High Availability
ISR651101-00 C 2-7
High Availability
A dual-blade iSR6200 router supports high availability, which provides link-level,
switch-level, and blade-level failure protection. To make this effective, you must
connect the iSCSI hosts to both iSR6200 blades. For details, see “Connecting
iSCSI Hosts to your iSR6200” on page 4-16.
Management
SANsurfer Router Manager and CLI run on a management workstation used to
configure, control, and maintain the router. Support platforms include Windows,
Solaris, and Linux. The SANsurfer Router Manager utility is installed and
executed on the workstation.
The router supports the following management interfaces:
SANsurfer Router Manager is a graphical user interface (GUI) utility that
runs on a management workstation (see the iSR6200 Router Manager
User's Guide).
CLI is the command line interface that runs on the router; users can access
the CLI by means of Telnet or the serial port (see the iSR6200 Router CLI
User's Guide).
SNMP provides router status, traps, and alerts (see Appendix B).
Recovery
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, because
you 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 routers configuration (as a new file) after every configuration
change, because you may:
Want to revert to a previous configuration.
Need to configure a replacement blade in a single-blade router.
Save the routers LUN mappings (as a new file) after every mapping
change, because you may:
Want to revert to a previous LUN mapping.
