Iodset - HP StorageWorks 2/64 - Core Switch Command Reference Manual

iodSet

Enables the in-order delivery (IOD) option.
Synopsis
iodset
Availability
admin
Description
Use this command to enforce in-order delivery of frames during a fabric topology change.
In a stable fabric, frames are always delivered in order, even when the traffic between switches is shared
among multiple paths. However, when topology changes occur in the fabric (for instance, a link goes
down), traffic is rerouted around the failure and some frames might be delivered out of order. This
command ensures that frames are not delivered out-of-order, even during fabric topology changes.
The default behavior is for the IOD option to be off.
This command should be used with care, because it can cause a delay in the establishment of a new path
when a topology change occurs. Only if there are devices connected to the fabric that do not tolerate
occasional out-of-order delivery of frames, should this command be used.
