35 FW-1241 Severity INFO FW-1241 Message , [FW-1241], ,, INFO, , , is below low boundary(High=, Low=). Current value is . Probable Cause Indicates that the number of end-to-end (EE) cyclic redundancy check (CRC) errors has fallen below the low boundary. 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 No action is required. Respond to this message as is appropriate to the particular policy of the end-user installation. A low number of CRC errors means that the fabric is functioning normally. The CRC error area of the End-to-End Performance Monitor class helps you tune your fabric. To reduce CRC messages, experiment with alternative topologies and cabling schemes. Severity INFO FW-1242 Message , [FW-1242], ,, WARNING, , , is above high boundary(High=, Low=). Current value is . Probable Cause Indicates that the number of end-to-end (EE) cyclic redundancy check (CRC) errors has risen above the high boundary. 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 The CRC error area of the end-to-end performance monitor class helps the user tune the fabric. To reduce CRC errors, experiment with alternative topologies and cabling schemes. Clean equipment, check temperatures, and replace old hardware. Severity WARNING FW-1243 Message Probable Cause , [FW-1243], ,, INFO, , , is between high and low boundaries(High=, Low=). Current value is . Indicates that the number of end-to-end (EE) cyclic redundancy check (CRC) errors has changed from a value outside of the acceptable range to a value within the acceptable range. 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. 254 Fabric OS Message Reference 53-1001157-01
