Zone conflicts
9
Symptom Zone conflict appears in logs and fabric is segmented.
Probable cause and recommended action
This issue is usually caused by incompatible zoning configurations. Verify the following are true:
• The effective cfg (zone set) on each end of the segmented ISL is identical.
• Any zone object with the same name has the same entries in the same sequence.
Symptom Fabric segmentation is caused by a “configuration mismatch”.
Probable cause and recommended action
Occurs when zoning is enabled in both fabrics and the zone configurations are different in each
fabric.
Symptom Fabric segmentation is caused by a “type mismatch”.
Probable cause and recommended action
Occurs when the name of a zone object in one fabric is also used for a different type of zone object
in the other fabric. A zone object is any device in a zone
.
Symptom Fabric segmentation is caused by a “content mismatch”.
Probable cause and recommended action
Occurs when the definition in one fabric is different from the definition of a zone object with the
same name in the other fabric.
Zone conflicts
Zone conflicts can be resolved by saving a configuration file with the configUpload command,
examining the zoning information in the file, and performing a cut and paste operation so that the
configuration information matches in the fabrics being merged.
After examining the configuration file, you can choose to resolve zone conflicts by using the
cfgDisable command followed by the cfgClear command on the incorrectly configured segmented
fabric, then enter the cfgSave command followed by the portDisable and portEnable commands on
one of the ISL ports that connects the fabrics. This causes a merge, making the fabric consistent
with the correct configuration.
ATTENTION
Be careful using the cfgClear command because it deletes the defined configuration.
Table 14 summarizes commands that are useful for debugging zoning issues.
