Caveats Send documentation comments to [email protected] Symptom: A Cisco MDS 9000 switch does not respond to an FDISC request from an attached switch with NPV enabled if the MDS 9000 switch is already processing an FDISC request for the same pWWN. This symptom might be seen if the downstream device has NPV mode enabled, and the MDS 9000 switch is processing an FDISC request for the same pWWN and no ABTS request is sent to cancel the in-progress FDISC request. Workaround: This issue is resolved. • CSCtd04154 Symptom: The DMM CPP interface cpp1/1/1 does not come up unless there is an active port in VSAN 1, which is the DMM management VSAN. This symptom might be seen when an interface is either not defined or is not up in VSAN 1. Workaround: This issue is resolved. • CSCti38286 Symptom: When you create a DMM job, DMM might intermittently display the following message: DMM_JOB_INFRA_FC_REDIRECT_SETUP_ERR. This symptom might be seen when there are two or more paths to a host, multiple paths to existing storage, and multiple paths to the new storage. Workaround: This issue is resolved. • CSCtj84690 Symptom: When you upgrade from Cisco NX-OS Release 4.1(3a) to NX-OS Release 5.0(1a), certain ports are brought down because of diagnostics failure.
