Resource fields
Table 16 Resource fields
Description Name
Physical or logical entity that is capable of being owned by a node, brought
online and taken offline, moved between nodes, and managed as a server
cluster object Name
Status of the resource: Normal (the resource state is online), Degraded (the
resource state is Unavailable, Offline, Online Pending, or Offline Pending), Status
Failed (the resource state is failed), and Other (unable to determine the resource
condition)
Collection of resources managed as a single server cluster object Group
Node on which a resource resides OwnerNode
Server cluster object used to categorize and manage resources that have similar
characteristics Type
Disk or drive on which the resource resides Drive
NOTE: A group must have a network name and an IP address associated with it for you to access
group resources. A group can be owned by any node in the cluster and can be moved by users
with
administrative rights for load balancing and other administrative purposes. When a failure
takes place, the entire group fails over, which prompts the cluster software to transfer all group
resources and data to a different node in the cluster. The resources and data in a transferred (failed
over) group are still accessible under the same network name and IP address, even after they have
been moved to a different node.
Cluster Monitor resource thresholds
Cluster resources use thresholds to trigger HP SIM events. The Disk resource sets thresholds for disk
capacity, and the CPU resource sets thresholds for CPU utilization.
Disk capacity thresholds
Use the Disk resource to collect disk capacity data. To access the Cluster Monitor - Node Resource
Settings page where the thresholds are set, select Options
→Cluster Monitor→Node Resource
Settings.
The threshold values you enter in the Settings for the Selected Resource section define the Minor,
and Major ranges for disk utilization on monitored nodes.
For each disk, there are four thresholds in pairs. The Minor and Major thresholds are associated
with a corresponding reset threshold. Utilization enters the Major range when it equals or exceeds
the Major threshold value. It remains in the Major range until it falls to or below the Major reset
value. Minor and Major reset thresholds behave similarly.
You can specify different thresholds for each disk in each node of a cluster.
CPU utilization thresholds
Use the CPU resource to collect utilization data for CPUs in a cluster. To access the Cluster Monitor
- Node Resource Settings page where the thresholds are set, select Options
→Cluster Monitor→Node
Resource Settings.
The threshold values you enter in the Settings for the Selected Resource section define the Normal,
Minor, and Major ranges for CPU utilization on the selected node.
For each CPU, there are four thresholds in pairs. The Minor and Major thresholds are associated
with a corresponding reset threshold. Utilization enters the Major range when it equals or exceeds
