Description

 

 

Stealth Intelligent Change

Stealth Intelligent Change Manager provides stability and control

Manager

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-1Note: This setting should not be used unless

 

directed to do so by a customer service representative.

 

 

Change Notification on

The switch normally operates under the condition that when a

Insertion

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

This policy is similar to the Change Notification on Insertion policy,

Removal

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.
