3 – Planning Recovery

S

Recovery

It is prudent to 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, because you may:

„Want to revert to a previous firmware version

„Need the firmware image when replacing a router

„Need the firmware image when adding a router to your site

„Save the router’s configuration (as a new file) after every configuration change, because you may:

„Want to revert to a previous configuration

„Need to configure a replacement router

„Save the router’s LUN mappings (as a new file) after every mapping change, because you may:

„Want to revert to a previous LUN mapping

„Need to LUN-map a replacement router

„Want to duplicate the LUN mapping on a second router (for redundancy)

Services

You can configure your router to suit the demands of your environment using a variety of router services. Familiarize yourself with the following router services and determine which ones you need:

„Telnet – Enables you to manage the router over a telnet connection.

„Router management – Provides for out-of-band management of the router with the SANsurfer Router Manager.

„Simple network management protocol (SNMP) – Enables you to monitor the router using third-party applications that use SNMP.

„Network time protocol (NTP) – Enables you to synchronize the router and the workstation dates and times with an NTP server. NTP is disabled (not configured) by default.

„File transfer protocol (FTP) – Enables you to transfer files rapidly between the workstation and router using FTP.
