PRIMECLUSTER Wizard for NetWorker monitors a NetWorker process while PRIMECLUSTER is running. If the NetWorker daemons stop, this PRIMECLUSTER Wizard considers that a failure occurs in the system. Then, the NetWorker daemons are restarted or switched to the STANDBY node. If maintenance work is required, discontinue monitoring the NetWorker resource or use the maintenance mode of PRIMECLUSTER.
Discontinue monitoring the NetWorker resource
Execute the following commands to discontinue monitoring the NetWorker resource on the OPERATING node.
Discontinuing monitoring the resource
# /etc/opt/FJSVclntw/sbin/hvnwdisable application_name resource_name
Restarting monitoring the resource
# /etc/opt/FJSVclntw/sbin/hvnwenable application_name resource_name
The userApplication name is specified for application_name. The NetWorker resource name is specified for resource_name. Confirm the userApplication name and the resource name by using the hvdisp command of PRIMECLUSTER.
