HP Serviceguard Metrocluster with EMC SRDF for Linux B.01.00.00

Application Detach (LAD)) allows you to do this kind of maintenance while keeping the packages
running. The packages are no longer monitored by Serviceguard, but the applications continue
to run. Packages in this state are called detached packages. When you have done the necessary
maintenance, you can restart the node or cluster, and normal monitoring will resume on the
packages. For more information on the LAD feature, see Managing HP Serviceguard A.11.20.20
for Linux available at http://www.hp.com/go/linux-serviceguard-docs → HP Serviceguard.
Checking the Metrocluster package configuration
Starting HP Serviceguard version A.11.20, the cmcheckconf -v command validates the cluster
and the package configuration. HP recommends that you set up a cron job to regularly run the
cmcheckconf command. For more information about setting the cron job, see Setting up Periodic
Cluster Verification section in the latest version of the Managing Serviceguard manual available
at http://www.hp.com/go/linux-serviceguard-docs →HP Serviceguard.
“Validating Metrocluster package” (page 30) lists the checks made on a Metrocluster Package.
