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.
