Note: Because these components are inside the node canister, their replacement leads to
a redundancy loss until the replacement is complete.

State and Meaning
OFF The node is in candidate or active state. Any error that has been
detected is not severe enough to stop the node participating in a cluster or
performing I/O.
BLINK The canister is being identified. There might or might not be a fault
condition.
ON The node is in service state or an error exists that might be stopping the
system code from starting (node error 550). The node canister cannot
become active in the system until the problem is resolved. The problem is
not necessarily related to a hardware component.
