Administering VxVM in Cluster Environments
The following sections describe procedures for administering the cluster
functionality of VxVM.
NOTE Most VxVM commands require superuser or equivalent privileges.
Requesting the Status of a Cluster Node
The vxdctl utility controls the operation of the vxconfigd volume
configuration daemon. The -c option can be used to request cluster
information. To determine whether the vxconfigd daemon is enabled
and/or running, use the following command:
# vxdctl -c mode
This produces one of the following output messages depending on the
current status of the cluster node:
mode: enabled: cluster active - MASTER
mode: enabled: cluster active - SLAVE
mode: enabled: cluster active - role not set
mode: enabled: cluster inactive
NOTE If the vxconfigd daemon is disabled, no cluster information is displayed.
See the vxdctl(1M) manual page for more information.
Determining if a Disk is Shareable
The vxdisk utility manages VxVM disks. To use the vxdisk utility to
determine whether a disk is part of a cluster-shareable disk group, use
the following command:
# vxdisk list accessname
where accessname is the disk access name (or device name).
