Configuring the Switch

NOTE: We recommend configuring switch priority as Default. If you are considering changing

this value to something other than the default, refer to sections on principal switch selection for

multiswitch fabrics in the hp StorageWorks product in a SAN environment: planning guide for

director 2/64, edge switch 2/16, and edge switch 2/32 (A6534-96025/AA-RS2DA-TE) for details.

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 2-253 are no longer in use.

•Rerouting Delay

Placing a check mark in the check box to the left of the Rerouting Delay option

enables rerouting delay. This option is only applicable if the configured switch is

in a multiswitch fabric.

Enabling the rerouting delay ensures that frames are delivered in order through the

fabric to their destination. If there is a change to the fabric topology that creates a

new path (for example, a new switch is added to the fabric), frames may be routed

over this new path if its hop count is less than a previous path with a minimum

hop count. This may result in frames being delivered to a destination out of order

since frames sent over the new, shorter path may arrive ahead of older frames still

in route over the older path.

If rerouting delay is enabled, traffic ceases in the fabric for the time specified in

the E_D_TOV field of the dialog box. This delay allows frames sent on the old

path to exit to their destination before new frames begin traversing the new path.

The operating parameters are stored in NV-RAM on the switch.

Procedure

To configure Fibre Channel operating parameters for the switch, use the following

steps:

1. Configure the switch offline.

NOTE: Setting the switch offline terminates all Fibre Channel connections.

a. Select Set Online State from the Maintenance menu on the menu bar.

The Set Online State dialog box displays as shown in Figure 3–4.
