Enable/Disable
and online state
functions
In order for Fabric Binding to function, specific operating parameters
and optional features must be enabled. Also, there are specific
requirements for disabling these parameters and features when the
switch is offline or online. Be aware of the following:
• Because switches are bound to a fabric by world wide name
(WWN) and domain ID, the Insistent Domain ID option in the
Configure Switch Parameters dialog box is automatically enabled if
Fabric Binding is enabled. You cannot disable Insistent Domain
ID while Fabric Binding is active and the switch is online.
• If Fabric Binding is enabled and the switch is online, you cannot
disable Insistent Domain ID.
• If Fabric Binding is enabled and the switch is offline, you can
disable Insistent Domain ID, but this will disable Fabric Binding.
• You cannot disable Fabric Binding or Switch Binding if Enterprise
Fabric Mode is enabled. However, if Enterprise Fabric Mode is
disabled, you can disable Fabric Binding, Switch Binding, or both.
For more
information
To enable, disable, and configure this option, refer to the Fabric
Binding section of Chapter 8, “Optional Features,” in the EFC
Manager Software Release 8.3 User Manual for IBM TotalStorage Products.
Switch binding
This feature is managed through the Switch Binding submenu options
available on the element manager Configure menu. Using Switch
Binding, you can specify devices and switches that can attach to
switch ports. This provides security in environments that include a
large number of devices by ensuring that only the intended set of
devices attach to a switch or director.

Membership List in the Switch Binding - Membership List dialog box
(element manager) with the following WWNs currently connected to
the switch, depending on the connection policy set in the State Change
dialog box:
