23 Dell EMC SC Series: Disaster Recovery for Microsoft SQL Server Using VMware Site Recovery Manager | CML1018
If the primary site is still available, SRM will effectively perform a planned migration. SRM will power off the
virtual machines at the primary site, create new crash consistent snapshots, and recover the volumes from
those snapshots once they have been replicated to the recovery site. This will provide a failover with no data
loss. Since the recovery from crash consistent snapshots is different than the recovery from Replay Manager
snapshots, any recovery plans using Replay Manager snapshots also need to accommodate crash consistent
snapshots.
After SRM completes the recovery, additional setup or reconfiguration may be needed for systems that
cannot be managed by SRM. For example, things like tape backups or Replay Manager may need to be
reconfigured in order to function correctly at the recovery site.
4.7 Performing a planned migration
SRM can also be used to move virtual machines from one site to another. This type of recovery functions the
same as a disaster recovery. However, both sites must be online and available for the migration to succeed.
To perform a planned migration, perform the following:
1. In the vSphere web client, open the SRM plug-in.
2. On the left side of the client, double-click Recovery Plans.
3. Under the Objects tab, select the recovery plan that needs to be run.
4. Under the Actions drop-down menu (or the red circle with white arrow icon), select Run.
5. In the Recovery Confirmation pane, check the box I understand that this process will
permanently alter the virtual machines and infrastructure of both the protected and recovery
datacenters.
6. In the Recovery Type pane, select the Planned Migration option.
7. Click Next.
8. Click Start.
9. If there are multiple recovery plans, repeat the process for each recovery plan.
A planned migration will power off the virtual machines at the primary site, create new crash consistent
snapshots, and recover the volumes from those snapshots once they have been replicated to the recovery
site. This will provide a failover with no data loss. Since the recovery from crash consistent snapshots is
different than the recovery from Replay Manager snapshots, any recovery plans using Replay Manager
snapshots also need to accommodate crash consistent snapshots.
After SRM completes the recovery, additional setup or reconfiguration may be needed for systems that
cannot be managed by SRM. For example, tape backups or Replay Manager may need to be reconfigured in
order to function correctly at the recovery site.
