This information displays in the identification table at the top of the Hardware view and in
the HAFM Physical/Topology Map, if the Physical/Topology Map is configured to display names.
Operating Parameters
This option offers the ability to configure switch and fabric parameters.
•
Click Switch Parameters to display the Configure Switch Parameters dialog box for setting Fibre
Channel operating parameters. In this dialog box, you can set the preferred domain
identification (1 to 31) and make it insistent. You can also enable rerouting delay, domain
register for state change notifications (RSCNs), and Suppress RSCNs on zone set activation. In
addition, you can also set the director data speed (Director 2/64 only). The director must be
offline to configure switch speed, preferred domain ID.
•
Click Fabric Parameters 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. See ”
” on page 95 for more information on configuring these parameters for the director.
The director must be offline to configure any fabric operating parameter.
Preferred Path
Select this option to configure an ISL between switches and directors. The ISL will consist of the
source port of the switch being configured, the exit port of the same switch, and the domain ID of
the destination switch. Each switch must be configured for its part of the desired path for optimal
performance. You may need to configure preferred paths for all switches along the desired path for
proper multi-hop preferred path operation. For more details about this feature, see ”
Switch Binding
This option has two suboptions: Change State and Edit Membership List.
•
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
Restrict 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 Binding feature key. The feature can be installed through the Configure Feature Key
dialog box. For more information, see ”
