■ Enables shadowing from Active SPE Memory to Standby SPE Memory and
causes all of Active SPE Memory to be written to Standby SPE Memory (a
refresh operation).
■ Disables shadowing from Active SPE Memory to Standby SPE Memory.
■ Requests the Standby SPE Maintenance/Tape Processor to release the
Standby SPE Processor for the Standby SPE Processor to perform a RAM
checksum test on Standby SPE Memory (just updated by the refresh
operation).
■ Waits for Standby SPE Processor to report the results of the RAM
checksum test.
■ Requests the Standby SPE Maintenance/Tape Processor to hold the
Standby SPE Processor reset.
■ Enables shadowing from Active SPE Memory to Standby SPE Memory and
causes all of Active SPE Memory to be written to Standby SPE Memory (a
refresh operation).
Flash-based systems
■ Disables shadowing from Active SPE Memory (MEM-BD) to Standby SPE
Memory.
■ Requests the Standby SPE Maintenance/Tape Processor (PR-MAINT) to
release the Standby SPE processor (PROCR) for the Standby SPE
Processor to clear a magic area in Standby SPE Memory.
■ Requests the Standby SPE Maintenance/Tape Processor to hold the
Standby SPE processor reset.
■ Enables shadowing from Active SPE Memory to Standby SPE Memory and
causes all of Active SPE Memory to be written to Standby SPE Memory (a
refresh operation).
■ Disables shadowing from Active SPE Memory to Standby SPE Memory.
■ Requests the Standby SPE Maintenance/Tape Processor to release the
Standby SPE Processor for the Standby SPE Processor to perform a
verification on the magic area in Standby SPE Memory (just updated by the
refresh operation).
■ Requests the Standby SPE Maintenance/Tape Processor to hold the
Standby SPE Processor reset.
■ Enables shadowing from Active SPE Memory to Standby SPE Memory and
causes all of Active SPE Memory to be written to Standby SPE Memory (a
refresh operation).
NOTE:
The shadowing verification method used for 80386 systems does not
do a complete RAM checksum. It only clears a special magic area in
the Standby SPE’s memory and then updates that area by
shadowing. It then verifies the value in that magic area based on the
