Interop Mode; Configuring Switch Binding; Configuring Preferred Path - HP 316095-B21 Installation Manual

For example, in the audit log you may notice that the Principal setting maps to a number code of 1,
Default maps to a number code of 254, and Never Principal maps to a number code of 255. The
number codes of 2--253 are not currently in use.

Interop Mode

Select one of the following options:
• Homogenous Fabric—Select this mode if the fabric contains only HP Directors and Edge
Switches that are operating in Homogeneous Fabric mode.
• Open Fabric 1.0—Default. Select this mode if the fabric contains HP Directors and Edge
Switches, as well as other open-fabric compliant switches. Select this mode for managing
heterogeneous fabrics.

Configuring switch binding

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 Edge Switches that
can attach to Director and Edge Switch ports. This feature provides security in environments that
include a large number of devices by ensuring that only the intended set of devices attach to an
Edge Switch or Director. For complete procedures on configuring this optional feature, see the HP
StorageWorks Edge Switch Element Manager user guide.

Configuring preferred path

The preferred path feature lets you specify and configure one or more ISL data paths between
multiple Directors or Edge Switches in a fabric. Each participating Director or Edge Switch must be
configured as part of a desired path. The following rules apply when configuring a preferred path:
• The Edge Switch domain ID must be set to Insistent. For instructions, see
Switch operating
• Domain IDs range between 1 through 31.
• Source and exit port numbers are limited to the range of ports available on the Edge Switch (0
through 31).
• For each source port, only one path is defined to each destination domain ID.
NOTE:
preferred path differs from the current path, if input and output (I/O) is active from the source
port, and if congestion is present on the current path.
To configure one or more preferred paths for the Edge Switch:
1. At the Hardware view, select Configure > Preferred Path.
