Description
Power
(green)
Fault (amber)
System
status (green)
On Flashing Flashing fast
The Identify function for this canister has been activated.
The node is doing an emergency shutdown operation, using
the battery for power, after detecting a loss of power from
the power supply units.
Wait for the emergency shutdown operation to complete. If
the partner node has also done an emergency shutdown
operation, there was most likely a loss of input power to
both enclosure power supply units and the system restarts
when the input power is restored. Otherwise, there might be
a fault in the power supply units or the node canister.
On Flashing On
The Identify function for this canister was activated.
To determine if it is safe to remove the canister, use the
management GUI or service assistant to turn off the Identify
function, then check the node canister status LEDs, again.
On On Off
The Storwize V7000 Unified software is not running. The
BIOS might have detected a fault.
It is safe to remove or reseat the canister.
Try reseating the canister, as described in “Procedure:
Reseating a Storwize V7000 Gen2 node canister” on page 278.
If the canister still shows this fault, replace the node canister,
as described in “Replacing a Storwize V7000 Gen2 node
canister” on page 295.
On On Flashing
The node is in service state.
It is safe to remove or reseat the canister.
See Table 90 on page 261 to determine whether the battery
charge is insufficient.
Use the service assistant to identify any node errors or to
determine what to do, see “Procedure: Fixing node errors” on
page 271.
If the node is able to communicate with the configuration
node, there might also be an error alert in the system event
log, in which case you should run the associated fix
procedure.
On On Flashing fast
The node is in service state.
There is a code update in progress.
The canister must not be removed.
No action is required until the code update completes.
