Important Information Some IP Addresses must be Avoided If you use HAFM to manage other M-Series Fabric directors and edge switches, when you select IP addresses for edge switches, directors, and for the HAFM server/appliance, do not use IP addresses in the following range: ■ 192.168.0.0 through 192.168.0.255-This subnet is used internally to the HAFM server/appliance. Using an IP address in this range causes the call-home feature to function incorrectly. Hard Zoning Hard Zoning is a security enhancement introduced in firmware Version 05.01.00-24 that prevents ports from accessing devices outside their zones. Hard Zoning is enabled by default when using firmware Version 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 change in fabric behavior unless you are using nonstandard HBAs. Hard 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, documentation, or retrain Storage Area Network (SAN) administrators. Hard Zoning controls access at the ingress port. When a port attempts to send a frame to a destination outside its zones, the frame is blocked. A Class 2 frame will be fabric rejected, and a Class 3 frame will be 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 Version 05.01.00-24 or later, you can disable these RSCNs from being sent. This is done using the Suppress RSCNs on zone set activations check box on the Configure Switch Parameters dialog box. This feature significantly changes the normal behavior of the fabric. Devices will have no warning when zones change and 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 configured through HA-Fabric Manager (HAFM), Embedded Web Server (EWS), and the Command Line Interface (CLI). Director Release Notes 15

Director Release Notes
Some IP Addresses must be Avoided
If you use HAFM to manage other M-Series Fabric directors and edge switches,
when you select IP addresses for edge switches, directors, and for the HAFM
server/appliance, do not use IP addresses in the following range:
■
192.168.0.0 through 192.168.0.255—This subnet is used internally to the
HAFM server/appliance. Using an IP address in this range causes the
call-home feature to function incorrectly.
Hard Zoning
Hard Zoning is a security enhancement introduced in firmware Version
05.01.00-24 that prevents ports from accessing devices outside their zones. Hard
Zoning is enabled by default when using firmware Version 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 change in fabric behavior unless
you are using nonstandard HBAs. Hard 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, documentation, or retrain Storage
Area Network (SAN) administrators.
Hard Zoning controls access at the ingress port. When a port attempts to send a
frame to a destination outside its zones, the frame is blocked. A Class 2 frame will
be fabric rejected, and a Class 3 frame will be 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
Version 05.01.00-24 or later, you can disable these RSCNs from being sent. This
is done using the
Suppress RSCNs on zone set activations
check box on the
Configure Switch Parameters dialog box.
This feature significantly changes the normal behavior of the fabric. Devices will
have no warning when zones change and 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 configured through HA-Fabric Manager
(HAFM), Embedded Web Server (EWS), and the Command Line Interface (CLI).
