cmhaltcl - halt a high availability cluster SYNOPSIS
cmhaltcl [-f] [-v] DESCRIPTION
cmhaltcl causes all nodes in a configured cluster to stop their cluster daemons, optionally halting all packages or applications in the process. To stop 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(1). This command will halt all the daemons on all currently running systems. If the user only wants to shutdown a subset of daemons, the cmhaltnode command should be used instead. Options cmhaltcl supports the following options: -f Force the cluster to shutdown even if packages or group members are currently running. This will cause the packages and group members to be halted. If a package halt fails, the cluster halt will also fail. -v Verbose output will be displayed. RETURN VALUE
cmhaltcl returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
Halt the cluster daemons: cmhaltcl AUTHOR
cmhaltcl was developed by HP. SEE ALSO
cmquerycl(1m), cmhaltnode(1m), cmruncl(1m), cmrunnode(1m), cmviewcl(1m). Requires Optional Serviceguard Software cmhaltcl(1m)
