Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Replica

In the rare case where the current primary site becomes inaccessible while data

is resynchronized from that site to the original primary site using the fast fail

back method, the administrator at the original primary site may resort to using

a data snapshot (if it exists) taken before the start of the fast fail back operation.

In this case, the failure type is designated as "replica".

Examples for takeover and resynchronization

The examples illustrate the steps required for an outage takeover and

resynchronization.

To take over after an outage

From any node of the secondary site, issue the haclus command:

# haclus -declare outage -clus rac_cluster101

After declaring the state of the remote cluster, bring the Oracle service group

online on the secondary site. For example:

# hagrp -online -force database_grp -any
