Hi Sasha, [This is a repost w/ updates and updated patches from my posts Dec 09, I assume the patches fell off your list :-)]
I've added two new functions into libibnetdisc, ibnd_cache_fabric() and ibnd_load_fabric(). As the names suggest, these functions allow the user to store the ibnd_fabric_t fabric to disk and read it back later on. The patches add the functions and the base functionality to ibnetdiscover, iblinkinfo, and ibqueryerrors. Some of the current and future benefits of this are: - Give users the option to have IB diag tools load the cached version of the fabric instead of scanning the IB fabric. Not only does this make the tools faster, it allows users to debug, analyze, play, etc. with a fabric state that existed in the past. Or a fabric that they don't even have access to (e.g. send the current fabric to support staff). - Support new debug/analysis features into IB diag tools. One example is a "diff" type of debug/analysis feature that allows users to compare how the current fabric state is different than a previous time. Another idea is a "filter" type of option. Some users who have a number of unpopulated switch ports have said they'd like to limit the output of the diag tools.
