Planning Considerations for Fibre Channel Topologies 3 However, the firmware and SAN management applications do not prevent FCP and FICON device configurations that may interfere with each other. A successful intermix environment requires a set of best practice conventions as follows: 1. Upgrade fabric element firmware to a common version - Ensure fabric elements are operating at a common firmware level. This reduces errors due to director or switch incompatibility. E/OS Version 4.0 or higher is required to support FICON cascading. E/OS Version 6.0 or higher is recommended. 2. Upgrade fabric element software to a common version - Ensure fabric elements are operating at a common software level. This simplifies fabric fault isolation and reduces errors due to director or switch incompatibility. SANavigator 4.0 or EFCM 8.0 (or higher) is required to support a unified management style and is recommended. - When a director or switch is set to open systems management style, a traditional Fibre Channel fabric is supported. Inband management through the FMS or OSMS is also supported. The key concern is to avoid disrupting installed FCP devices when connecting FICON devices to a fabric element and modifying configurations to facilitate FICON communication. The Element Manager application does not use logical port addressing or display the Configure Allow/Prohibit Matrix Active dialog box. A PDCM array is not supported, and the HCD defined by an attached host describes FICON connectivity requirements. - When a director or switch is set to FICON management style, either multiple domains (fabric elements) are supported, or only a single domain (fabric element) is supported, depending on the firmware release level. Inband management through the FMS or OSMS is also supported. The Element Manager application provides a PDCM array configured at the Configure Allow/ Prohibit Matrix - Active dialog box. The array activates all or a subset of the connectivity paths established by a host-based HCD. When using firmware prior to E/OS Version 4.0 and the FICON management style, ports are set to F_Port operation, thus eliminating E_Port capability (ISL and fabric capability). 3-48 McDATA Products in a SAN Environment - Planning Manual
