Support for Device Group Monitor
Metrocluster with Continuous Access XP P9000 for Linux products supports Device Group Monitor
(DGM). DGM provides the capability to monitor the status of the Continuous Access device groups
configured in a Metrocluster package, from the node where the package is running.
Device Group Monitor provides the following functionalities:
• Sends a notification message upon the change in a device group status.
• Performs automatic resynchronization of the Continuous Access device group upon link
recovery.
For more information on Device Group Monitor in a Metrocluster Solution, see Building Disaster
Recovery Serviceguard Solutions Using Metrocluster with Continuous Access XP P9000 for Linux
available at http://www.hp.com/go/linux-serviceguard-docs.
Support for Data Replication Storage Failover Preview
The cmdrprev command enables you to preview the preparation process for data replication in
a Metrocluster environment and also helps you in identifying any potential problems in the data
replication environment, which if left undetected, may result in an unsuccessful Metrocluster failover.
For more information on using the cmdrprev command in your Metrocluster environment, see

command device. Using a remote array RAID manager instance, it is possible to get the status of
the device group on the remote P9000 array even when the remote hosts are inaccessible.
