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.

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME
mkqdisk - Cluster Quorum Disk Utility WARNING
Use of this command can cause the cluster to malfunction. SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]] DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node. OPTIONS
-c device -l label Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough space to hold a UUID created with uuidgen(1). -f label Find the cluster quorum disk with the given label and display information about it. -L Display information on all accessible cluster quorum disks. -d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect. SEE ALSO
