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
on page 76 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
)
If you enter the
cfgShow
command to display information about all zones, the TI zones appear in the defined zone configuration only
and do not appear in the effective zone configuration.
1.
Connect to the switch and log in as admin.
2.
Enter the
zone --show
command where
name
is the name of the zone to be displayed. If the name is omitted, the command
displays information about all TI zones in the defined configuration.
zone --show [name]
