Chapter 8. MetroCluster 123
8.7.4 MetroCluster site failure
In this scenario, a site disaster occurred and all switches, storage systems, and hosts are lost,
as shown in Figure 8-17. To continue data access, a cluster failover must be started by using
the cfo -d command. Both primaries now exist at data center 2, and hosting of Host1 is done
at data center 2.
Figure 8-17 Site failure
Attention: If the site failure is staggered in nature and the interconnect fails before the rest
of the site, data loss might occur. Data loss occurs because processing continues after the
interconnect fails. However, site failures often occur pervasively and at the same time.
