About this document
OSMS change
Open Systems Management Server (OSMS) is now available as a standard
feature. OSMS can be enabled/disabled via EWS, Command Line Interface (CLI),
and HAFM.
Default zone is disabled by default
The default zone on the Edge Switch 2/12, Edge Switch 2/24, and Edge
Switch 2/32 is disabled by default. Zoning must be configured in order for any
devices connected to the edge switches to communicate.
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
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
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 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 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, modify your 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 is
fabric rejected, and a Class 3 frame is dropped.
