configure sys-health-check auto-recovery
ExtremeWare Software 7.3.0 Command Reference Guide 653
I/O module faults are permanently recorded on the module’s EEPROM. A module that has failed a
system health check cannot be brought back online.
If the faulty module is a master MSM, the slave MSM automatically becomes the master and sets the
faulty MSM to
card-down
. 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 only
commands that do no affect the switch hardware configuration are allowed.
If the faulty module is a slave MSM, the fault is recorded in the slave’s MSM’s NVRAM and the slave
MSM is taken offline.
To view the failure messages, use the
show diag
command.
To clear the MSM failure messages posted to the log, use the
clear log diag-status
command. This
command will clear the error messages from the MSM NVRAM. If the MSM failed a system health
check, this command restores the MSM to full functionality. This command should only be used for
additional testing purposes and reproduction efforts of the original fault.
If you configure the system health check mode to
offline
and no new errors are detected, the device
scanned now remains online. This behavior is identical to the current behavior if you use the
run
diagnostics
command.
Example
The following command configures the system health checker to try ten times to bring a faulty MSM
back online:
configure sys-health-check auto-recovery 10
History
This command was first available in ExtremeWare 6.1.9.
The system health check functionality was modified in ExtremeWare 6.2.1 to support packet memory
defect detection and mapping on selected I/O modules.
This command was modified in ExtremeWare 6.2.2 to support system health check and checksum error
checking on the BlackDiamond 6804 switch and to add the
online
and
offline
parameters.
Platform Availability
This command is available on the BlackDiamond switch only.
The packet-memory defect detection and mapping feature is supported only on selected I/O modules.
See the release note for your version of ExtremeWare for information on the supported modules.
