Requirements

Hardware Requirements

The hardware consists of multiported arrays, like the XP family or 12H, connected to multiple computers

where each port has access to the drives on the other port.

Limitations

implementor must script these features.

NOTE The Heartbeat facility is no guarantee that the primary system is down. Care must be

exercised in developing job scripts to cause a switchover to the secondary computer.

• Cluster/iX is not supported with path failover for the first release.
