It includes the following sections: • Overview, page 15-1 • Initial Troubleshooting Checklist, page 15-1 • Merge Failure Issues, page 15-4 • Validation and Commit Failure Issues, page 15-11 Overview When you configure different features for a Cisco MDS 9000 Family switch, such as zoning, DPVM, or port security, you must specify the correct device name each time. An inaccurate device name can cause unexpected results. You can circumvent this problem by defining and using device aliases. A device alias is a user-friendly name for a port WWN (pWWN) that can be used in all configuration commands as required. All switches in the Cisco MDS 9000 Family support Distributed Device Alias Services (device aliases). Initial Troubleshooting Checklist Device alias problems may result in merge, commit, or validation failures, and resolution requires gathering information about the specific failure and the fabric configuration. Begin troubleshooting device alias issues by checking the following items: Checklist Verify the device alias mode (basic or enhanced). Verify that device alias distribution is enabled. Verify that the fabric is not locked. Check off OL-9285-05 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x 15-1
