■ 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.
