McDATA 4Gb SAN Switch for HP p-Class BladeSystem release notes (AA-RW1ZH-TE, April 2008)

Important information
This section describes important information related to the McDATA 4Gb SAN Switch.
When running McDATA Web Server, Java plug-in c aching of temporary files
and
applets should be disabled
Java caching can cause the wrong version of McDATA Web Server to run. If caching is enabled and a
different version of McDATA Web Server is loaded from a switch, the version of McDATA Web Server
previously run will load from the cache instead. Also, if you have Java plug-in caching disabled, and you
upgrade your Java version, c aching may become enabled and will have to be disabled again.
Some feature management has been relocated
Secu rity functions are managed using the Element Manager or CLI, but not the McDATA Web Ser ver.
This is fully documented in the McDA T A 4Gb SAN Switch for HP p-Class BladeSystem user guide and
McDATA 4Gb SAN Switch for HP p-Class BladeSystem command line interface guide.
Differences between a McDATA 4Gb SAN Switch and HP StorageWorks
M-Series switches
This section lists the differences between a McDATA 4Gb SAN Switch and HP StorageWorks M-Series
Switches.
• The McDATA Web Server display s a McDATA Director or Edge S witch as McDATA EFCM
Manageable. EFCM and HAFM should be considered synonymous.
• In standard (open fabric) mode, which is the default mode, the default domain ID is 97; the
supported domain IDs are 97–127. HAFM displays this range as 1–31 (97–127) regardless of
the
mode.
• Note that the default interoperability mode is Standard or O pen Fabric, if the McDATA 4Gb SAN
Switch is being connected to an existing SAN operating in Homogeneous Fabric or McDATA
Fabric interop mode, the interop mode must be cha nge d in either the McDATA 4Gb SAN Switch
or the
other switches in the fabric.
• If the McDATA 4Gb SAN Switch is being attached to a fabric with other H P M-Series or McDATA
Switches, it is recommended to use HAF M/EFCM or Embedded Web Server/EFCM Basic to
manage
fabric-wide parameters, such as zoning and SANtegrity Fabric Binding.
• Use of hard zoning ACL is not recommended, as it is not compatible wi th other McDATA switches.
• The McDATA 4Gb SAN Switch supports por t/d omain zoning in Standard or Open Fabric interop
mode; other HP M-Series or McDATA switches do not. Therefore, only WWN zoning is supported
in Standard or Open Fabric interop mode when McDATA 4Gb SAN Switch is attached to other
HP M-Series or McDATA switches.
• FC address zoning is not supported by other HP M-Series or McDATA switches, so it is not
recommended for use in McDATA 4Gb SAN Switch.
• The McDATA 4Gb SAN Switch has the ability to acquire an IP add ress automatically using DHCP.
You can use D HCP to initially access the switch and assign it a fixed address. This assumes that
you can determine the assigned IP address. If you cannot determine the assigned address,
you will be unable to access and manage the switch. To definitively access all switches in the
environment with known IP addresses, static I P assignment is the recommended method to use.
• The McDATA 4Gb SAN Switch does not have a configurable Reroute Delay feature as with the
other
HP M-Series Directors and Edge Switches. The McDATA 4Gb SAN Switch will opera te
properly whether other HP M-Series Directors and Edge Switches in the fabric have this feature
enabled or d isabled.
• The Default Zone parameter enables (True) or disables (False) communication amon g ports or
devices that are not defined in the active zone set or when there is no active zo ne set. This
parameter must have the same value throughout the fabric. If interop mode is M c DATA Fabric
Mode, the Default Zone parameter is automatically distributed throu ghout the fabric.
