Color States
Amber OFF: There are no reported faults on the SAS link.
It is the normal state.
ON SOLID: There is no connectivity on the link.
SLOW BLINK: The port has been disabled and will not service
SAS traffic.
BLINK: One or more of the narrow ports of the wide SAS port link have
failed, the port is not operating at full capacity.
If the LED is not OFF, use the IBM Flex System V7000 management GUI,
if available, and use event log Fix Procedures to troubleshoot. These
procedures verify that the SAS cable is seated correctly at each end, it is
working, or if one of the canisters it connects to needs to be replaced.
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 might need replacing.
ON SOLID: There is at least 1 active SAS link in the wide port
established and there is no external port activity. It 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. It is a normal state and no
action is required.
Green OFF: There is no host I/O activity.
FLASHING: The canister is actively processing input/output traffic
(host I/O activity).
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.
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 by one of the
management interfaces. There are multiple reasons that the Check
Log LED could be illuminated.
