ExtremeWare 7.7 Command Reference Guide
Commands for Status Monitoring and Statistics
will indicate that it has been disabled by sending a message to the syslog. In ExtremeWare 6.2 or later,
this restriction does not apply.
If the faulty module is a master MSM, the slave MSM automatically becomes the master and sets the
faulty MSM to the card-down state. The new master MSM re-initializes and brings up all the I/O
modules.
If the faulty module is a master MSM and there is no slave MSM, the system continues operation in a
“limited commands” mode. In the “limited commands” mode, the I/O slots are not initialized, and the
only commands allowed are those that do not affect the switch hardware configuration.
If the faulty module is a slave MSM, the fault is recorded in the slave MSM NVRAM, and the slave
MSM is taken off line.
To view the status of the system health checker, use the
show diagnostics
command.
To enable the health checker, use the
enable sys-health-check
command.
To disable the health checker, use the
disable sys-health-check
command.
The alarm-level
system-down
option is especially useful in an ESRP configuration where the entire
system is backed by an identical system. By powering down the faulty system, you ensure that erratic
ESRP behavior in the faulty system does not affect ESRP performance and ensures full system failover
to the redundant system.
If you are using ESRP with ESRP diagnostic tracking enabled in your configuration, the system health
check failure will automatically reduce the ESRP priority of the system to the configured failover
priority. This allows the healthy standby system to take over ESRP and become responsible for
handling traffic.
To view the failure messages, use the
show diagnostics
command.
Example
The following command configures the system health checker response for MSMs such that a diagnostic
run is performed and the module is either shut down or reset, depending on the availability of the
remote MSM:
configure sys-health-check alarm-level msm auto-recovery
History
This command was first available in ExtremeWare 7.6.
