Mode or whether it is in Maintenance Mode. Whenever this command is
issued, any Standby SPE maintenance activity currently in progress
(except for entering maintenance mode) is preempted, the Standby SPE
Processor is held reset, and the Standby SPE’s memory is refreshed.
Recall that the refresh is necessary because, while the Standby SPE is in
Maintenance Mode, memory shadowing is disabled. When the Standby
SPE is returned to Standby Mode, its memory must be brought up-to-date
with Active SPE memory.
Because they can preempt Standby SPE maintenance activities, the
refresh spe-standby and busyout spe-standby commands should be
used judiciously. If the Standby SPE is in Maintenance Mode when one of
these commands is issued, the current maintenance activity being
conducted by the Standby SPE is immediately terminated with the
following potential side-effects:
■ Testing of the Standby SPE components that are the target of the
maintenance activity may not have completed. Depending on the
maintenance activity and the point at which such activity is
terminated, tests that detect faults and/or lack of faults on those
Standby SPE components may not have had the opportunity to run.
Accordingly, alarms will not be raised or retired on the components.
■ If the maintenance activity is Scheduled Maintenance, and if the
refresh spe-standby or busyout spe-standby command is issued
before a scheduled translation save is performed, the translation
save is not completed, and the translation data on both the Active
SPE and Standby SPE and on the memory cards do not reflect the
changes made since the last translation save.
In general, after a refresh spe-standby has been used, and after the user
has finished working with the system, the test spe-standby long
command should be issued in the event that the refresh spe-standby
command preempted a Standby SPE maintenance activity. Testing the
standby SPE allows standby maintenance to re-determine the health of the
standby SPE and to compare this health to that of the active SPE. This
testing could result in an SPE interchange to a healthier SPE.
If the busyout spe-standby command has been used, the release
spe-standby command should also be used. The latter command fully
tests the standby SPE 1 minute later.
Also, if the refresh spe-standby or busyout spe-standby command was
used within the time frame that scheduled maintenance with a translation
save was to have been conducted, the save translation command should
be issued to ensure that the current translation data has been written to
the Active SPE and Standby SPE tapes.
When using the refresh spe-standby to preempt Standby SPE
maintenance activities, it may be necessary to issue the refresh
spe-standby command multiple times in order to preempt all Standby
SPE maintenance activity. If the refresh spe-standby command
successfully completes five times without the Standby SPE becoming
