Configure Metrocluster with Continuous Access for P9000 and XP Device Group Monitor for
Modular Packages
While using Modular style packages, the parameters used for configuring the Device Group Monitor
that were previously available in the Metrocluster environment file, are now available in the package
configuration file.
Complete the following procedure to configure the Device Group Monitor when using Modular
style packages:
1. Configure the parameters for the Device Group Monitor in the Metrocluster XPCA modular
package configuration file.
2. Un-comment the service parameters for the Device Group monitor and provide a unique name
to the service_name parameter.
Do not edit the service_cmd parameter. It is auto generated.
3. Run the following command to validate the package configuration file:
cmcheckconf -P temp.config
4. Run the following command to apply the package configuration file:
cmapplyconf -P temp.config
Configure Metrocluster with Continuous Access for P9000 and XP Device Group Monitor as a
Service of the Package
Add the monitor as a service in the package's configuration file and control script file as follows:
• In the package's configuration file, add the following lines:
SERVICE_NAME pkgXdevgrpmon.srv
SERVICE_FAIL_FAST_ENABLED NOSERVICE_HALT_TIMEOUT 5
NOTE: The SERVICE_HALT_TIMEOUT value of 5 is a recommended value. If the value is set
to lower than 5 seconds as the service halt timeout, then it may not allow enough time for the
monitor to properly clean itself up.
• In the package's control script file, add the following lines on the SERVICE NAMES AND
COMMANDS section:
SERVICE_NAME[0]=”pkgXdevgrpmon.srv”
SERVICE_CMD[0]=”/usr/sbin/DRMonitorXPCADevGrp <full path name of
the package environment file>”
SERVICE_RESTART[0]=”-r 10”
CAUTION: If the Continuous Access links are still down while the monitor is trying to do the
resynchronization and another failure occurs that causes a remote failover to the secondary site,
the SVOL’s BC volumes will remain split from its mirror group.
This will only occur if the monitor is configured to perform automatic resynchronization using
AUTO_RESYNC=1.
