Administering VxVM in Cluster Environments
The following sections describe the administration of VxVM’s cluster functionality.
Note Most VxVM commands require superuser or equivalent privileges.
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:
Note If the vxconfigd daemon is disabled, no cluster information is displayed.
See the vxdctl(1M) manual page for more information.
