NAME
cmhaltnode - halt a node in a high availability cluster SYNOPSIS
cmhaltnode [-f] [-v] [-t] [node_name...] DESCRIPTION
cmhaltnode causes a node to halt its cluster daemon and remove itself from the existing cluster. To halt cluster on the node, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configu- ration file. See access policy in cmquerycl. When cmhaltnode is run on a node, the cluster daemon is halted and, optionally, all packages that were running on that node are moved to other nodes if possible. If node_name is not specified, the cluster daemon running on the local node will be halted and removed from the existing cluster. If you issue this command while a cluster is still in the process of forming, the command will fail with the message "Unable to connect to daemon." If this happens, wait for the cluster to form successfully, then issue the command again. Options cmhaltnode supports the following options: -f Force the node to halt even if there are packages or group members running on it. The group members on the node will be terminated. The halt scripts for all packages running on the node will be run; based on priority or dependency relation- ships, this may affect packages on other nodes. In other words, packages on other nodes may either start or halt based on this package halting. If the package configuration and current cluster membership permit, and if the package halt script succeeds, the packages will be started on other nodes. Without this option, if packages are running on the given node, the command will fail. If a package fails to halt, the node halt will also fail. -v Verbose output will be displayed. -t Test only. Provide an assessment of the package placement without affecting the current state of the nodes or packages. This option validates the node's eligibility with respect to the package dependencies as well as the external dependencies such as EMS resources, package subnets, and storage before predicting any package placement decisions. If there is a pack- age in maintenance mode running on the nodes being halted, the package will always be halted and not failover to another node; the report will not display an assessment for that package. node_name... The name of the node(s) to halt. RETURN VALUE
cmhaltnode returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
Halt the cluster daemon on two other nodes: cmhaltnode node2 node3 AUTHOR

NAME
cmruncl - run a high availability cluster SYNOPSIS
cmruncl [-f] [-v] [-n node_name...] [-t | -w none] DESCRIPTION
cmruncl causes all nodes in a configured cluster or all nodes specified to start their cluster daemons and form a new cluster. To start a cluster, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configuration file. See access policy in cmquerycl(1m). This command should only be run when the cluster is not active on any of the configured nodes. This command verifies the network configu- ration before causing the nodes to start their cluster daemons. If a cluster is already running on a subset of the nodes, the cmrunnode command should be used to start the remaining nodes and force them to join the existing cluster. If node_name is not specified, the cluster daemons will be started on all the nodes in the cluster. All nodes in the cluster must be available for the cluster to start unless a subset of nodes is specified. Options cmruncl supports the following options: -f Force cluster startup without warning message and continuation prompt that are printed with the -n option. -v Verbose output will be displayed. -t Test only. Provide an assessment of the package placement without affecting the current state of the nodes or packages. The -w option is not required with the -t option as -t does not validate network connectivity, but assumes that all the nodes can meet any external dependencies such as EMS resources, package subnets, and storage. -n node_name... Start the cluster daemon on the specified subset of node(s). -w none By default network probing is performed to check that the network connectivity is the same as when the cluster was config- ured. Any anomalies are reported before the cluster daemons are started. The -w none option disables this probing. The option should only be used if this network configuration is known to be correct from a recent check. RETURN VALUE cmruncl returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
Run the cluster daemon: cmruncl Run the cluster daemons on node1 and node2: cmruncl -n node1 -n node2 AUTHOR
