High Availability (Ha); Patch Flash://Runtime_Patch_Dir - Dell Force10 S4810P Reference Manual

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).

Usage
The patch filename includes the FTOS version, the platform, the CPU, and the process it affects
Information
(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.
