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.
