3.7.6 Cluster Enabling Traditional Linux Volumes on Shared
Disks
Cluster enabling a traditional Linux volume allows it to be moved or mounted on different servers in
the cluster. This provides a way for clients to reconnect to the volume regardless of which server is
hosting it.
EVMS containers are the unit of failover for traditional Linux volumes. Because the EVMS
container is the unit of failover, all volumes in a container will also fail over, but only the volumes
that are mounted through the cluster resource load script will be mounted. Any volumes in the
container that are not mounted through the resource load script will have to be mounted manually.
The following sections contain information on cluster enabling a traditional Linux volume on a
shared disk partition:
“Creating a Traditional Linux Volume Cluster Resource” on page 37
“Configuring Traditonal Linux Volume Load Scripts” on page 37
“Configuring Traditional Linux Volume Unload Scripts” on page 39
