3.3 Unsupported and Illegal Cluster Configurations

Figure 3-5 shows a TruCluster Server configuration that is not supported.

The MSA1000 controllers operate in active/passive mode; one controller is

active while the other controller is passive. In the configuration shown in

Figure 3-5, both cluster member systems try to make their controller active,

creating a ping-pong effect. Both systems would receive many errors, and no

useful I/O would be accomplished.
