The cluster(1CL) command includes checks that examine the /etc/vfstab file for configuration errors with the cluster file system and its global mount points.
Run cluster check after making cluster configuration changes that have affected devices or volume management components.
Become superuser on an active member node of a global cluster. Perform all steps of this procedure from a node of the global cluster.

Verify the global cluster configuration.
phys-schost# cluster check |
The following example shows the node phys-schost-2 of the cluster named suncluster minus the mount point /global/schost-1. Reports are being sent to the output directory, /var/cluster/logs/cluster_check/<timestamp>/.
