What are the main steps in a NetApp DR drill using SnapMirror?

• A. Verify replication is current, perform a test failover/failback, validate data integrity, and update DR runbooks.
• B. Take a snapshot of all volumes and stop replication.
• C. Fail over without verification and ignore runbooks.
• D. Schedule backups weekly.

Answer: (A)

The main idea is practicing a disaster recovery drill with SnapMirror in a controlled way to prove readiness. You start by making sure replication is current, so you’re testing with the latest replica data and not with stale information. Then you perform a test failover and back (failover to the DR site and, if needed, failback to the primary) to validate that the switch over and restore processes work without disrupting production data in the long term. After the failover, you verify data integrity to confirm that replicated data matches the source and that applications can access and use the data as expected. Finally, you update the DR runbooks to reflect what happened during the drill, capture any gaps, and adjust procedures for future exercises. This sequence ensures the DR plan is actionable, repeatable, and keeps documentation current.

The other options don’t fit a DR drill: simply taking snapshots and stopping replication doesn’t test failover or verify ongoing data integrity; failing over without verification is unsafe and incomplete; and scheduling backups weekly describes general protection rather than a full, practiced DR drill with SnapMirror and runbook updates.
