Access 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.
Both the SP and 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.

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 ONTAP. Ctrl-D is then pressed to exit the console and return to the SP.
