FW-1219
Message
<Label>, is between high and low boundaries(High=<High value>, Low=<Low value>).
Current value is <Value> <Unit>.
Message Type
LOG
Severity
INFO
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, because only large numbers of messages indicate a problem in
this area.
Recommended
Action
No action is required. Respond to this message as is appropriate to the particular policy of the end-user
installation.
FW-1240
Message
<Label>, value has changed(High=<High value>, Low=<Low value>). Current value is
<Value> <Unit>.
Message Type
LOG
Severity
INFO
Probable Cause
Indicates that the number of end-to-end 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.
FW-1241
Message
<Label>, is below low boundary(High=<High value>, Low=<Low value>). Current value
is <Value> <Unit>.
Message Type
LOG
Severity
INFO
Probable Cause
Indicates that the number of end-to-end 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.
