Search the log messages between the two log messages for a log message like
Batch backup

If no log message like the specified message is found, the original standby MPU was
starting up when you executed the
reboot
command. No action is required. Next time you
want to use the
reboot
slo
t command to reboot the active MPU, make sure the standby
MPU has started up.
If a log message like the specified message is found, contact H3C Support.
Exceptional active/standby MPU switchover
Symptom
While the device is operating correctly, the active MPU reboots and the standby MPU becomes the
new active MPU.
Solution
To resolve the problem:
1.
In probe view, use the
display hardware internal util slot
slot-num rbinfo
5
detail
command
to display reboot records.
2.
If the most recent record is
slave-rob
, the standby MPU became the new active MPU because
it did not receive packets from the original active MPU. Wait for the original active MPU to start
up and then contact H3C Support.
3.
If no
slave-rob
record is found, an exception occurred on the original active MPU. Execute the
following commands to collect diagnostic information and then contact H3C Support:
d
isplay hardware internal util slot
slot-num rbinfo

display kernel exception
