- In order to failover to an associated cluster, a SyncIQ policy must exist between the source and target cluster, as explained in Configuring a SyncIQ policy.
- If the policy is configured, it must have successfully run at least once.
- All system configuration is complete on the target cluster, emulating the source cluster’s configuration. This includes licensing, access zones, SmartConnect, shares, authentication providers, etc.
- This section does not consider any network or other environmental changes required. During disaster readiness testing, ensure that all other environmental steps are documented and shared with administrators.
Note: As a best practice, configure DNS to require a single forwarding change only. During an outage, this minimizes downtime and simplifies the failover process.
