Chapter 3. Recovering multiple servers with replication


Restore an Identity Management (IdM) environment after a simultaneous loss of multiple replicas. Identify the correct recovery path based on your CA configuration and the operational status of the renewal server.

Rebuild an Identity Management (IdM) environment where all servers are considered equal due to the use of an external Certificate Authority (CA). In this scenario, you can rebuild the environment by removing and replacing lost replicas in any order.

Prerequisites

  • Your deployment uses an external Certificate Authority (CA).

Restore an Identity Management (IdM) environment where the CA renewal server is intact. Because the critical CA renewal server remains operational, you can recover the lost replicas by replacing them in any order.

Prerequisites

  • Your deployment uses the IdM internal Certificate Authority (CA).

Restore an Identity Management (IdM) environment when the server holding the CA renewal role is lost along with other replicas. In this scenario, you must first promote a functional CA server to the renewal role before rebuilding the rest of the environment.

Prerequisites

  • Your deployment uses the IdM internal Certificate Authority (CA).
  • At least one CA replica is unharmed.

Procedure

  1. Promote another CA replica to fulfill the CA renewal server role. See Recovering from losing the CA renewal server.
  2. Replace all other lost replicas. See Recovering from losing a regular replica.
