3. Compare the fabricShow output from the two fabrics. Note the number of Domain ID conflicts; there
may be several duplicate Domain IDs that must be changed. Determine which switches have domain
overlap and change the Domain IDs for each of those switches.
4. Choose the fabric on which to change the duplicate Domain ID; connect to the conflicting switch in that
fabric.
5. Enter the switchDisable command.
6. Enter the switchEnable command.
This will enable the joining switch to obtain a new Domain ID as part of the process of coming online.
The fabric principal switch will allocate the next available Domain ID to the new switch during this
process.
7. Repeat step 4 through step 6 if additional switches have conflicting Domain IDs.
Correcting zoning setup issues
Table 68 lists the types of zone configuration discrepancies that can cause segmentation.
Table 69 summarizes commands that are useful for debugging zoning issues.
Table 68 Types of zone discrepancies
Conflict cause Description
Configuration
mismatch
Occurs when zoning is enabled in both fabrics and the zone
configurations that are enabled are different in each fabric.
Type mismatch 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.
Content mismatch Occurs when the definition in one fabric is different from the definition of a
zone object with the same name in the other fabric.
