Administering Cluster Functionality

Cluster Initialization and Conﬁguration

Chapter 10352

Different actions are taken depending on which node the vxconfigd

daemon is stopped:

• If the vxconfigd daemon is stopped on the master node, the

vxconfigd daemons on the slave nodes periodically attempt to rejoin

to the master node. Such attempts do not succeed until the

vxconfigd daemon is restarted on the master. In this case, the

vxconfigd daemons on the slave nodes have not lost information

about the shared conﬁguration, so that any displayed conﬁguration

information is correct.

• If the vxconfigd daemon is stopped on a slave node, the master node

takes no action. When the vxconfigd daemon is restarted on the

slave, the slave vxconfigd daemon attempts to reconnect to the

master daemon and to re-acquire the information about the shared

conﬁguration. (Neither the kernel view of the shared conﬁguration

nor access to shared disks is affected.) Until the vxconfigd daemon

on the slave node has successfully reconnected to the vxconfigd

daemon on the master node, it has very little information about the

shared conﬁguration and any attempts to display or modify the

shared conﬁguration can fail. For example, shared disk groups listed

using the vxdg list command are marked as disabled; when the

rejoin completes successfully, they are marked as enabled.

• If the vxconfigd daemon is stopped on both the master and slave

nodes, the slave nodes do not display accurate conﬁguration

information until vxconfigd is restarted on the master and slave

nodes, and the daemons have reconnected.

If the vxclustd daemon determines that the vxconfigd daemon is not

running on a node during a cluster reconﬁguration, vxclustd restarts

vxconfigd automatically.

NOTE The -r reset option to vxconfigd restarts the vxconfigd daemon and

recreates all states from scratch. This option cannot be used to restart

vxconfigd while a node is joined to a cluster because it causes cluster

information to be discarded.
