HP StorageWorks Multi-protocol Router XPath OS 7.4.1d Release Notes (AV-RW5LM-TE, March 2007)

NOTE:
If an E_Port connection i s inadvertently created to the router from a n edge fabric, disconnect
the cable, stop the port on the router (as described above), and remove all configuration
and zoning from the ro uter (if necessary). If the connection was meant to be an EX_Port,
then create it on the router, reconnect the cable, and restart the port.
Important information
This section describes important information and important notes for the XPath OS 7.4.1c release.
Important notes
Table 6 through Table 11 list issues you should be aware of when using XPath OS 7.4.1c and the
HP StorageWorks MP Router.

Issue
Description
Unexpected LSAN Zone Update
messages or unexpected physical
device offline messages
These messages can occur during normal operation. However, if the MP Router
reports numerous occurrences that cannot be correlated to actual initiated events,
such as planned device reconfigurations or reboots, examine low-level port error
counts using the portstatsshow command.
Faulty cables and SFPs that cause interruptions in EX_Port connectivity might also
cause unexpected fabric reconfigurations. In the event of unexpected fabric
reconfigurations, ensure that there are no low-level errors occurring on ports and
focus diagnostic efforts on cables and SFPs.
Zoning restrictions for LSA N zones
and local fabric zones
Remote WWNs cannot be in both a Logical Storage Area Network (LSAN) zone
and a local fabric zone of fabrics that they do not physically reside in. Putting them
in both locations, may result in excessive boot times for host or servers in fabrics
connected to the MP Router.
IfaremotenodeWWNisinanLSANzone,thenitcannotalsobeinalocal
non-LSAN zone in a fabric that it does not physically reside in. For example, if
youhaveahostorstoragedevicedefinedinaremotefabriczoneandyouwish
to add either of these devices to a n LSAN zone, you need to ensure that these
devices are not listed in any local zones other than the physical fabric they reside
in. LocalWWNsareallowedinbothanLSANzoneandthelocalzonesofthe
fabric where they are physically located.
Fabric ID oversubscribed message
The port error Fabric ID oversubscribed displays if you configure multiple
EX-port connections to the same fabric using different Fabric IDs. While the Fabric
ID used for each fabric connected to the MP Router is unique, all EX-ports connected
tothesamefabricfromtheMPRoutermustusethesameFabricID.
HBA configuration In certain large routed fabrics with large numbers of EX_Ports (for example, ≥8)
connected to each fabric (usually done for bandwidth for large numbers of s hared
initiators and targets across fabrics) and a large number of shared devices (for
example, ≥800), set the PLOGI timeout value for 1 Gbps JNI FC HBAs to 3000
ms. This will allow time for the routed fabric to answer PLOGI requests.
