Failure of the vucmmd Daemon to Start

The multiple-owner volume-manager framework daemon, vucmmd, manages the reconfiguration of the multiple-owner volume-manager framework. When a cluster is booted or rebooted, this daemon is started only after all components of the multiple-owner volume-manager framework are validated. If the validation of a component on a node fails, the vucmmd daemon fails to start on the node.

The most common causes of this problem are as follows:

• An error occurred during a previous reconfiguration of a component of the multiple-owner volume-manager framework.

• A step in a previous reconfiguration of the multiple-owner volume-manager framework timed out, causing the node on which the timeout occurred to panic.
