192.168.0.0 through 192.168.0.255—This subnet is used internally to the HAFM
appliance. Using an IP ad dress in this range causes the call-home feature to function
incorrectly.
Hard zoning
Hard zoning is a security enhancement introduced in firmware 05.01.00-24 that
prevents ports from accessing devices outside their zones. Hard zoning is enabled
by default when using firmware 05.01.00-24 or greater and cannot be disabled. All
HP-approved host bus adapters (HBAs) limit access to devices within their zones, so you
will not see a c
hange in fabric behavior unless you are using nonstandard HBAs. Ha rd
zoning improves security against intruders that load nonstandard HBA drivers.
Hard zoning is compatible with legacy zone definitions, including World Wide Name
(WWN) and port zoning. You can use your existing zones and zone sets without any
changes. There are no changes to the zoning interfaces, so you do not need to modify
your zone management practice, modify your documentation, or retrain Storage Area
Network (SA
N) administrators.
Hard zoning controls access at the ingress port. When a por t attempts to send a frame
to a destination outside its zones, the frame is blocked. A Class 2 frame is fabric
rejected, and a Class 3 frame is dropped.
Zoning change RSCN control
Normally, when a zone set is activated, a fabric format domain Register State Change
Notification (RSCN) is sent to all devices in the fabric. With firmware 05.00.00 or later,
you c an disable these RSCNs from being sent. This is done using the Suppress RSCNs
on zone set activations check box on the Config ure Switch Parameters dialog b ox.
This feature significantly changes the normal behavior of the fabric. Devices will have no
warning when zones change a nd will not automatically update their zoning information.
The ability to suppress RSCNs is disabled (check box is not selected) by default. This
feature can be configuredthroughHAFM,EWS,andCLI.
