Fibre Channel Statistics and Definitions

The Fibre Channel Management–Statistic tab enables you to view statistics of the Fibre Channel ports on the Controller, including:

 

Property Name

Definition
Time Since Last Reset Time in minutes that the system has been ruinning
Number of Frames Sent Total number of frames sent since last reset
Number of Frames Received Total number of frames received since last reset
Number of Words Sent Total number of words sent since last reset
Number of Words Received Total number of frames received since last reset
LIP Count
 - Loop Initilization Primitive Sequence
This Primitive Sequence applies only to the Arbitrated Loop topology. It is transmitted by an LPort to (re)initialize the Loop
NOS Count
 - Not Operational Primitive Sequence
This Primitive Sequence is used during link initialization between two NPorts in the Point-to-point topology or an NPort and an FPort in the Fabric topology. It is sent to indicate that that transmitting port has detected a link failure or is offline. The expected response to a port sending NOS is the OLS Primitive Sequence.
Number of Error Frames FC devices propagate handshake signals back in forth requesting and acknowledging each byte transferred. FC transfers occur in frames of data on frame at a time. In this case this area reflects the number of Frames with errors.
Number of Dumped Frames This field specifies the dumped number of frames due to a lack of
host buffers.
Link Failure Count Amount of times the link has failed (literally pull the SFP or disconnect the link, can be caused by bad fiber element)
Loss Sync Count This field specifies the number of times loss of sync has
occurred.
Primitive Sequence Error Count 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 NPorts or an NPort and an FPort. LIP, LPB, and LPE are Primitive Sequences used in the Arbitrated Loop topology for initializing the Loop and enabling or disabling an LPort
Invalid Word Count This field specifies the number of invalid words received
Invalid CRC Count This field specifies the number of frames received with an invalid CRC.
Initiator IO Count I/O Count on the initiator on the host side
