42 FW-1218 Severity INFO FW-1218 Message , [FW-1218], ,, WARNING, , , is above high boundary(High=, Low=). Current value is . Probable Cause Indicates that the number of cyclic redundancy check (CRC) errors has risen above the high boundary. This indicates that errors have been detected in the FC frame. Invalid CRC messages occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and destination ID (D_ID) pairs change. These messages might also be caused by dirty equipment, temperature fluctuations, and aging equipment. Recommended Action You should configure a five- or six-figure high boundary for this area. Only five-figure (or higher) values for CRC errors indicate problems. When an "above" message is received, check for a faulty cable or deteriorated small form-factor pluggable (SFP). Replace the cable or SFP if necessary. Try cleaning the connectors. Check for damage from heat or deterioration from age. Severity WARNING FW-1219 Message , [FW-1219], ,, INFO, , , is between high and low boundaries(High=, Low=). Current value is . Probable Cause Indicates that the number of cyclic redundancy check (CRC) errors has changed from a value outside of the acceptable range to a value within the acceptable range. This indicates that errors have been detected in the FC frame. Invalid CRC messages occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and destination ID (D_ID) pairs change. These messages might also be caused by dirty equipment, temperature fluctuations, and aging equipment. You should set your high boundaries to five- or six-digit figures, as only large numbers of messages indicate a problem in this area. Recommended No action is required. Respond to this message as is appropriate to the particular policy of the Action end-user installation. Severity INFO FW-1240 Message Probable Cause , [FW-1240], ,, INFO, , , value has changed(High=, Low=). Current value is . Indicates that the number of end-to-end (EE) cyclic redundancy check (CRC) errors has changed. Invalid CRC messages occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and destination ID (D_ID) pairs change. These messages might also be caused by dirty equipment, temperature fluctuations, and aging equipment. Fabric OS Message Reference 309 53-1001338-01
