FCR-1027
Message In slot <slot number>, Port WWN roll over.
Message Type LOG
Severity INFO
Probable Cause Indicates that the port World Wide Name (WWN) pool has rolled over in the specified slot, and WWN
entries not detected to be in use are reused as needed.
Recommended
Action
It is unlikely that WWN conflicts will occur as a result of pool rollover unless the switch is deployed in a
very large MetaSAN environment with a large number of logical storage area network (LSAN) devices
and fabrics, or there are highly dynamic changes to EX_Port connectivity. WWN conflicts might cause
unpredictable behavior in management applications. To avoid WWN conflicts, all EX_Ports attached to
fabrics with highly dynamic changes to EX_Port or VEX_Port connectivity should be disabled and then
re-enabled.
FCR-1028
Message In slot <slot number>, node WWN pool 95 percent allocated.
Message Type LOG
Severity INFO
Probable Cause Indicates that the node World Wide Name (WWN) pool is close to rollover in the specified slot, and that
the WWN entries not detected to be in use will be reused as needed.
