EMC Fibre Channel with QLogic HBAs in Windows Hosts

Introduction

The next figure shows the same host after the cable attached to HBA0

has been removed and the host rebooted. Since Windows was not

able to do a discovery on HBA0, it assigned \\PHYSICALDRIVE0

to the first device it discovered. In this case, that first device is

connected to HBA1. Due to the shift, any software application

accessing \\PHYSICALDRIVE0 will not find data previously

written on the original \\PHYSICALDRIVE0.

The default driver behavior does not store target bindings between

host reboots. The bindings are dynamically generated by the HBA

when new target devices are detected.
