Description These release notes contain information about installing, operating, and maintaining the HP StorageWorks Multi-protocol (MP) router running XPath OS 7.4.1e. Supersedes history This version supersedes XPath OS 7.4.1d released in March 2007. Effective date August 2007 Update recommendation Routine Product compatibility Table 1 lists compatible HP MP Routers and transceivers.

Fixes Table 3 lists critical or high level issues resolved in XPath OS 7.4.1e firmware. Table 3 Resolved issues in XPath OS 7.4.1e firmware Issue Description Zone segmentation in edge fabric can cause an established IFL to be disabled and the newly formed IFL to connect. Zone segmentation in edge fabric can cause an established IFL to be disabled and the newly formed IFL to connect. In disabling a switch with an attached IFL, change the zone cfg and then enable the switch.
IMPORTANT: U_Port/E_Port connections are supported between two or more routers only for the purpose of creating a router backbone fabric. If an E_Port connection is made from an MP Router to an edge fabric, you must remove the edge fabric configuration and zone settings from the router as the edge fabric configurations and zone settings would propagate to the router when connected. You must use the EX_Port type when connecting edge fabrics to an MP Router.
Table 6 Fibre Channel routing services 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.
Issue Description • Manually enable any disabled EX_Ports when the condition occurs. Edge fabric segmentation If an edge fabric in which multiple EX_Ports are linked to multiple edge switches segments into two or more fabrics, all EX_Ports connected to any of the new fabrics resulting from the segmentation will be disabled due to a fabric ID (FID) conflict error. If the edge fabric remerges into a single fabric, the EX_Ports that were disabled remain disabled until administratively enabled.
Issue Description Due to the various link-encapsulation methods, header sizes, and so forth, it might be difficult to determine the exact available bandwidth for a particular link. HP recommends setting the bandwidth parameter to 96% of the advertised link bandwidth (for example, -b 96 for a 100 Mbps link). Additional tuning of the bandwidth parameter might be necessary for optimal throughput. Jumbo Frame Support.
Issue Description Where 10 represents the edge fabric ID, 20 is Remote fabric ID and 30 is the preferred xlate domain ID. Use the help command for more details on the fcrxlateconfig command. Password length is limited to 8 characters. For XPath OS 7.4.x, the maximum password length is 8 characters. FTP servers XPath OS supports downloading firmware from any FTP server that is RFC FTP compliant. Limited testing has been completed against the following FTP servers: • HP-UX • RedHat Linux 8.
Issue Description If you are unable to use firmwareDownload to install the recovery kernel package, follow the product manual instructions to install the XPath Recover RPG through PMON. After you have booted into the recovery kernel, enter the shell by entering shell at the rash prompt. Run the nvclean utility and answer yes when it prompts you. This will rectify any NVRAM corruption that might exist.
Issue Description • Existing versions of Fabric Manager and other API-based applications that manage zoning in edge fabrics can 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 date. • A FAL-based application connected to a Fabric OS v2.
Table 11 Fabric Manager Issue Description Disabled EX_Port If an EX_Port is disabled due to a Fabric ID conflict, the reason (Fabric ID conflict) is not displayed in the “Type” column of the Ports Table within Fabric Manager. Front and Xlate Domains The Front and Xlate Domains are listed in the “Selected Fabric” tree of the FCS tab within the Secure Policy Editor in Fabric Manager. These domains should not be listed. If these domains are selected and added to the FCS list, an error message is received.
XPath OS migration procedures The XPath OS migration procedures are described in the HP StorageWorks XPath OS administrator guide.
