Table: Storage agents and their description
Agent
|
Description |
DiskGroup
|
Brings Veritas Volume Manager (VxVM) disk groups online and offline, monitors them, and make them highly available.
No dependencies exist for the DiskGroup resource.
|
DiskGroupSnap
|
Brings resources online and offline and monitors disk groups used for fire drill testing. The DiskGroupSnap agent enables you to verify the configuration integrity and data integrity in a Campus Cluster environment with VxVM stretch mirroring. The service group that contains the DiskGroupSnap agent resource has an offline local dependency on the application's service group. This is to ensure that the fire drill service group and the application service group are not online at the same site.
|
Volume
|
Makes Veritas Volume Manager(VxVM) Volumes highly available and enables you to bring the volumes online and offline, and monitor them. Volume resources depend on DiskGroup resources.
|
VolumeSet
|
Brings Veritas
Volume Manager (VxVM) volume sets online and offline, and monitors them. Use the VolumeSet agent to make a volume set highly
available. VolumeSet resources depend on DiskGroup resources. |
LVMVG
|
Activates, deactivates, and monitors a Logical Volume
Manager (LVM) volume group. The LVMVG agent supports JFS or JFS2. It does
not support VxFS. This agent ensures that the Object Data Manager (ODM) is synchronized with changes to
the volume group. No dependencies exist for the LVMVG resource.
|
Mount
|
Brings resources online and offline, monitors file system or NFS client mount points, and make them highly available. The Mount agent can be used with the DiskGroup, LVMVG, and Volume agents to provide storage to an application. The Mount agent supports both IMF-based monitoring and traditional poll-based monitoring.
