As a service group is brought online or taken offline, the resources within the group are brought online and taken offline. If the online or offline operation hangs on a particular resource, flush the service group to halt the operation on the resources waiting to go online or offline. Flushing a service group typically leaves the cluster in a partial state. After completing this process, resolve the issue with the particular resource (if necessary) and proceed with starting or stopping the service group.
To flush a service group on a system
hagrp -flush group -sys system [-clus cluster | -localclus]
To flush all service groups on a system
PATH=/opt/VRTSvcs/bin:$PATH; export PATH
echo "usage: $0 <system name>"
