Insistent; Rerouting Delay - HP Surestore 64 - Director Switch User Manual

For more information on domain ID, refer to the section on domain ID assignment
for multiswitch fabrics in the HP StorageWorks SAN High Availability Planning
Guide for details.

Insistent

This option is not supported unless the SANtegrity Binding feature is installed.
Click the check box to remove or add a check mark. The default state is disabled
(no check mark).
When a check mark displays, the domain ID configured in the Preferred Domain
ID field will become the active domain identification when the fabric initializes.
See the following notes:

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 director is
in a multiswitch fabric. The default state is enabled.
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 director 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 Configure Fabric Parameters dialog box. This delay
allows frames sent on the old path to exit to their destination before new frames
begin traversing the new path.
Director Product Manager User Guide
This option is required if Enterprise Fabric Mode (optional SANtegrity
Binding feature) is enabled.
If you enable Insistent Domain while the switch or director is online, the
Preferred Domain ID will change to the current active domain ID if the IDs
are different.
Caution: If a director with a duplicate domain ID exists in the fabric, both
directors' E_Ports will segment when they try to join.
