Accessing the system console of a node

If a node is hanging at the boot menu or the boot environment prompt, you can access it only through the system console (also called the serial console). You can access the system console of a node from an SSH connection to the node's SP or to the cluster.

About this task

Both the SP and Data ONTAP offer commands that enable you to access the system console. However, from the SP, you can access only the system console of its own node. From the cluster, you can access the system console of any node in the cluster.

Steps

  1. Access the system console of a node:
    If you are in the... Enter this command...
    SP CLI of the node system console
    Data ONTAP CLI system node run-console
  2. Log in to the system console when you are prompted to do so.
  3. To exit the system console, press Ctrl-D.

Examples of accessing the system console

The following example shows the result of entering the system console command at the "SP node2" prompt. The system console indicates that node2 is hanging at the boot environment prompt. The boot_ontap command is entered at the console to boot the node to Data ONTAP. Ctrl-D is then pressed to exit the console and return to the SP.

SP node2> system console
Type Ctrl-D to exit.

The following example shows the result of entering the system node run-console command from Data ONTAP to access the system console of node2, which is hanging at the boot environment prompt. The boot_ontap command is entered at the console to boot node2 to Data ONTAP. Ctrl-D is then pressed to exit the console and return to Data ONTAP.
