Offline BER test on FICON channels

On IBM DS8K products we are able to perform an offline Bit ERror (BER) test to check a FICON link's quality while the path is offline but the cables are connected. My understanding is that this is accomplished by using idle characters being sent o...

NPIV support in HCD and IOCP

The NPIV setting of an FCP channel would be better driven from IOCP. In this way, a customer would eliminate a step in configuring FCP channels if NPIV were desired. Hard to imagine that a customer would have two different settings for an FCP chan...

Greater than 256 LCUs per channel

We are currently using exactly 256 LCUs on some of our channels, which is the limit according to HCD when building IODFs and also according to those at IBM we've spoken to on the subject. Our ongoing adoption of MzGMM with a Flashcopy has added mo...
