Zone Issues Chapter 8 This chapter describes troubleshooting techniques and recommended actions for common zoning problems. In this chapter •Overview of corrective action 63 •Segmented fabrics 63 •Zone conflicts 64 •Gathering additional information 68 Overview of corrective action The following overview provides a basic starting point for you to troubleshoot your zoning problem. 1. Verify that you have a zone problem. 2. Determine the nature of the zone conflict. 3. Take the appropriate steps to correct zone conflict. To correct a merge conflict without disrupting the fabric, first verify that it was a fabric merge problem, then edit zone configuration members, and then reorder the zone member list if necessary. The newly changed zone configuration will not be effective until you issue the cfgEnable command. This should be done during a maintenance window because this may cause disruption in large fabrics. Verifying a fabric merge problem 1. Enter the switchShow command to validate that the segmentation is due to a zone issue. 2. Review "Segmented fabrics," next, to view the different types of zone discrepancies and determine what might be causing the conflict. Segmented fabrics This section discusses fabric segmentation. Fabric segmentation occurs when two or more switches are joined together by ISLs and do not communicate to each other. Each switch appears as a separate fabric when you use the fabricShow command.
