    Duplicate IP address detected

      Nimble CS240

      Firmware v2.2.5.0

       

      Ever since we upgraded firmware to 2.2.5.0 (which was a real pain by the way) we started receiving "duplicate IP address detected" warnings on our CS240:

      -Subject: Nimble Alert on NIMBLEDR / NIMBLEDR (AA-######) - WARNING: Duplicate IP Address Detected

      The alerts happen once a day but never at the same time of day.

      We have not made any changes to the network configuration, no additional hardware was connected to the iSCSI switch (HP ProCurve 1800 with no CLI or logs unfortunately).

      The duplicate IPs listed in the alerts are the four ethernet interfaces on the Nimble which have not changed since initial setup two years ago.

       

      Does anyone have any suggestions? We are at a loss at this point. There does not seem to be any service interruption and support has not been able to find the root cause.

       

      Thank you.
