Using vSphere HA
You can set up VM level high availability using the following steps:
- Turn on vSphere HA or the vSphere Cluster that the RCA-V is deployed on.
- Turn on Enable Host Monitoring and VM Monitoring in vSphere HA configuration.
This will enable monitoring at two different levels:
- If the host goes down, the RCA-V VM on that host will automatically restart on another host that is healthy.
- If the VM running RCA-V goes down due to an accidental power-off or the guest OS crashing, the RCA-V will restart on the same physical server.
Using Standby RCA-V
Have another RCA-V pre-configured and ready to go in case the primary RCA-V fails.
The procedure for creating a secondary RCA-V is:
a. Deploy another instance of RCA-V (called RCA-V-DR)
b. Login to the admin UI for RCA-V-DR and configure the vSphere connectivity section.
c. Copy the following files from primary RCA-V into RCA-V-DR
d. Power off RCA-V-DR. In case of failure of RCA-V primary, the RCA-V-DR is ready to get started and taking on requests from RS platform.
