Operating Systems AIX Crash dump and Panic message : RSCT Dead Man Switch Timeout for HACMP; halting non-responsive node Post 303042285 by rbatte1 on Friday 20th of December 2019 06:36:11 AM

Could this be that whatever is supplying the common disk used to keep heartbeat failed? That way, both nodes would be unable to keep updating the shared disk and the usual response is to terminate all services to avoid getting in the way, i.e. to panic/abort. We've had a Oracle RAC database cluster do this before. not pretty, but it is the best course of action to avoid damage.

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
cmruncl was developed by HP. SEE ALSO
