Building Disaster Tolerant Serviceguard Solutions Using Metrocluster with Continuous Access XP
Files for Integrating XP Disk Arrays with Serviceguard Clusters
Chapter 3 155
Metrocluster/Continuous Access needs to be installed on all nodes that
will run a Serviceguard package whose data are on an HP StorageWorks
Disk Array XP Series, and where the data is replicated to a second XP
using the Continuous Access XP facility. In the event of node failure, the
integration of Metrocluster/Continuous Access with the package will
allow the application to fail over in the following ways:
• among local host systems attached to the same XP Series array
• between one system that is attached locally to its XP and
another “remote” host that is attached locally to the other XP
Configuration of Metrocluster/Continuous Access must be done on all the
cluster nodes, as is done for any other Serviceguard package. To use
Metrocluster/Continuous Access, Raid Manager XP host-based software
for control and status of the XP Series boxes must also be installed and
configured on each HP 9000 or Integrity host system that might execute
the application package.
