clusterconf Command

Purpose

clusterconf command is a service utility for administration of a CAA cluster configuration.

Syntax

clusterconf [ -r hdiskN] [-v]

Description

The clusterconf command will allow administration of the CAA cluster configuration.

If a node in a CAA cluster configuration is showing as DOWN (can be viewed from issuing the command “lscluster –m”) or a node in a CAA cluster is not showing up in the CAA cluster configuration and you know the node is part of the CAA cluster configuration (can be viewed from another node in the CAA cluster with “lscluster –m”) the following flags will allow the node to search and read the repository disk and take self-correcting actions.

Note: The clusterconf command is required to create a CAA cluster.
In addition, the inetd daemon must be running, and the line configuring the caa_cfg service must be uncommented in the /etc/inetd.conf file. This must be true on all nodes.

Flags

If no flags are specified the clusterconf command will perform a refresh operation by retrieving the CAA cluster repository configuration and performing the necessary actions. Actions which may occur are for a CAA cluster node to join a CAA cluster that the node is a member of and for some reason had been disconnected from the CAA cluster (either via network or SAN problems), a CAA cluster node may perform a resync with the CAA cluster repository configuration (again from some problems in the network or SAN) and the CAA cluster node may leave the CAA cluster configuration is the node had been removed from the CAA cluster repository configuration. The clusterconf command is a normal CAA cluster service and is automatically handled during normal operation.

Item Description
-r hdiskN If you know where the repository disk is (lspv and look for cvg) use this option to have the CAA cluster subsystem read the repository device and if this node is configured in the repository disk this command will cause the node to join the CAA cluster.
-v Specify verbose mode.

Examples

  1. To recover the CAA cluster configuration and start CAA cluster services:
    clusterconf –r hdisk1

Files

Item Description
/etc/inetd.conf Contains configuration information for the inetd daemon.
/usr/sbin/clusterconf Contains the clusterconf command.
