Figure 2 Example of alternate path configuration
Figure 3
shows another example of an alternate path configuration. In Figure 3 , two ports are specified
in the local array and connected to ports in the external array via switches. In this example, two ports
from different XP12000/XP10000/SVS200 clusters are specified in the local array, thereby making it
possible to configure an alternate path for high availability.
Figure 3 Example of alternate path configuration using two switches
In Figure 4 , two paths are configured between the internal LDEV and external LU. However, only one port
is specified in the local array and two ports are specified in the external arrays via the switch. Since
two ports of different clusters must be set in the local array for External Storage XP to use alternate path
settings, HP does not recommend the configuration shown in Figure 4 .
