                                                                      VCS bundled agents for UNIX


                            Table 6-1     Storage agents and their description (continued)

                             Agent         Description
                             DiskGroup     Brings Veritas Volume Manager (VxVM) disk groups online and offline,
                                           monitors them, and make them highly available. The DiskGroup agent
                                           supports both IMF-based monitoring and traditional poll-based
                                           monitoring.
                                           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.
                   4.7.9     Mount         Brings resources online and offline, monitors file system or NFS client
                                           mount points, and make them highly available. The Mount agent
                                           supports both IMF-based monitoring and traditional poll-based
                                           monitoring.
                                           The Mount agent can be used with the DiskGroup and Volume agents
                                           to provide storage to an application.
                                           See “About resource monitoring” on page 38.
                             Zpool         Brings online, takes offline, and monitors ZFS storage pools.


   4.7.9  About Network agents
                            Network agents monitor network resources and make your IP addresses and
                            computer names highly available. Network agents support both IPv4 and IPv6
                            addresses. However, you cannot use the two types of addresses concurrently.
                            Table 6-2 shows the Network agents and their description.
