FW-1242
Recommended
No action is required. Respond to this message as is appropriate to the particular policy of the end-user
Action 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 the fabric. To reduce CRC messages,
experiment with alternative topologies and cabling schemes.
FW-1242
Message
<Label>, is above high boundary(High=<High value>, Low=<Low value>). Current value
is <Value> <Unit>.
Message Type
LOG
Severity
WARNING
Probable Cause
Indicates that the number of end-to-end 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
The CRC error area of the end-to-end performance monitor class helps you tune the fabric. To reduce
Action CRC errors, experiment with alternative topologies and cabling schemes. Clean equipment, check
temperatures, and replace old hardware.
FW-1243
Message
<Label>, is between high and low boundaries(High=<High value>, Low=<Low value>).
Current value is <Value> <Unit>.

INFO
Probable Cause
Indicates that the number of end-to-end 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.
