  • 1.  Aruba controller reboot

    Posted Feb 27, 2018 08:47 AM

    Hi,

    I have Aruba controllers 7010 (version 6.5.4.3) that gets rebooted (wlsxColdStart Detected),

    From the Webgui, the logs show that the controller was down and back up,

    From CLI, I noticed that the logs were showing (killing dogma and watchdog) before and after the reboot,

    It doesn't really say what caused the reboot,

    Is there some other ways to find out what cause the reboot?

    thanks

    JF

    Is there a crash.tar file? We are having the same problem and TAC is
    looking into it but we never get a crash.tar file

    I ran the command (show switchinfo) from the CLI and I got the result below.

    No crash information avalaible.

    Reboot cause: Power Cycle

    Is the controller connected to a UPS? Did anything else connected to the same device go down?

     

    ColdStart makes me think it lost power. WarmStart usually indicates a reboot initiated by command.

    no, there is no UPS connected on that one.

    It seemed that there was a lost of power that caused this

    I would see if you can check a switch or something in the same rack or connected to a close outlet. Check the uptime and see if anything else went down.

     

    There is a known bug in AOS 6.5.4.3 that causes controller to reboot, but the reason is different, so I don't suspect that to be the issue.

    Do you have more information on the known bug in AOS 6.5.4.3?

    Bug id : 167418

     

    Symptom: A master controller rebooted after DPI was disabled. The log file listed the reason for the event as Reboot Cause: Datapath timeout (SOS Assert) (Intent:cause:register 54:86:50:2). The fix ensures that the controller works as expected.

    Scenario: This issue was observed in controllers running ArubaOS 6.5.3.1.

    There's quite a lot of resolved issues in the latest ArubaOS 6.5.4.x release which related to a unexpected reboot due to various reasons. Some of these appear to be written to the log file. The log file won't survive a reboot, do you have a syslog server you could set up in order to capture some logs?
