Requesting node status and discovering the master node
The vxdctl utility controls the operation of the vxconfigd volume configuration daemon. The -c option can be used to request cluster information and to find out which node is the master. To determine whether the vxconfigd daemon is enabled and/or running, use the following command:
# vxdctl -c mode
This produces different output messages depending on the current status of the cluster node:
|
Status message
|
Description
|
|---|
mode: enabled: cluster active - MASTER
master: mozart
|

|
mode: enabled: cluster active - SLAVE
master: mozart
|
The node is a slave.
|
mode: enabled: cluster active - role not set
master: mozart
state: joining
reconfig: master update
|
The node has not yet been assigned a role, and is in the process of joining the cluster.
|
mode: enabled: cluster active - SLAVE
master: mozart
state: joining
|
The node is configured as a slave, and is in the process of joining the cluster.
|
mode: enabled: cluster inactive
|
The cluster is not active.

Note
If the vxconfigd daemon is disabled, no cluster information is displayed.
See the vxdctl(1M) manual page for more information.
