Description These release notes contain information about installing, operating, and maintaining the HP StorageWorks Multi-protocol (MP) Router running XPath OS 7.4.1f. Supersedes history This version supersedes XPath OS 7.4.1e released in August 2007. Effective date November 2009 Update recommendation Routine Product compatibility Table 1 lists compatible HP MP Routers and transceivers.
Accessing the latest firmware To access XPath OS 7.4.1f firmware, configuration files, and MIB files, visit the following HP web site: http://h18006.www1.hp.com/storage/saninfrastructure/index.html Products supported For the latest product support information, see the Single Point of Connectivity Knowledge (SPOCK) on the HP website: http://www.hp.com/storage/spock. You must sign up for an HP Passport to access this website. Operating systems This product supports the following operating systems.
Installation This section describes HP MP Router installation issues. Migration procedure For instructions on migrating to XPath OS 7.4.1f from earlier versions of XPath OS, see the HP StorageWorks XPath OS 7.4.x Administrator Guide. Initial MP Router setup rules When an MP Router is powered on for the first time, all ports are disabled by default. You must explicitly set each MP Router port to the desired port type before making any cable connections.
Setting up and enabling the MP Router ports for the first time To set and enable MP Router ports: 1. Stop all ports using the following CLI command: > PORTSTOP 0-15 where 0-15 represents all ports on the router. This step ensures that it is now safe to cable other routers and/or edge fabrics to the router until such time that the user is ready to restart the port to complete the configuration. 2.
Important notes Table 5 through Table 10 list issues to consider when using XPath OS 7.4.1f and the HP StorageWorks MP Router. Table 5 Fibre Channel routing services Issue Unexpected LSAN Zone Update messages or unexpected physical device offline messages Description These messages can occur during normal operation.
Issue Description Certain configuration values and versions of Fabric OS switches in edge fabrics might cause EX_Ports on the Router to be disabled when the switches are rebooted. Evidence of the unexpected disabled EX_Port can be seen in the Router's port display: # switchshow Edge fabric switch booting and EX_Ports : 7 id AN No_Light disabled EX_PORT (Last error: Failed to init in time) Workaround for switches running FOS 3.x /4.
Issue Description FCIP and firewalls The MP Router uses XPP as the transport layer for FCIP transmission. When a firewall is in the path of the FCIP tunnel, the firewall must be configured to allow protocol type 206 in the IP header. The purpose of this protocol type is to establish a connection and enable the FCIP traffic that traverses the firewall. The FCIP selective acknowledgement feature was added in a previous version of firmware.
iSCSI Gateway Service support The MP Router provides iSCSI support enabling iSCSI initiators to access Fibre Channel-based storage subsystems. For the latest information on supported configurations limitations, see the HP StorageWorks SAN Design Reference Guide: http://h18000.www1.hp.com/products/storageworks/san/ documentation.html iSCSI Multi-path iSCSI configurations using the MP Router are not supported with multi-path software.
Issue Description Root reboot command vs. admin user reboot command Users should never reboot the system from the root account using the reboot command, or data might be lost. To safely reboot the system, log in as root and change to admin by entering admin at the root prompt. When you are at the admin shell, execute the reboot command. FA zoning A private host attached to a Fabric OS switch might not be able to discover FA targets on a MP Router due to the length of the host's HBA PLOGI retry timeout.
Issue Description The HP StorageWorks MP Router with XPath OS 7.4.0 includes licenses for the following features: • Advanced Web Tools Bundled licenses • Advanced Zoning • FCIP Tunneling • FC-FC Routing Different models of the MP Router ship with either 8 or 16 ports enabled. If you require an upgrade from 8 to 16 ports, contact your sales representative. SFP media support The MP Router supports only qualified SFP media. Run the sfpSupport command for a list of the qualified SFPs.
Issue Description Security Updates to Xpath OS 7.3.0 included openSSH version 3.8.1 to minimize security vulnerabilities of fabrics. The MP Router implementation of SSH has been modified to restrict use of SSH v1. SSH v1 may no longer be used to connect to the MP Router, but SSH v2 can be used instead. Table 9 Limitations Issue Description HP strongly encourages users of this release to do the following: • Manage the MP Router's functions using the MP Router's CLI and Advanced Web Tools.
Issue Description 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.
