Set up Persistent Binding - Introduction

The persistent binding feature allows you to control the devices that are to be presented to the system. You can set up persistent binding using either lputilnt or HBAnyware.

• lputilnt allows you to set up persistent binding on local adapters only.

• HBAnyware allows you to set up persistent binding on remote and local adapters.

The Emulex SCSIport Miniport driver detects all devices attached to the Emulex host bus adapters (HBAs). Global automapping assigns a binding type, target ID, SCSI bus and SCSI ID to the device. The binding type, SCSI bus and SCSI ID may change when the system is rebooted. When persistent binding is applied to one of these targets, the binding type, SCSI bus and SCSI ID remain the same, whether the system is rebooted or whether Global Automap All Targets is subsequently enabled (disabled by default in lputilnt).

The binding information is permanent because it is stored in the Windows registry. The driver refers to the binding information at bootup.

Persistent binding permanently maps a device to the following:

• Binding type (world wide port name (WWPN), world wide node name (WWNN), or a destination identifier (D_ID)

• SCSI bus

• SCSI ID
