Managing HP Serviceguard A.12.00.00 for Linux, June 2014
start command from one of the nodes on a cluster to start the cluster analytics daemon. Cluster
Analytics daemon gets started only in cluster coordinator node. For example, #cmcaadmin start
• If the cluster is not configured, then cmcaadmin start command displays the following
message:
cmcaadmin: Starting Cluster Analytics daemon based on entries in $SGCONF/cmclnodelist
cmcaadmin: Started Cluster Analytics daemon successfully on node test1
• If the cluster is configured and down, then cmcaadmin start command displays the following
message:
cmcaadmin: Starting Cluster Analytics daemon on node test1
cmcaadmin: Started Cluster Analytics daemon successfully on node test1
• If the cluster is configured and up, then cmcaadmin start command displays the following
message:
cmcaadmin: Starting Cluster Analytics daemon on cluster coordinator test1
cmcaadmin: Started Cluster Analytics daemon successfully on node test1
NOTE: If the cluster is not configured, ensure that the nodes which are to be configured in the
cluster are present in the $SGCONF/cmclnodelist file. If $SGCONF/cmclnodelist file does
not exist, then Cluster Analytics daemon starts on node from which cmcaadmin startcommand
has been issued.
9.2.1 Cluster Event Message Consolidation
The cluster analytics daemon process performs the following operations related to the database
as part of its initialization sequence and uses the database for consolidation of all cluster event
messages:
• Opens an existing $SGCONF/cluster.db3 database file if the cluster and database file is
already present on the system.
• Creates a new database file, if the cluster is configured or running and its analytics database
file is not created earlier.
• Performs the backup of an existing database file if any change in the cluster name is detected
and creates a new database file by appending current date and time.
9.3 Stopping Cluster Analytics Daemon
Use cmcaadmin stop command to stop the cluster analytics daemon. For example, #cmcaadmin
stop
• If the cluster is not configured, then cmcaadmin stop command displays the following
message:
cmcaadmin: Stopping Cluster Analytics daemon based on entries in $SGCONF/cmclnodelist
cmcaadmin: Stopped Cluster Analytics daemon successfully on node test1
• If the cluster is configured and down, then cmcaadmin stop command displays the following
message:
cmcaadmin: Stopping Cluster Analytics daemon on node test1
cmcaadmin: Stopped Cluster Analytics daemon successfully on node test1
• If the cluster is configured and up, then cmcaadmin stop command displays the following
message:
cmcaadmin: Stopping Cluster Analytics daemon on cluster coordinator test1
cmcaadmin: Stopped Cluster Analytics daemon successfully on node test1
