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
It is unlikely that WWN conflicts will occur as a result of pool rollover unless the switch is deployed in a
Action 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.

Message
In slot <slot number>, node WWN pool 95 percent allocated.

Probable Cause

the WWN entries not detected to be in use will be reused as needed.
