As a result, hosts to not appear in the Step 1 window of the the Fabric Manager DMM job creation wizard. Workaround: Restart the Fabric Manager Server. • CSCsk35725 Symptom: Fabric Manager takes 2 to 3 minutes to bring up the DMM job creation wizard in a setup with 25 switches, 400 enclosures, and 2400 entries in the name server. Workaround: None. • CSCsk35951 Symptom: In a configuration with a PortChannel with FCIP members and Write Acceleration in use, if IVR NAT is enabled on one end of the PortChannel and not enabled on the other end, then traffic over the FCIP tunnel might fail. Workaround: Enable IVR NAT on both ends of the PortChannel or disable it on both ends. • CSCsk39341 Symptom: Although the FCIP compression ratio is set to Auto, it does not display correctly in Fabric Manager Server.
