Instructions

To configure ESXi to generate the Coredump as a file on a Virtual Machine File System (VMFS): 

  1. Connect to the ESXi host using the SSH.
  2. Run this command to add a new file, used as a Coredump: 
    esxcli system coredump file add
    -d can be used to specify the VMFS datastore used for the Coredump file. If it is not provided, a datastore of sufficient size is automatically selected.
    -f can be used to specify a file name for the Coredump file. If it is not provided, a unique name is created.

    For Example:
    esxcli system coredump file add -d VMFS_VOLUME -f test   
  3. Run this command to get the list of all dump files:
    esxcli system coredump file list

    Output similar to the following appears:
    Path                                                                     Active Configured Size
    ------------------------------------------------------------------------ ------ ---------- ---------
    /vmfs/volumes/52b021c3-f6b3da50-4c76-001d0904c5a5/vmkdump/test.dumpfile  false  false      104857600

    If no Coredump file is specified, no output displays from running the command.
       
  4. Run this command to set the dump file for the host:
    esxcli system coredump file set -p /vmfs/volumes/DATASTORE_UUID/vmkdump/FILENAME 

    For Example:
    esxcli system coredump file set -p /vmfs/volumes/52b021c3-f6b3da50-4c76-001d0904c5a5/vmkdump/test.dumpfile
     
  5. Run this command to verify that the dump file is active and configured:
    esxcli system coredump file list

    Output similar to the following appears:
    Path                                                                     Active Configured Size
    ------------------------------------------------------------------------ ------ ---------- ---------
    /vmfs/volumes/52b021c3-f6b3da50-4c76-001d0904c5a5/vmkdump/test.dumpfile  True   True                    104857600


    The output indicates that the active and configured status of the file is True.
