations can be restored by using the data on the system or on the
backup translation card if the length of power failure is appropriate for the
corresponding system. Table 5-1
lists the requirements:
Save Translation
To ensure that the translation card contains the most recent copy of the
translation data, the system can automatically save the translation data onto the
translation card every 24 hours. Automatic daily backup of the system translation
data is controlled by an entry in the system parameters that defaults to "daily".
If many translation data changes are made, it is recommended that you save the
translation data using the save translation command. This action saves the new
changes to the translation card without having to wait for the next automatic daily
translation backup.
NOTE:
The save translation command blocks all maintenance commands except
some list, display, monitor, and status commands.
The system blocks the execution of any commands that change translations or
trigger a maintenance action (for example, test board, busyout port, and so
forth). The status card-mem command is blocked during the save translation
operation.
In a high or critical reliability system, if the save translation command is entered
without a qualifier, an attempt is made to save the translations on
both
the Active
and Standby SPE. If the command is qualified with either "spe-active" or
"spe-standby," the translations are saved only on the specified SPE. For example,
if, when the save translation command was issued, the translations were
successfully saved on the active SPE’s translation card, but were not
successfully saved on the standby SPE’s translation card, issue the save
translation spe-standby command to save the translations on the standby SPE
as well.
