    No coredump target has been configured

    WebOps Novice

      Hi

       

      I'm seeing the "No coredump target has been configured" message on one of my hosts after installation and it has local storage. I should have fixed this before it has VM's on it but I didn't..

       

      So I check to see what it is currently set at...

       

      C:\Program Files (x86)\VMware\VMware vSphere CLI>esxcli -s X.X.X.X  -h Y.Y.Y.Y system coredump partition get

      Enter username: XXXXXXX

      Enter password:

      Not a known device: naa.6d4ae520a0be19001b76325c0ec1d22a

       

      Then I list available partitions

       

      C:\Program Files (x86)\VMware\VMware vSphere CLI>esxcli -s X.X.X.X  -h Y.Y.Y.Y system coredump partition list

      Enter username: XXXXXXX

      Enter password:

      no configured dump partition found; skipping

       

      My concern is accidentally initialising an active partition, how can I set the coredump partition and can it be done via the web client?

          Hi,

           

          Please check out this KB :

           

          VMware KB: Configuring a diagnostic coredump partition on an ESXi 5.x host

           

          1. Validate that something shows up in this list -  esxcli system coredump partition list

          2. Set the coredump partition by :

            esxcli system coredump partition set --partition="mpx.vmhba2:C0:T0:L0:7"

            esxcli system coredump partition set --enable true

           

          You can also try using :

          esxcli system coredump partition set --enable true --smart

          This will automatically set a partition.

           

          Hope this helps.

            Solución al problema "no coredump target has been configured. host core dumps cannot be saved"

             

            Mediante SSH, consultamos el estado de la partición de diagnostico (coredump).

            # esxcli system coredump partition get

            Not a known device *mi-anterior-identificador-de-disco*

            # esxcli system coredump partition list

            no configured dump partition found; skipping

             

            El resultado muestra que esto no está funcionando, si es el caso, se necesita re-configurar la partición de diagnóstico.

            # esxcli system coredump partition set --unconfigure

             

            Listamos las particiones existentes

            # esxcli system coredump partition list

            Name Path Active Configured

            -------------------------------------- ---------------------------------------------------------- ------ ----------

            naa.6005076040ab4c101d8314b335edd7a0:7 /vmfs/devices/disks/naa.6005076040ab4c101d8314b335edd7a0:7 false false

            naa.6005076040ab4c101d8314b335edd7a0:9 /vmfs/devices/disks/naa.6005076040ab4c101d8314b335edd7a0:9 false false

            Para seleccionar y activar automáticamente una partición de diagnóstico accesible, ejecutamos el siguiente comando:

            # esxcli system coredump partition set --enable true --smart

             

            Nuevamente consultamos el estado de la partición de diagnóstico y listo, problema resuelto.

            # esxcli system coredump partition get

            Active: naa.6005076040ab4c101d8314b335edd7a0:9

            Configured: naa.6005076040ab4c101d8314b335edd7a0:9

              Even if I don't understand spanish, I understood the command in Tyepez post and this was the solution for us after migration the boot into a new SAN we had these error on all our esxi host. Thank you for this information.

                  i am having issue because new ESXi hosts is storing its coredump file on different data stroe on SAN and some ESXi stroing on local disk.

                  i am trying to find out how ESXi pick to SAN (VNX)datastroe or local datastore to store its coredump file.

                    we did not configured coredump target when we setup new ESXi6.5 hosts
