HP StorageWorks 16-EL HP StorageWorks SAN Switch 2/16 Fabric OS V3.1.2 Release - Page 7

Important Notes Important Notes This section provides information you should be aware of when running Fabric OS v3.1.2. OS Requirements HP recommends using the latest software release versions to get the greatest benefit from the SAN. Mixed Fabric Environment with Different Switch Platforms Fabric OS v2.6.2, v3.1.2, and v4.2.x introduced a new switch PID format: Extended Edge PID (Format 2). Extended Edge PID is useful if you introduce a Fabric OS v4.2.x switch into a fabric consisting solely of Fabric OS v2.x/v3.x switches. Before adding a Fabric OS v4.2.x switch to such a fabric, refer to the HP StorageWorks Fabric OS 4.2.x Procedures User Guide for information on the Extended Edge PID format. Note: Switches must operate with Fabric OS v2.6.2, v3.1.2, or v4.2.x to use the Extended Edge PID format. If Extended Edge PID is set (before a downgrade from the current Fabric OS release to an earlier Fabric OS release that does not support the Extended PID format), PID needs to be set back to a supported format, such as Core PID (format 1) or native PID (format 0). Advanced Web Tool Updates The following is a list of Advanced Web Tools updates for this release: ■ Advanced Web Tools integrated management Graphical User Interface (GUI) recognizes HP StorageWorks switches released after Fabric OS v3.1.2 as generic 16-port switches. ■ When using a mixed fabric-that is, a fabric that contains v4.x, v3.x, and v2.x switches-HP recommends that you use the most advanced switches to control the fabric. For example, use the v4.x switches as the primary Fibre SAN Switch 2/16 Fabric OS 3.1.2 Release Notes 7
