cmruncl(1m) cmruncl(1m) 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

cmscancl(1m) cmscancl(1m) NAME
cmscancl - gather system configuration information from nodes with Serviceguard installed. SYNOPSIS
cmscancl [-n node_name]... [-s|-o output_file] DESCRIPTION
cmscancl is a configuration report and diagnostic tool intended only for use by HP Support Personnel. It gathers system software and hard- ware configuration information from a list of nodes, or from all the nodes in a cluster. The information that this command displays includes LAN device configuration, network status and interfaces, file systems, LVM configuration, link-level connectivity (HPUX only), IPv4/IPv6 connectivity, and the data from the binary cluster configuration file. This command can be used as a troubleshooting tool or as a data collection tool. This command is a Perl script which gathers system configuration information by executing various OS commands or tools. It uses the cmexec command to gather information from remote nodes. The -n option can be used to specify a list of nodes to be scanned, the nodes to be scanned do not need to be a member of a cluster. If the -n option is not specified, it will scan all the nodes in the local cluster. By default, the output of this command will go to the file /tmp/scancl.out. If the file /tmp/scancl.out already exists, the old file will be saved in /tmp/scancl.out.old. The -o option can be used to redirect output to a specified output file. If the -o option is not specified, output will go to the default output file /tmp/scancl.out. The -s option can be used to direct all output to the screen, instead of to an output file. Options cmscancl supports the following options: -n node_name... Specify the node(s) to be scanned. If this option is not specified and there is a cluster configured, all the nodes in the cluster will be scanned. If this option is not specified and there is no cluster configured, only the local node will be scanned. -o output_file Write configuration information to a specified output file. If this option is not specified, the information will be directed to stdout. -s Display the configuration information to the screen only. This option cannot be used in conjunction with the -o option. The output from this command contains the following information: LAN device configuration (On HP-UX, output from lanscan; On Linux, output from ifconfig) network status and interfaces (output from netstat) file systems (output from mount) LVM configuration (contents of /etc/lvmtab file) LVM physical vg information (contents of /etc/lvmpvg file) link-level connectivity (HP-UX only) (output from linkloop) IPv4/IPv6 connectivity (results from ping (and ping6 on Linux)) binary configuration file data (output from cmviewconf) RETURN VALUE
cmscancl returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
To gather the configuration information from node1 and node2 and to save the output in file /tmp/scancl.log: cmscancl -n node1 -n node2 -o /tmp/myscancl.log To gather the configuration information from all the nodes in the cluster and save the output to the file: /tmp/scancl.log: cmscancl -o /tmp/myscancl.log To gather the configuration information from all the nodes in the cluster and display the output on the screen: cmscancl -s To gather the configuration information from all the nodes in the cluster and save the output to the file /tmp/scancl.out: cmscancl AUTHOR
