HP 3PAR Replication Adapter 4.0.1 for VMware Site Recovery Manager Implementation Guide
10.0 Failover
Failover is a process within the VMware vCenter Site Recovery Manager and occurs when a
protected site virtual infrastructure is replicated to the recovery site. The HP 3PAR Storage
System has Remote Copy Primary role at the protected site and Remote Copy Secondary role at
the recovery site in an event of a failover.
Failover is planned in advance by the following:
■ Identifying replicated datastores and RDMs between two HP 3PAR Storage System array
managers and VMs residing on the replicated datastores.
■ Inventory mapping resources (e.g. Networks, Computer Resources, Virtual Machine Folders)
between the protected and the recovery sites.
■ Creating a protection group for VMs at the protected site.
■ Creating a failover recovery plan at the recovery site for the protection group at the
protected site.
The failover plan is tested at the recovery site to ensure the protected site’s virtual
infrastructure replicable at the time of disaster. The HP 3PAR Replication Adapter creates read-
write snapshots of all replicated volume in a failover recovery plan and delivers the snapshots
to the recovery site ESX host(s).
