Objects | Measures | Measure Description | Possible Actions |
|---|---|---|---|
FC Port | CRC — CRC errors | The number of times an invalid cyclic redundancy check error occurs on a port or a frame that computes to an invalid CRC. Invalid CRCs can represent noise on the network. Such frames are recoverable by retransmission. Invalid CRCs can indicate a potential hardware problem. | • RAS Log Event • Port Decommission • Fence • SNMP Trap • E-mail • FICON Management Service |
ITW — Invalid transmit words | The number of times an invalid transmission word error occurs on a port. A word did not transmit successfully, resulting in encoding errors. Invalid word messages usually indicate a hardware problem. | ||
LOSS_SYNC — Loss of synchronization | The number of times a synchronization error occurs on the port. Two devices failed to communicate at the same speed. Synchronization errors are always accompanied by a link failure. Loss of synchronization errors frequently occurs due to a faulty SFP transceiver or cable. | ||
LF — Link failure | The number of times a link failure occurs on a port or the port sends or receives a Not Operational Sequence (NOS) state. Both physical and hardware problems can cause link failures. Link failures also frequently occur due to a loss of synchronization or a loss of signal. | ||
LOSS_SIGNAL — Signal loss | The number of times that a signal loss occurs in a port. Signal loss indicates that no data is moving through the port. A loss of signal usually indicates a hardware problem. | ||
PE — Protocol errors | The number of times a protocol error occurs on a port. Invalid state due to link reset response sequence (LRR) on an online link. Occasionally these errors occur due to software glitches. Persistent errors occur due to hardware problems. | ||
LR — Link reset | The ports on which the number of link resets exceed the specified threshold value. | ||
C3TXTO — Class 3 timeout | The number of class 3 frames discarded due to timeouts. | ||
STATE_CHG — State changes | The state of the port has changed for one of the following reasons: • The port has gone offline • The port has come online • The port is faulty | ||
DEV_NPIV_LOGINS — Device NPIV Logins | Monitors the number of logins on F_Ports in a switch. | ||
SFP | CURRENT — SFP transceiver current | The amount of supplied current to the SFP transceiver. Current area events indicate hardware failures. | • RAS Log Event • Port Decommission • Fence • SNMP Trap • E-mail • FICON Management Service |
RXP — SFP transceiver receive power | The amount of incoming laser, in microwatts (μw). This is used to help determine if the SFP transceiver is in good working condition. If the counter often exceeds the threshold, the SFP transceiver is deteriorating. | ||
TXP — SFP transceiver transmit power | The amount of outgoing laser, in microwatts (μw). This is used to help determine if the SFP transceiver is in good working condition. If the counter often exceeds the threshold, the SFP transceiver is deteriorating | ||
VOLTAGE — SFP transceiver voltage | The amount of voltage supplied to the SFP transceiver. If this value exceeds the threshold, the SFP transceiver is deteriorating. | ||
SFP_TEMP — SFP transceiver temperature | The physical temperature of the SFP transceiver, in degrees Celsius. A high temperature indicates that the SFP transceiver might be in danger of damage. | ||
PWR_HRS1 — SFP transceiver power on hours | The number of hours the 16Gb/s SFP transceiver is powered on. |
