I assume the binding in question is the physical address binding for loop communications. The LIP (loop initialization process) for FC loops is defined to make several passes based on a number of criteria for establishing addresses on the loop. As far as I know there are no ways to guarantee a persistent address can be kept as the algorithms used in LIPs are designed to resolve conflicts that could occur.
From a practical perspective, if you connect the loop to a switch and the loop devices all the public loop spec, the switch will maintain the address mapping for all loop devices. Still, this cannot guarantee persistent address binding for all cases.

So what is SAN School? If this is the first time you are asking yourself, "What's a SAN?" -- SAN School is for you. If you are implementing your first SAN and need implementation and migration help -- SAN School is for you. If you are far along in the SAN process and need to extend your SANs or connect SAN islands -- SAN School is for you.
The authors of "Storage Area Networks for dummies", Christopher Poelker and Alex Nikitin, are your SAN School professors. Through 15-minute Webcast lessons, they covered SANs from A to Z, from what a SAN is, to connecting those last nodes for optimal performance.SearchStorage.com readers sent Chris and Alex received a lot of questions during each SAN School Webcast lesson. Since each lesson only lasted 15 minutes, they weren't able to answer all of your questions. Thanksfully, though, Chris Poelker was kind enough to answer them after each lesson.
The editors of SearchStorage.com have taken each of your questions and Chris's answers and posted all of them for you here. Also, if you missed any of teh SAN School Webcasts, click here
