Chapter 13. Maintenance and Troubleshooting 

Draft Document for Review January 29, 2013 12:52 pm

The LEDs provide a general idea of the expansion canister status. You can obtain more detail 
from the management GUI and the Service Assistant. Examine the LEDs when you are not 
able to access the management GUI or the service assistant, or when the system is not 
showing any information about a device.

The CMM also shows status information about your expansion canisters, which you can use 
when the management GUI or the service assistant cannot be accessed. The CMM indicates 
the current status of many of the LEDs on your IBM Flex System V7000.

SASport 
activity

Green

��

OFF – Power is not present or there is no SAS link connectivity 
established. Check that the SAS cable is correctly connected at each 
end, and that the canisters it connects to are both powered on. The 
cable may need replacing.

��

ON SOLID – There is at least 1 active SAS link in the wide port 
established and there is no external port activity. This is a normal state 
and no action is required.

��

FLASHING – The expansion port activity LED should flash at a rate 
proportional to the level of SAS port interface activity as determined by 
the canister. The port also blinks when routing updates or configuration 
changes are being performed on the port. This is a normal state and 
no action is required.

Canister 
activity

Green

��

OFF – There is no host I/O activity.

��

FLASHING – The canister is actively processing input/output traffic 
(host I/O activity).

Fault

Amber

��

OFF – There are no isolated failures on the storage enclosure.

��

ON SOLID – There are one or more isolated failures in the storage 
enclosure requiring service or replacement. See the IBM Flex System 
V7000 Storage Node Troubleshooting, Recovery, and Maintenance 
Guide PDF on the CD for troubleshooting procedures.

Check log

Amber

��

OFF – There are no conditions that require the user to login to the 
management interface and review the error logs.

��

ON SOLID– The system requires the attention of the user via one of 
the management interfaces. There are multiple reasons that the Check 
Log LED could be illuminated.

control 
enclosure 
identify

Blue

��

OFF – There has been no request to identify the canister or enclosure.

��

ON SOLID – The canister or enclosure has been identified in request 
to user action.

��

BLINK – This occurs during power on and power-on self-test (POST) 
activities and when a command is being run from a USB flash drive
