in order delivery - IOD feature

Hi,

i have not clear when IOD should be enabled:

- is it true that IOD is in effect only when port based routing is enabled?

- how can i establish if my storage devices are supporting out-of order-delivery of frames?

thanks

Re: in order delivery - IOD feature

AFAIK:  IOD is  mandatory for FICON. On IBM switches IOD was enabled as default in the past.

Ask your storage vendor if they recommend to enable IOD or not.

IDO works on port and exchanged based routing policy.

I hope this helps,

Andreas

IOD is mandatory for FICON environments.

Some hardware-based replication solutions such as HP's Continuous Access EVA (classic mode) also require IOD.

IOD frequently works together with Port-Based Routing (aptpolicy) and Sticky Routes (dlsreset) but these can be configured independently.

Most likely not.

But technically these are different settings.
