Zone Merge Failure
If a zone merge is unsuccessful, the inter-switch links between the fabrics will
isolate due to a zone merge failure, which will generate an alarm. The reason for
the E_Port isolation can also be determined by viewing the port information. Refer
to ”Port Information Data Window” on page 6-7 and the ”Show Command” on
page A-50 (Port keyword).
A zone merge will fail if the two active zone sets have member zones with
identical names that differ in membership or type. For example, consider Fabric A
and Fabric B each with a soft zone named “ZN1” in its active zone set. Fabric A
"ZN1" contains a member specified by Domain ID 1 and Port 1; Fabric B “ZN1”
contains a member specified by Domain ID 1 and Port 2. In this case, the merge
will fail because the two zones have the same name, but different membership.
The zone merge will also fail if Fabric A “ZN1” is a soft zone and the Fabric B
“ZN1” is an ACL zone.
3.4.4.2
Zone Merge Failure Recovery
When a zone merge failure occurs, the conflict that caused the failure must be
resolved. You can correct a failure due to a zone conflict by deactivating one of
the active zone sets or by editing the conflicting zones so that their membership
and zone type (soft, ACL, VPF) are the same. You can deactivate the active zone
set on one fabric if the active zone set on the other fabric accurately defines your
zoning needs. If not, you must edit the zone memberships, and reactivate the
zone sets. After correcting the zone membership, reset the isolated ports to allow
the fabrics to join.
Refer to ”Managing Zones” on page 3-25 for information about adding and
removing zone members. Refer to ”Resetting a Port” on page 6-14 for information
about resetting a port.
Note: If you deactivate the active zone set in one fabric and the Auto Save
parameter is enabled, the active zone set from the second fabric will
propagate to the first fabric and replace all zones with matching names
in the configured zone sets.
