FW-1242
30
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.
Severity WARNING
FW-1243
Message <timestamp>, [FW-1243], <sequence-number>,, INFO, <system-name>, <Label>, is
between high and low boundaries(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
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.
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-1244
Message <timestamp>, [FW-1244], <sequence-number>,, INFO, <system-name>, <Label>, value
has changed(High=<High value>, Low=<Low value>). Current value is <Value> <Unit>.
