HP StorageWorks 2/140 director product manager user guide - Page 36

Product Manager Overview you can also set the director data speed (Director 2/64 only) and set the director operating mode to S/390 or Open Systems modes. The director must be offline to configure director speed, preferred domain ID, and operating mode. • Fabric Operating Parameters-Choose this option to display the Configure Fabric Parameters dialog box for setting fabric operating parameters. In this dialog box, you can set buffer-to-buffer credit (BB_Credit) from 1 to 60 (default is 16) and the resource allocation time-out value (R_A_TOV) and error detect time-out value (E_D_TOV) in tenth-of-a-second increments. In addition, you can set the switch priority level (Principal, Default, or Never Principal) and the interoperability modes between Homogeneous, and Open Fabric 1.0. Refer to "Configuring Fabric Operating Parameters" on page 3-6 for more information on configuring these parameters for the director. The director must be offline to configure any fabric operating parameter. • Switch Binding-This submenu provides two options: Change State and Edit Membership List. Choosing Change State displays the Switch Binding State Change dialog box where you can activate Switch Binding according to a specific connection policy (Restrict E_Ports, Restrict F_Ports, or All Ports). Edit Membership List allows you to create a list of switches and devices that you want to allow exclusively to attach to director ports. Switch Binding is an optional feature that requires the SANtegrity Feature key. The feature can be installed through the Configure Feature Key dialog box. For details, refer to "SANtegrity Features" on page 6-6. • Ports-Choose this option to display the Configure Ports dialog box. This dialog has different functions in S/390 versus open systems mode. In S/390 mode, use the dialog box to enable extended distance buffering for 10 to 100km, link incident (LIN) alerts, and port binding for each port. In open systems mode, for each port you can provide a name, block or unblock operation, configure extended distance buffering for 10 to 100km, enable LIN alerts for each port, define a type (G, F, and E), and enable port binding. NOTE: Ports are automatically configured as G_Ports if no device is connected, F_Ports if a device is connected, and E_Ports if a director is connected. In both modes, you can enable the rerouting delay feature and for the Director 2/64, you can set the director data speed. NOTE: Your director model and firmware may not allow variable data speeds. • Addresses-S/390 mode only. Choose from two suboptions for active and stored addresses. 1-18 director product manager user guide
