Caveats Send documentation comments to [email protected] • CSCtb32209 Symptom: If there are DWDM link failures of less than 100ms, an MDS switch sends a NOS, which results in traffic disruption, especially when there is FICON traffic. Workaround: This issue is resolved • CSCsy52780 Symptom: Occasionally, when you enter the feature npv command to enable NPV, or enter the no feature npv command to disable NPV, the switch does not reload as expected. Instead, it returns to the Configuration mode prompt. Workaround: This issue is resolved. • CSCsy58106 Symptom: When dual supervisor modules are installed on a Cisco MDS switch running Cisco NX-OS Release 4.1(3a), if the feature fport_channel_trunk command has been issued to enable the F PortChannel feature and a switchover is performed, new F port trunking and F port channeling configurations cannot be made and the existing links may not come up if they flap after a switchover. Workaround: This issue is resolved. • CSCsz01738 Symptom: A host that is behind a NPIV F port cannot see the zoned LUNs if the addition of the F port to the zone and the zone set activation occur after an In Service Software Upgrade (ISSU). This issue applies only to an NPIV F port on MDS 9124 and MDS 9134 fabric switches Workaround: This issue is resolved. • CSCsz10089 Symptom: The IVR over FCIP MSM-18/4 license is not using the FCIP license, but is checking out the Enterprise license. Workaround: This issue is resolved. • CSCsz11613 Symptom: The otheridentifyingInfo property on the CIM Server is returning incorrect domain IDs. Workaround: This issue is resolved. • CSCsz16768 Symptom: When NPV is enabled, IP access list commands are not accessible. Workaround: This issue is resolved. • CSCsz40628 Symptom: An Inter-Switch Link (ISL) does not come up after one switch reloads. Workaround: This issue is resolved. • CSCsz74907 Symptom: In very rare circumstances, the zone server might fail due to a heartbeat failure. Workaround: This issue is resolved. • CSCsz75692 Symptom: When a Cisco Fabric Switch for HP c-Class BladeSystem or Cisco Fabric Switch for IBM BladeCenter reloads following the system startup-config init command, the switch does not auto boot, but remains at the loader prompt. The command erroneously erases the startup configuration from the boot flash. OL-19964-02 Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 4.2(1a) 43
