Installing and Using EMS
Using EMS HA Monitors
Using EMS HA Monitors
There are two ways to use EMS HA Monitors:
•Configure monitoring requests from the EMS interface in the Resource Management area of SAM.
•Configure package dependencies in MC/ServiceGuard by using the Package Configuration interface in the High Availability Clusters subarea of SAM or by editing the package ASCII configuration file.
The following are prerequisites to using EMS:
•Disks need to be configured using the LVM (Logical Volume Manager).
•Network cards need to be configured.
•Filesystems need to have been created and mounted.
Resource classes are structured hierarchically, similar to a filesystem structure, although they are not actually files and directories. The classes supplied with this version of EMS are listed in Figure

The full path of a resource includes the class, subclasses, and instance. An example of a full resource path for the physical volume status of the device /dev/dsk/c0t1d2 belonging to volume group vgDataBase, would be /vg/vgDataBase/pv_pvlink/status/c0t1d2.
