System status
LED
Fault LED Status Action
On Off Code is active.
Node state is
active.
No action. The node canister is part of
a clustered system and can be managed
by the management GUI.
On On Code is active
and is in starting
state. However, it
does not have
enough resources
to form the
clustered system.
The node canister cannot become active
in a clustered system. There are no
detected problems on the node canister
itself. However, it cannot connect to
enough resources to safely form a
clustered system. Follow the procedure
to fix the node errors. Go to
“Procedure: Fixing node errors” on
page 204.
Flashing Off Code is active.
Node state is
candidate.
Create a clustered system on the node
canister, or add the node canister to the
clustered system. If the other node
canister in the enclosure is in active
state, it automatically adds this node
canister into the clustered system. A
node canister in this state can be
managed using the service assistant.
Flashing On Code is active.
Node state is
service.
The node canister cannot become active
in a clustered system. Several problems
can exist: hardware problem, a problem
with the environment or its location, or
problems with the code or data on the
canister. Follow the procedure to fix the
node errors. Go to “Procedure: Fixing
node errors” on page 204.
Any Flashing The node canister
is being
identified so that
you can locate it.
The fix procedures in the management
GUI might have identified the
component because it requires
servicing. Continue to follow the fix
procedures. The service assistant has a
function to identify node canisters. If
the identification LED is on in error,
use the service assistant node actions to
turn off the LED.
