314 Troubleshooting
Table 67 summarizes commands that are useful for debugging zoning issues.
Refer to ”Administering Advanced Zoning” on page 369 for additional information about setting up
zoning properly. Also refer to the Fabric OS Command Reference Manual for details about zoning
commands.
To correct a fabric merge problem quickly
You can correct zone conflicts by using the cfgClear command to clear the zoning database.
CAUTION: This is a disruptive procedure.
1. Determine which switch(es) have the incorrect zoning configuration; then, log in to the switches
as admin.
2. Enter the switchDisable command.
3. Enter the cfgDisable command.
4. Enter the cfgClear command.
CAUTION: This command clears the zoning database on the affected switches.
5. Enter the switchEnable command. This forces a zone merge and populates the switches with the
desired zoning database. The two fabrics will be merged again.
To correct a merge conflict without disrupting the fabric, first verify fabric merge problem, then edit
zone configuration members, and then reorder the zone member list.
To verify a fabric merge problem
1. Enter the switchShow command to validate that the segmentation is due to a zone issue.
2. Refer to Table 66 to view the different types of zone discrepancies.
