Merging fabrics and zoning If you join two fabrics with an inter-switch link, the active zone sets from the two fabrics attempt to merge automatically. The fabrics may consist of a single switch or many switches already connected together. The switches in the two fabrics attempt to create a new active zone set containing the union of each fabric's active zone set. The propagation of zoning information affects only the active zone set, not the configured zone sets, unless Merge Auto Save is turned on. Zone merge failure If a zone merge is unsuccessful, the inter-switch links between the fabrics become isolated due to the zone merge failure, which generates an alarm. The reason for the E_Port isolation can also be determined by viewing the port information. See Table 17 for more information. A zone merge will fail if the two active zone sets have member zones with identical names, but differ in membership or type. For example, consider Fabric A and Fabric B each with a 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 would fail because the two zones have the same name, but different membership. A zone merge may also fail if the merged zones/members exceed the maximum zoning limits. See "Viewing zoning limits and properties" (page 37) for more information on zoning limits. 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 is 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. NOTE: If you deactivate the active zone set in one fabric and the Merge Auto Save parameter is enabled, the active zone set from the second fabric propagates to the first fabric and replaces all zones with matching names in the configured zone sets. For more information about adding and removing zone members, see "Managing zones" (page 43). For more information about resetting a port, see "Resetting a port" (page 98).

Merging fabrics and zoning

If you join two fabrics with an inter-switch link, the active zone sets from the two fabrics attempt to merge

automatically. The fabrics may consist of a single switch or many switches already connected together. The

switches in the two fabrics attempt to create a new active zone set containing the union of each fabric's

active zone set. The propagation of zoning information affects only the active zone set, not the configured

zone sets, unless Merge Auto Save is turned on.

Zone merge failure

If a zone merge is unsuccessful, the inter-switch links between the fabrics become isolated due to the zone

merge failure, which generates an alarm. The reason for the E_Port isolation can also be determined by

viewing the port information. See

Table 17

for more information.

A zone merge will fail if the two active zone sets have member zones with identical names, but differ in

membership or type. For example, consider Fabric A and Fabric B each with a 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 would fail because the

two zones have the same name, but different membership.

A zone merge may also fail if the merged zones/members exceed the maximum zoning limits. See

”

Viewing zoning limits and properties

” (page 37) for more information on zoning limits.

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 is 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.

NOTE:

If you deactivate the active zone set in one fabric and the Merge Auto Save parameter is enabled,

the active zone set from the second fabric propagates to the first fabric and replaces all zones with

matching names in the configured zone sets.

For more information about adding and removing zone members, see ”

Managing zones

” (page 43). For

more information about resetting a port, see ”

Resetting a port

” (page 98).
