EMC Fibre Channel and iSCSI with QLogic HBAs in the Windows Environment

Planning, Miscellaneous Procedures, and Troubleshooting

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.

Tape devices are treated the same as disk devices in Windows with respect to

persistent binding. Refer to your tape device documentation for more

information.
