2–PlanningHigh AvailabilityHigh AvailabilityManagementRecoveryA dual-blade iSR6200 router supports high availability, which provides link-level,switch-level, and blade-level failure protection. To make this effective, you mustconnect the iSCSI hosts to both iSR6200 blades. For details, see “ConnectingiSCSI Hosts to the iSR6200” on page 4-16.SANsurfer Router Manager and the CLI run on a management workstation usedto configure, control, and maintain the router. Support platforms include Windows,Solaris, and Linux. The SANsurfer Router Manager utility is installed andexecuted on the workstation.The router supports the following management interfaces:• SANsurfer Router Manager is a graphical user interface (GUI) utility thatruns on a management workstation (see the iSR6200 Router ManagerUser’s Guide).• CLI is the command line interface that runs on the router; users can accessthe CLI by means of Telnet or the serial port (see the iSR6200 CLI User’sGuide).• SNMP provides router status, traps, and alerts (for details, see Appendix B).You should have a process in place to recover from a possible router failure.Consider the following when developing a recovery process for the router:• Save all firmware image files (updates) in a safe, well-known place, becauseyou may: Want to revert to a previous firmware version Need the firmware image when replacing a single-blade router Need the firmware image when adding a router to your site• Save the router’s configuration (as a new file) after every configurationchange, because you may: Want to revert to a previous configuration Need to configure a replacement blade in a single-blade router• Save the router’s LUN mappings (as a new file) after every mappingchange, because you may: Want to revert to a previous LUN mapping Need to LUN-map a replacement blade in a single-blade routerISR651101-00 G 2-7
