FCR-1027 5 FCR-1027 Message In slot , 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 , node WWN pool 95 percent allocated.
