No action is required. Respond to this message as is appropriate to the particular policy of the
end-user installation.
Severity INFO
FW-1218
Message <timestamp>, [FW-1218], <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 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 <timestamp>, [FW-1219], <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 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.
