Channel Connection Failures
Host-to-array channel failures occur when the connection between the array and the
host is either severed or intermittent. The components that make up this data
channel connection are:
■
Host bus adapter (HBA), which resides on the host
■
GBIC adapter, used to connect the FC-AL cable to an SBus HBA
■
Fibre Channel cable that connects the array to the host
■
Channel interface port in the array
Errors in the host data channel are outside the scope of the array. To determine
failures in the data path, you must use host-based application diagnostics, such as
the StorTools product for the Solaris operating environment.
Refer to the documentation of the selected diagnostics tool for information on
identifying data channel failures.
FRU Failures
FRU failures are reported by an alarm or message notification from the tool used to
monitor the array. The failed FRU will most likely display a blinking amber LED.
Before replacing a FRU based on the LED indicator, verify its failure by using the
command-line interface (CLI) or the health-check mechanism in Sun StorEdge
Component Manager.
To check for a FRU failure using the CLI, refer to the Sun StorEdge T3+ Array
Administrator’s Manual. To use the Sun StorEdge Component Manager to diagnose a
failed FRU, refer to the Sun StorEdge Component Manager User’s Guide.
