Watchdog Timers - M1000e/M710
We have several M1000e chassis and several M710 blades. All of our M710 blades (latest firmware) are constantly alerting with watchdog timer expired alerts. The firmware on the chassis are up-to-date as well.
Is anyone else experiencing this?
Kendai21,
The Watchdog Timer Expired error is due to a lack of "heartbeat" response from the Watchdog Timer, which is used as a monitor for different internal components. When that heartbeat fails to arrive at the expected time/frequency then the error you are seeing appears. Normally the Watchdog Timer errors are accompanied by something else in the logs which identifies the actual cause error. Are you seeing anything else around the time that the Watchdog Timer error that looks suspicious?
Let me know what you see.
On each system the only log I see via the iDRAC is the watch dog timer expired . All other components of the system are green and I don't see any other errors. Just for additional info, these servers are running ESX 5.1.
My situtation is different (M600, not M710 and Windows 2008 R2, not ESX on the blade) but I see unanticipated watchdog timeout and ASR being asserted for no good reason. Seems like this is a hardware/firmware bug. :(

We just logged a ticket for our Equaliogic 6510 for a controller 'randomly' rebooting.
Turns out? Watchdog bug. 248 days and it reboots the controller.
The watchdog bug is pretty widespread across more than just Dell hardware too, Cisco has issues with watchdog on their ASR1000's as well.
