25 FW-1242 Probable Cause Recommended Action Severity Indicates that the number of EE 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. 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. INFO FW-1242 Message , [FW-1242], ,, WARNING, , , is above high boundary(High=, Low=). Current value is .

Probable Cause Recommended Action Severity Indicates that the number of EE 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. No action is required.

Fabric OS Message Reference
Publication Number: 53-1000242-01
FW-1242
25
Probable
Cause
Indicates that the number of EE 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.
