SCSI reservation agents manage LUN based locking using the SCSI3-PR (Persistent Reservation) protocols that shared storages support such as SAN.
This function can prevent data losses when no nodes in a cluster know the status of other nodes.
Shared disk DR
The disk shared between the two nodes of MCCS is copied to a remote server, so that data can be safely protected from disasters.
A remote server has no MCCS installed in it. Thus, you need to establish an additional service recovery plan.
VxVM disk group
It It is used to manage a disk group of Veritas Windows Volume Manager.
The sub volumes of a disk group are not individually managed.
Oracle database
This resource controls the Oracle database.
It detects the Oracle database installed on the system, controls the service and monitors the status.
When you add a resource, this will be classified under the type as tree view structure.
For an example, when you add two NIC resource, these will be classified under the NIC type as shown below.
If you edit an attribute of resource type, this will affect all of the resources classified this type.
...
As shown in the figure, public and private 1 are the resources included in the NIC resource type.
If you edit an attribute of resource type, this will affect all of the resources classified this type.
For instance, if you set the MonitorInterval attribute value that defines monitoring periods to 30 seconds, the NIC resources defined as public and private1 will be all switched to 30 seconds.
Resource Type Attribute
Each resource type has a different attribute value. (ex. Despite the same attribute name, it can have a different value depending on the resource.)
In addition, if you change the attribute of resource type, it will be applied to all the resources of the type within the group.
