Installing and Configuring the Director

Configuring Preferred Path

The preferred path feature allows a user to specify and configure one or more ISL

data paths between multiple directors or switches in a fabric. Each participating

director or switch must be configured as part of a desired path. For complete

procedures on configuring this optional feature, refer to HP StorageWorks

Director Element Manager User Guide.

This feature is managed through the Switch Binding submenu options available

on the Element Manager Configure menu. Using Switch Binding, you can

specify devices and switches that can attach to director and switch ports. This

provides security in environments that include a large number of devices by

ensuring that only the intended set of devices attach to a switch or director. For

complete procedures on configuring this optional feature, refer to HP

StorageWorks Director Element Manager User Guide.

Perform this procedure to define Fibre Channel port names, configure ports as

blocked or unblocked, enable extended distance operation and Link Incident

(LIN) alerts, and define port types.

not change regardless of the device connected.

Figure
