Using Multiple Cluster Vips When Connecting To A Multi-Site San; Multi-Site San Vips With Mpio - HP StorageWorks P4000 User Manual

• For proper failover/failback configuration of a Multi-Site SAN you must configure all cluster VIPs
for discovery. List the VIPs in the preferred order of connection. For example, if Site A is the first
preference for connection, put the VIP associated to Site A first in the discovery list.
• You must also log on to the volumes with the default Target Portal setting.

Using multiple cluster VIPs when connecting to a Multi-Site SAN

Use the Virtual IP address of the HP P4000 SAN Solution cluster when connecting to volumes using
MPIO. In a Multi-Site SAN, you must enter the VIPs of all the multi-site clusters on all the application
servers to take advantage of the DSM's multi-path I/O capabilities. In addition, all the application
servers must have the VIPs listed in the same order.
A sample Multi-Site SAN configuration is shown. In this configuration, the cluster has three sites: Site
A, Site B, and Site C. Site A is primary.
