The following settings are available.
Setting Description
Stealth Intelligent Change
Manager
Stealth Intelligent Change Manager provides stability and control over
change notification disruptions on a port basis. Options include:
• Off: No Change Protection – no Stealth Intelligent Change Manager
control.
• Initiator: Only Receive Changes – devices attached to the port can
receive change notifications but will not propagate change notifications
generated by that port to other ports.
• Target: Only Send Changes – propagates change notifications gener-
ated by the port to other ports but will not allow devices attached to the
port to receive change notifications from other ports.
• Switch-Switch: Send and Receive Changes – allows change notifica-
tions to propagate between switches.
• Custom-1 – Note: This setting should not be used unless directed to do
so by a customer service representative.
Change Notification on
Insertion
The switch normally operates under the condition that when a device is
inserted onto the network, a change notification is generated. However,
this condition is not always true when connecting hubs or switches
together. In some instances, it is possible to connect two zones together
without the zones realizing that multiple AL_PAs exist with the same
values.
When this policy is enabled, the switch always generates a change
notification to ensure the proper system updates are performed. However,
when a device is removed (for example, an initiator or target), the removal
does not generate a change notification and there are no system updates
performed.
Change Notification on
Remova
l
This policy is similar to the Change Notification on Insertion policy, except
for the change notification being sent when a device is removed rather
than inserted.
When this policy is enabled, the switch always generates a change
notification to ensure the proper system updates are performed.
