HP ProLiant Cluster HA/F500 for MA8000 Enhanced DT Supplement Guide

Disaster Recovery
Refer to the DRM guide for detailed instructions about both planned and unplanned
failover procedures.
IMPORTANT: Do not reinstall MSCS. It is not necessary to reinstall the MSCS at the target
site after a site failover is performed in an HA/F500 Enhanced DT configuration.
Figure 3-3: Initiator site failover
The cluster nodes at the target site must be rebooted after you perform the site
failover procedures.
Initiator Site Failback
When a new initiator site has been established or the original site has been restored,
site operation can resume after a failback procedure has been performed. A failback
procedure involves synchronizing both the initiator and target storage subsystems so
that operation can be returned to the initiator with minimal downtime. Verify that all
components at both sites are operational before performing a failback.
