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 are not 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 because of a zone issue.
2. Review “Segmented fabrics,” to view the different types of zone discrepancies and determine
what might be causing the conflict.
Verifying a TI zone problem
Use the zone -- show command to display information about TI zones. This command displays the
following information for each zone:
• Zone name
• E_Port members
• N_Port members
• Configured status (the latest status, which may or may not have been activated by cfgEnable)
• Enabled status (the status that has been activated by cfgEnable)
