Implementing SAN Internetworking Solutions 4 A No Zone Synchronization policy is typically not suitable for larger SAN routing environments where many devices must be visible to numerous fabrics. Append IPS Zones When the zone policy is set to Append IPS Zones, Internet protocol storage (IPS) zone set information from the router is appended to the active zone set for every router-attached fabric in the mSAN. In addition, all devices in the IPS zone set are added to the SNS of each fabric, even if the fabric does not have an active zone set. This policy is the default setting when an R_Port is configured. The Append IPS Zones policy is recommended and provides a balance between ease of use and retention of primary zoning control by Fibre Channel SAN management applications. Cross-fabric devices are zoned together (IPS zone set) through the SANvergence Manager application, and the zone is appended to the active zone set for each fabric (zoned through a SAN management application). Any subsequent changes made to the IPS zone set are propagated to the fabrics. NOTE: When using a SAN router with E/OSi Version 4.5 (or earlier), an active zone set must exist for each fabric prior to performing an Append IPS Zones operation. When using E/OSi Version 4.6 (or later), active zone sets are created automatically when the router zone is appended. The Append IPS Zones policy automatically creates common router zones in each attached fabric. In large environments where many devices must be visible to numerous fabrics, this policy is much easier than creating router zones manually (using the No Zone Synchronization policy). The IPS zone set appended to the active zone set of the fabric must not be modified using a Fibre Channel SAN management application. Changes made to the appended IPS zone set are immediately overwritten with the information previously configured at the SANvergence Manager application. Implementing SAN Internetworking Solutions 4-17
