HP Brocade 4Gb SAN Switch for HP BladeSystem p-Class - Manual (Page 187)

8. Issue the
configure
command to edit the fabric parameters for the segmented switch.
Refer to the HP StorageWorks Fabric OS 4.x command reference guide for more detailed
information.
9. Enable the switch by entering the
switchenable
command.
To download 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 75.
To reconcile a domain ID conflict:
If a domain ID conflict appears, the conflict is only reported at the point where the two fabrics are
physically connected. However, there might be several conflicting domain IDs, which appear as soon as
the initial conflict is resolved.
Repeat this procedures until all domain ID conflicts are resolved:
1. Issue the
switchshow
command on a switch from one of the fabrics.
2. Open a separate telnet window.
3. Issue the
switchshow
command on a switch from the second fabric.
4. Compare the
switchshow
output from the two fabrics. Note the number of domain ID conflicts; there
might be several duplicate domain IDs that need to be changed.
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 30 .
Table 30 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 of a in one fabric is different from the
definition of a zone object with the same name in the other fabric.
