configure sys-recovery-level
configure sys-recovery-level [none | [all | critical] [msm-failover |
reboot | shutdown | system-dump [maintenance-mode | msm-failover | reboot |
shutdown]]]
Description
Configures a recovery option for instances where an exception occurs in ExtremeWare.
Syntax Description
Default
None.
Usage Guidelines
This command is used for system troubleshooting. If the system fails before the switch is booted up, the
switch will automatically start the console and allow access to the system to view the logs or debug the
failure. You can also configure the system to respond to software failures automatically. You must
specify one of the following parameters for the system to respond to software failures:
•
none
—No action is taken when a task exception occurs.
•
all
—The system will reboot or shut down if any task exception occurs.
•
critical
—The system will reboot or shutdown if a critical task exception occurs. Critical tasks
include the tBGTask, tNetTask, tEdpTask, and tESRPTask.
For ExtremeWare 6.1, the system will always reboot after a task exception when the system recovery
level is specified as
all
or
critical
.
For ExtremeWare 6.2 or later, you must specify whether the system should shut down or reboot upon a
task exception if the recovery level is
all
or
critical
.
none Configures the level to no recovery. No action is taken when a task exception
occurs; there is no system shutdown or reboot.
all Configures ExtremeWare to log an error into the syslog and either shutdown
or reboot the system after any task exception occurs.
critical Configures ExtremeWare to log an error into the syslog and either shutdown
or reboot the system after a critical task exception.
msm-failover Triggers the slave MSM to take over control of the switch if there is a software
exception on the master MSM. BlackDiamond switches only.
reboot Reboots the switch.
shutdown Shuts down the switch.
system-dump Triggers a dump transfer, followed by the specified completion action (reboot,
shutdown, msm-failover, or maintenance-mode). Maintenance mode leaves
the switch in whatever state the dump transfer puts it in. Some subsystems
may no longer behave correctly or operate at all after a system dump. The
system-dump option should only be used with assistance from TAC. Available
on switches with Ethernet management ports only.
