Automatic Restart
Installing
There are two customer-provisionable parameters (SystemAutoRestartRate and
SystemAutoRestartDelay) and one new platform-provisionable parameter
(SystemAutoRestartNumSavedTraceLogs) for the BTS 10200 Automatic Restart feature. Additionally,
two existing parameters are expanded into three parameters.
Configuring
This section explains how to perform the following tasks:
•
•
Opticall Configuration
The configuration changes for this feature are the new customer-configurable parameters added to the
opticall.cfg file. These parameters are listed and discussed here. They are used to control the Automatic
Restart feature.
•
SystemAutoRestartRate—This variable indicates the number of times a platform auto restart is
attempted. This variable is defined to be the number of times a restart shall be attempted over a
30-minute interval.
•
SystemAutoRestartDelay—A side that is down should delay by this amount before attempting to
restart. The default is 10 minutes. The newly active side is allowed time to begin processing fully
before needing to support the auto restart of the faulty side by DB copies, etc.
Platform Configuration
The following parameter is added to the platform.cfg file.
•
SystemAutoRestartNumSavedTraceLogs—This variable indicates the number of most recent
consecutive trace logs to save.
The following parameters are changed in platform.cfg file. In earlier releases, the following parameters
could be set for each process.
•
SwitchOverIfMaxRestartExceededInDuplex = [yes | no]
•
EndPlatformIfMaxRestartExceededWhenMateFaulty = [yes | no]
To support the Automatic Restart feature, these two parameters are replaced with the following three
parameters.
•
ProcessCriticalFailureActionWhenMateStandby = [NONE | SDAMR | SDAAR | FISS]
•
ProcessCriticalFailureActionWhenMateActive = [NONE | SDAMR | SDAAR]
•
ProcessCriticalFailureActionWhenMateFaulty = [NONE | SDAMR | SDAAR]
These parameters allow different types of Automatic Restart shutdowns to be specified when a process
encounters a critical fault in Active, Standby, or Mate Faulty. For example, if the NIM (Node Interface
Monitor) encounters a critical fault in Active, a FISS could be specified, but if it encounters the fault in
Standby, an SDAAR could be specified.
FISS is not an option when the process is in a Standby state or a Mate Faulty state.
