29 FW-1240 FW-1240 Message , [FW-1240], ,, INFO, , , value has changed(High=, Low=). Current value is . Probable Cause 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. 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-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 202 Fabric OS Message Reference 53-1000600-01

FW-1240
Message
<timestamp>, [FW-1240], <sequence-number>,, INFO, <system-name>, <Label>, value
has changed(High=<High value>, Low=<Low value>). Current value is <Value> <Unit>.
Probable Cause
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.
Recommended
Action
No action is required. Respond to this message as is appropriate to the particular policy of the
end-user installation.
Severity
INFO
FW-1241
Message
<timestamp>, [FW-1241], <sequence-number>,, INFO, <system-name>, <Label>, is
below low boundary(High=<High value>, Low=<Low value>). Current value is <Value>
<Unit>.
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
<timestamp>, [FW-1242], <sequence-number>,, WARNING, <system-name>, <Label>, is
above high boundary(High=<High value>, Low=<Low value>). Current value is <Value>
<Unit>.
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.
