3.4.3

Restoring Default Zoning

Restoring the default zoning clears the switch of all zoning definitions.

CAUTION! This command will deactivate the active zone set.

To restore the default zoning for a switch:

1.In the faceplate display, open the Zoning menu and select Restore Default Zoning.

2.Choose the OK button to confirm that you want to restore default zoning and save changes to the zoning database.

3.4.4

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. 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 only affects the active zone set, not the configured zone sets.

3.4.4.1

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 5-7and the ”Show Command” on page A-47(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.
