■
SPE-Select Lead Change: (High or Critical Reliability system
only) The system could not determine why the SPE changed its
status from Active or Standby. However, this change usually
indicates a transition from Active to Standby. If a High or Critical
Reliability System does a PEI with a warm start, the system
software often requests a Cold 2 restart to recover properly only
minutes after the warm start has occurred.
■
SPE-Select Switch: (High or Critical Reliability system only) The
SPE-Select switches on the Duplication Interface circuit packs
were thrown to select the Standby SPE, which became the Active
SPE, using the restart level shown. It is also possible to get an
initialization cause of SPE-Select Switch when SPE B is active
and power to carrier B is lost. In this case, an SPE switch to SPE
A occurs and the initialization cause can show either SPE-Select
Switch or SPE Down. If this initcause triggers an
SPE-interchange when the Standby is NOT in Maintenance
mode, the previous entry in the log may actually represent a
restart that occurred on the Standby SPE. See the preceding
description of
‘‘display initcauses’’ for a complete explanation.
■
Stby-SPE Core Dump: (High or Critical Reliability system only)
The Standby SPE had finished a core dump when an interchange
took place that made the Standby SPE the Active SPE. If this
initcause triggers an SPE-interchange when the Standby is NOT
in Maintenance mode, the previous entry in the log may actually
represent a restart that occurred on the Standby SPE. See the
preceding description of
‘‘display initcauses’’ for a complete
explanation. If a High or Critical Reliability System does a PEI
with a warm start, the system software often requests a Cold 2
restart to recover properly only minutes after the warm start has
occurred.
■
Stby-SPE Tests: (High or Critical Reliability system only) The
Standby SPE was in the process of running tests at the request of
the Active SPE when an interchange occurred. If this initcause
triggers an SPE-interchange when the Standby is NOT in
Maintenance mode, the previous entry in the log may actually
represent a restart that occurred on the Standby SPE. See the
preceding description of
‘‘display initcauses’’ for a complete
explanation. If a High or Critical Reliability System does a PEI
with a warm start, the system software often requests a Cold 2
restart to recover properly only minutes after the warm start has
occurred.
■
Unknown: A restart that could not be classified. The Software
Error Log may contain more information about the restart.
■
Upgrade Software: (High or Critical Reliability system only) This
indicates that the system was upgraded to a new software
generic using the Standby SPE to load the new software via the
upgrade software command. A system technician-requested
reset system 4 command should be the previous entry.
