21 High Availability (HA) High availability (HA) in the Dell Force10 operating software (FTOS) is configuration synchronization to minimize recovery time in the event of a route processor module (RPM) failure. The feature is available on the C-Series, E-Series, S-Series, and S4810 platforms. High availability is supported on the S-Series S4810 with FTOS version 8.3.12.0 and on the E-Series ExaScale with FTOS version 8.1.1.0 and later. FTOS on the E-Series supports RPM 1 + 1 redundancy. The Primary RPM performs all routing and control operations, while the Secondary RPM is online and monitoring the Primary RPM. In general, a protocol is defined as "hitless" in the context of an RPM failure/failover and not failures of a line card, SFM, or power module. A protocol is defined as hitless if an RPM failover has no impact on the protocol. You must specifically enable some protocols for HA. Some protocols are only hitless if related protocols are also enabled as hitless (for example, the redundancy protocol command). patch flash://RUNTIME_PATCH_DIR Insert an In-Service Modular Hot-Fix patch. E-Series, S4810 Syntax Defaults Command Modes Command History Usage Information Related Commands patch flash://RUNTIME_PATCH_DIR/patch-filename To remove the patch, use the no patch flash://RUNTIME_PATCH_DIR/patchfilename command. none CONFIGURATION Version 8.3.12.0 Version 8.2.1.0 Introduced on the S4810. Introduced. The patch filename includes the FTOS version, the platform, the CPU, and the process it affects (FTOS-platform-cpu-process-patchversion.rtp). For example, a patch labeled "7.8.1.0-EH-rp2-l2mgr-1.rtp" identifies that this patch applies to FTOS version 7.8.1.0 - E-Series platform, for RP2, addressing the layer 2 management process, and this patch is the first version of this patch. There is no need to reload or reboot the system when you insert the patch. The In-Service Modular patch replaces the existing process code. After installation is complete, the system executes the patch code as though it was always there. show patch - displays the system patches loaded with the in-service modular hot fix command. 725
