FCR-1027 18 Recommended Action Severity 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 large number of 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 connectivity should be disabled then reenabled. INFO FCR-1027 Message , [FCR-1027], ,, INFO, , Port WWN roll over. Probable Cause Recommended Action Severity Indicates that the port WWN pool has rolled over and WWN entries detected to not be in use are reused as needed. 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 large number of 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 or VEX port connectivity should be disabled then re-enabled. INFO FCR-1028 Message , [FCR-1028], ,, INFO, , Node WWN pool 95 percent allocated. Probable Cause Recommended Action Severity Indicates that the node WWN pool is close to rollover and that the WWN entries detected to not be in use will be reused as needed. 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 large number of LSAN devices and fabrics, or there are highly dynamic changes to EX or VEX port connectivity.

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 large number of 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
connectivity should be disabled then reenabled.
Severity

Message
Probable
Cause
