8. Issue the configure command to edit the fabric parameters for the segmented switch. See the HP StorageWorks Fabric OS 5.x command reference guide for detailed information. 9. Enable the switch by issuing the switchEnable command. You can also reconcile fabric parameters by issuing the configUpload command for each switch. Downloading a correct configuration You can restore a segmented fabric by downloading a previously saved correct backup configuration to the switch. Downloading in this manner reconciles any discrepancy in the fabric parameters and allows the segmented switch to rejoin the main fabric. For details on uploading and downloading configurations, see "Maintaining configurations" on page 73. Reconciling a domain ID conflict If a domain ID conflict appears, the conflict is reported only at the point where the two fabrics are physically connected. However, there might be several conflicting domain IDs, which appears as soon as the initial conflict is resolved. Typically, the fabric resolves domain conflicts during fabric merges or builds unless IDID is configured. If IDID is enabled, switches that cannot be programmed with a unique domain ID are segmented out. Check each switch that has IDID enabled and make sure their domain IDs are unique within the configuration. Repeat this procedure until all domain ID conflicts are resolved: 1. Issue the fabricShow command on a switch from one of the fabrics. 2. In a separate telnet window, issue the fabricShow command on a switch from the second fabric. 3. Compare the fabricShow output from the two fabrics. Note the number of domain ID conflicts; there might be several duplicate domain IDs that need to be changed. 4. Determine which switches have domain overlap and change the domain IDs for each of those switches. 5. Chose the fabric on which to change the duplicate domain ID; connect to the conflicting switch in that fabric. 6. Issue the switchDisable command. 7. Issue the switchEnable command. This enables the joining switch to obtain a new domain ID as part of the process of coming online. The fabric principal switch allocates the next available domain ID to the new switch during this process. 8. Repeat step 5 through step 7 if additional switches have conflicting domain IDs. Correcting zoning setup issues The types of zone configuration discrepancies that can cause segmentation are listed in Table 24. Table 24 Types of zone discrepancies Conflict Description Configuration mismatch Type mismatch Content mismatch Occurs when zoning is enabled in both fabrics and the zone configurations that are enabled are different in each fabric. 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. Occurs when the definition in one fabric is different from the definition of a zone object with the same name in the other fabric. Table 25 summarizes commands that are useful for debugging zoning issues. Fabric OS 5.x administrator guide 149
