Node canister status LED statues

3. If the power LED is on solid, consider the states of the fault LEDs 3 and 4 for each node 

canister, as shown in Table 13-4

4. If the canister fault LED and the internal fault LED do not indicate a problem, consider the 

state of the battery LEDs 5, 6, and 7, as shown in Table 13-5 on page 528 on each node 
canister. The canister will not run as part of the IBM Flex System V7000 unless it is sure it 
can save its state and cache data in the event of power loss to the canister. See 
Understanding the battery operation for the node canister. 

Canister status

Green

��

OFF – The IBM Flex System V7000 system code is not running. If the 
Power LED is ON, the operating system has not started the IBM Flex 
System V7000 system code yet. This state is normal just after the 
canister is powered on. If it persists for more than 10 minutes, check 
the canister status using the CMM. 

��

ON SOLID – The canister is active and able to perform I/O as part of a 
IBM Flex System V7000. The IBM Flex System V7000 management 
GUI is available if any node canister in the system has its status LED 
ON. Do not power off, or remove, a node canister whose status LED is 
on solid. You might lose access to data or corrupt volume data. Follow 
the proper procedure to shut down a node so that access to data is not 
compromised.

��

BLINK – The canister is in candidate or service state and is not 
participating in I/O. If possible, use the recommended action in the 
event log event log shown by the management GUI to service the node 
canister. If this is not possible, use the service assistant to determine 
the state of the node canister and resolve any critical node errors that 
stop the canister from becoming active.

Canister fault

Amber

��

OFF – The node canister is operating correctly, or it has not been 
possible to isolate an issue to the node canister.

��

ON SOLID – The node canister has failed and should be replaced. If it 
is available, use the IBM Flex System V7000 management GUI event 
log fix procedures to guide the replacement.

Internal fault

Amber

There is a fault on one or more of the replaceable parts in the canister, it 
has been determined that the part needs replacing.
Note: This LED only applies to the network adapters. (There may be one or 
two of them.) Review the IBM Flex System V7000 Storage Node event logs 
or the CMM to identify the network adapter that failed.

��

OFF – There are no failures isolated to internal components of the 
canister

��

ON SOLID – Replace the failing network adapter
