Operating Systems AIX Deactivating HACMP without deinstall Post 302816861 by MichaelFelt on Tuesday 4th of June 2013 05:24:44 PM

Assumption #1: no resource groups are active

If true, HACMP is not active so you can just remove the cluster.

Easiest way is to just go into smitty hacmp menu and find the option to remove the cluster. If I recall correctly - there is no need to syncronize because the cluster definition is removed - thus, the node has no idea how to syncronize.

Repeat this on each node.

Whether you delete the cluster.* filesets is an option. Once the cluster definition is removed the software is dormant.

Hope this helps!

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
