Duplicate WWN detection and resolution Fabric OS 7.0.0a implements a feature to detect duplicate device WWNs in a fabric. It also enables users to configure a policy to take action once duplicate WWNs are detected. RASlog upon detecting Invalid TI zones In a failover disabled configuration of a TI zone, if the switch (domain) becomes unreachable, users are informed about this domain unreachable condition via a RASlog message, which helps users to diagnose and resolve this problem quickly. Ability to assign names to logical fabrics The fabric naming feature allows users to assign a user friendly name to identify and manage a logical fabric. No direct E_Port support with legacy M-series (McDATA) switch Fabric OS 7.0.0a supports only interopmode 0 and does not support interoperability with an M-series (McDATA) switch via direct E_Port connectivity. FCR can be used to establish connectivity between a fabric with an M-series switch and a fabric with a switch running Fabric OS 7.0.0a. Additional RAS and Diagnostics Enhancements Spinfab enhancements The spinfab diagnostics utility has been enhanced to test ISLs at higher link utilization by using all buffers available at a port. This feature is supported on both 8 Gbps and 16 Gbps FC platforms. Frame Viewer The Frame Viewer feature introduced in Fabric OS 7.0.0a provides more visibility to SAN administrators regarding discarded frames due to timeout. This feature is supported both on 8 Gbps and 16 Gbps platforms. Port Decommission The Port Decommission feature provides users with the ability to non-disruptively remove an ISL from service. When an ISL is selected for decommissioning, the switches communicate with each other to coordinate the movement of flows off of the ISL to alternative paths. Once the flows are moved to alternative paths, the switches block the E_Ports associated with the ISL being decommissioned to complete the decommission process.

Duplicate WWN detection and resolution
Fabric OS 7.0.0a implements a feature to detect duplicate device WWNs in a fabric. It also enables
users to configure a policy to take action once duplicate WWNs are detected.
RASlog upon detecting Invalid TI zones
In a failover disabled configuration of a TI zone, if the switch (domain) becomes unreachable, users
are informed about this domain unreachable condition via a RASlog message, which helps users to
diagnose and resolve this problem quickly.
Ability to assign names to logical fabrics
The fabric naming feature allows users to assign a user friendly name to identify and manage a logical
fabric.
No direct E_Port support with legacy M-series (McDATA) switch
Fabric OS 7.0.0a supports only interopmode 0 and does not support interoperability with an M-series
(McDATA) switch via direct E_Port connectivity. FCR can be used to establish connectivity between a
fabric with an M-series switch and a fabric with a switch running Fabric OS 7.0.0a.
Additional RAS and Diagnostics Enhancements
Spinfab enhancements
The spinfab diagnostics utility has been enhanced to test ISLs at higher link utilization by using all
buffers available at a port. This feature is supported on both 8 Gbps and 16 Gbps FC platforms.
Frame Viewer
The Frame Viewer feature introduced in Fabric OS 7.0.0a provides more visibility to SAN administrators
regarding discarded frames due to timeout. This feature is supported both on 8 Gbps and 16 Gbps
platforms.
