Monitoring and Managing the Director
There are no thresholds for this value. Typically, this occurs when
the destination is not available due to the destination device’s
action.
◆
Four Byte Words Rx
— The number of four-byte words received.
◆
Four Byte Words Tx
— The number of four-byte words
transmitted.
Error Statistics
Error statistics show whether or not a port is operating correctly. Use
this data to isolate problems with port and link operations:
◆
Link failures
— The number of link failures. A link failure is
recorded in response to a not operational sequence (NOS),
protocol timeout, or port failure. A yellow triangle appears in the
Hardware view to indicate a link incident. A blinking red and
yellow diamond appears to indicate a port failure.
◆
Sync losses
— The number of loss-of-synchronization errors,
which occur if the attached device is reset or disconnected from
the port. A yellow triangle appears in the Hardware view to
indicate a link incident.
◆
Signal losses
— The number of loss-of-signal errors, which occur
if the attached device is reset or disconnected from the port. A
yellow triangle appears in the Hardware view to indicate a link
incident.
◆
Primitive sequence errors
— The number of primitive sequence
protocol errors. A yellow triangle appears in the Hardware view
to indicate a link incident.
◆
Discarded frames
— The total number of frames discarded. A
received frame cannot be routed and is discarded if the frame
times out (insufficient buffer-to-buffer credit) or the destination
device is not logged in to the director.
◆
Invalid transmission words
— The number of times that the
director detected invalid transmission words from the attached
device. This indicates that a frame or primitive sequence arrived
at the director’s port corrupted. This corruption can be due to the
attached device performing a reset, plugging or unplugging the
link, bad optics at either end of the cable, bad cable, or a dirty or
poor connection. Moving the connection around or replacing
cables can isolate the problem.
Some number of invalid transmission words are expected and
acceptable. Invalid transmission words within a frame are used to
produce the bit-error threshold link incident. If one or more
