Change Notifications
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
generated 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
notifications 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 that 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 that the proper system updates are performed.
