HP StorageWorks Multi-protocol Router XPath OS 7.4.1e Release Notes (AV-RW5LN-TE, August 2007)
Issue
Description
• Existing versio
ns of Fabric Manager and other API-based applications that
manage zoning in edge fabrics ca n be used to configure LSAN zones that
create logical storage area networks by using the MP Router.
• API-based applications must be compiled with new API libraries to control
directly– supported MP Router functions. Those libraries will be available
at a later d ate.
• A FAL-based application connected to a Fabric OS v2.6 switch will not
properly interpret the presence of virtual switches and domains created
in routed fabrics.
Fibre Channel Class XPath OS supports only Fibre Channel Class 3. Testing has shown that Class 2
devices attached to and supported by Fabric OS-based pl atforms communicate
properly through FC-FC routing services on XPath OS 7.30b and are supp orted.
N[L]_Port devices that are connected directly to the MP Router and ca nnot
automatically or manually accept the F_Port’s request for Fibre Channel Class 3
are affected. The IBM AIX operating system configured with the IBM 6228 HBA
is known not to be able to accept Class 3 and therefore cannot register with the
XPath OS Fibre Channel Name Server.
Fibre Channel
Management Server
in-band support
XPath OS 7.4.0 does not support Management Server requests from hosts
connected to the switch. Login requests to the Management Server will be
rejected.
Name Ser
ver and
Zone Se
rver database
sizes
The Name Server and Zone Server databases support fabrics within (and
actually far larger than) the scalability guidelines. Fabric and zone merge
attemp
ts with fabrics beyond the sc alability limits presented in this document
will pr
event fabrics from merging.
Fibre C
hannel Routing Services does not participate directly with Name Server
and Zone Server databases on edge fabrics; rather, it consumes zones that
begin with the string LSAN_ only and creates Name Server entries in edge
fabri
cs for shared devices only.
Fibre Channel
Management Server
platform services
compatibility
XPath OS 7.4.0 is not compatible with the Fabric OS implementation of the
Fibre Channel Management Server platform services. If platform services are
enabled on a Fabric OS fabric and a merge is attempted with an XPath OS
7.4.0 fabric, the E_Port links between the fabrics will link and segment at
intervals; in effect, the fabrics will not merge.
The command msPlMgmtDeactivate should be executed on all Fabric OS
switches prior to any merge attempts with XPath OS.
Fabric OS open
E_Port is not
supported
Fabric OS open E_Port is not supported on XPath OS.
Tr
affic switching
In
asingleMPRouter,youcanconfigure a port to be FC, FCR, GbE iSCSI,
or GbE FCIP. Traffic switching is supported only between the following types
o
fports:
• F
C&FCR
• FC & GbE FCIP
• FC & GbE iSCSI
• FCR & FCIP
Traffic swi tching between other types of port combinations is not supported.
This applies to port combinations on the same p latform as well as across
independent platforms. For example, traffic from an i SCSI initiator connected to
a MP Router cannot be switched by an EX_Port on the same or independent
router .
