Canister fault
Color State
Amber OFF

ON
Meaning
The canister is
able to function
as an active
member of the
system. If there
is a problem on
the node
canister, it is not
severe enough to
stop the node
canister from
completing I/O
operations.
The canister is
being identified.
There might or
might not be a
fault condition.
The node is in
service state or
an error exists
that might be
stopping the
system code
from starting.
The node
canister cannot
become active in
the system until
the problem is
resolved. You
must determine
the cause of the
error before
replacing the
node canister.
The error may
be due to
insufficient
battery charge;
in this event,
resolving the
error simply
requires waiting
for the battery to
charge.
