>This chapter discusses how to configure cluster storage containers (referred to throughout

this chapter as "cluster containers"), a feature provided by the EVMS Cluster Segment
|
|
Manager (CSM).</P

|
><P
|
|
>Disks that are physically accessible from all of the nodes of the cluster can be
|
|
grouped together as a single manageable entity. EVMS storage objects can then be
|
|
created using storage from these containers.</P

|
|
>Ownership is assigned to a container to make the container either private or shared.
|
|
A container that is owned by any one node of the cluster is called a private container.
|
|
EVMS storage objects and storage volumes created using space from a private
|
|
container are accessible from only the owning node.</P
|
|
><P
|
|
>A container that is owned by all the nodes in a cluster is called a shared container.
|
|
EVMS storage objects and storage volumes created using space from a shared
|
|
container are accessible from all nodes of the cluster simultaneously.</P
|
|
><P
|
|
>EVMS provides the tools to convert a private container to a shared container, and
|
|
a shared container to a private container. EVMS also provides the flexibility to
|
|
change the ownership of a private container from one cluster node to another
|
|
cluster node.</P
