6.3.1Fibre Channel Cluster Configurations for Transparent Failover Mode

With transparent failover mode:

•The hosts do not know a failover has taken place (failover is transparent to the hosts).

•The units are divided between an HSG80 port 1 and port 2.

•If there are dual-redundant HSG80 controllers, controller A port 1 and controller B port 2 are normally active; controller A port 1 and controller B port 1 are normally passive.

•If one controller fails, the other controller takes control and both its ports are active.

Figure 6–4 shows a typical Fibre Channel cluster configuration using transparent failover mode.
