2006 Model L10 Storage Switch

LIP on Insert Policy 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.
LIP on Removal Policy 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.
Port Test Before Insert Policy This policy ensures a device on a port is a valid,
standards-compliant participant before allowing the
device to be inserted into a zone. The device must meet
all of the FC-AL requirements along with going through
a complete change notification cycle. During the change
notification cycle, the device becomes the Initialization
Master (IM) and goes through the change notification
phases. Once the change notification cycle is complete,
the device can be inserted. This process ensures a bad
device is not allowed into the zone.
