Abstract: So you think you know all about the OSA-E3 or OSA-E4S multi-port design? Did you know that you may not be able to seamlessly transfer a network design of a pair of two-port adapter cards to the four ports of a single OSA-E3 adapter or even the two ports of an OSA-E4S?
Did you know that the IOCDS or HCD definitions must correlate with the OSA firmware table known as the “OAT” in order for the channel path to come online during a migration?
This document is a brief introduction to problems you want to avoid when ordering and planning for new OSA configurations. An appendix contains a list of valuable reference documents and presentations that you may use when working on a new OSA order or implementation.
