Definitions of the properties for which statistical information is reported appears in the list below.
•
TimeLastReset
– Time in minutes since the system has been running.
•
FramesSent
– Number of frames sent since last reset.
•
FramesReceived
– Number of frames received since last reset.
•
WordsSent
– Number of words sent since last reset.
•
WordsReceived
– Number of words received since last reset.
•
LIPCount
– Loop Initialization Primitive Sequence. This primitive sequence applies only to the arbitrated
loop topology. It is transmitted by an L_Port to initialize or re-initialize the loop.
•
NOSCount
– Not Operational Primitive Sequence. This primitive sequence is used during link initialization
between two N_Ports in the point-to-point topology or an N_Port and an F_Port in the fabric topology.
NOS is sent to indicate that the transmitting port has detected a link failure or is offline. The expected
response to a port sending NOS is the OLS primitive sequence.
•
ErrorFrames
– FC devices propagate handshake signals back-and-forth requesting and acknowledging
each byte transferred. FC transfers occur in one frame of data at a time. In this case, the value reflects the
number of frames with errors.
•
DumpedFrames
– This field specifies the number of frames dumped due to a lack of host buffers.
•
LinkFailureCount
– Number of times the link has failed. Can be caused by a disconnected link or a bad
fiber element.
•
LossSyncCount
– Number of times a loss of sync has occurred since last reset.
•
PrimitiveSeqErrorCount
– An ordered set transmitted repeatedly and used to establish and maintain a link.
LR, LRR, NOS, and OLS are primitive sequences used to establish an active link in a connection between
two N_Ports or an N_Port and an F_Port.
LIP, LPB, and LPE are primitive sequences used in the Arbitrated Loop topology for initializing the loop
and enabling or disabling an L_Port.
•
InvalidWordSentCount
– Number of invalid words sent since last reset.
•
InvalidCRCCount
– Invalid Cyclical Redundancy Count. Number of frames received with an invalid CRC
since last reset.
•
InitiatorIOCount
– I/O Count on the initiator on the host side.
