Reboot a node at the system prompt
You can reboot a node in normal mode from the system prompt. A node is configured to boot from the boot device, such as a PC CompactFlash card.
If the cluster contains four or more nodes, verify that the node to be rebooted does not hold epsilon:
Set the privilege level to advanced:
set -privilege advanced
Determine which node holds epsilon:
The following example shows that “node1” holds epsilon:
cluster1::*> cluster show Node Health Eligibility Epsilon -------------------- ------- ------------ ------------ node1 true true true node2 true true false node3 true true false node4 true true false 4 entries were displayed.
If the node to be rebooted holds epsilon, then remove epsilon from the node:
cluster modify -node node_name -epsilon false
Assign epsilon to a different node that will remain up:
cluster modify -node node_name -epsilon true
Return to the admin privilege level:
set -privilege admin
system node rebootcommand to reboot the node.
If you do not specify the
-skip-lif-migrationparameter, the command attempts to migrate data and cluster management LIFs synchronously to another node prior to the reboot. If the LIF migration fails or times out, the rebooting process is aborted, and ONTAP displays an error to indicate the LIF migration failure.
cluster1::> system node reboot -node node1 -reason "software upgrade"
The node begins the reboot process. The ONTAP login prompt appears, indicating that the reboot process is complete.
