1.9.1 Locate a Compute Node that is down

Any node that shows a state of "unavail" or "unreach" is potentially down and should be

checked by a system administrator. In order to determine the state of nodes on the cluster, the

tools should be used.

Using the Clusterware Pro V5.1 Web Interface

The default hosts view is a table showing information about your hosts' resources. The default

view is accessed from:

View->Details

There are two different indications of health and status: State, and Batch State.

State refers to the state of the host.

Batch State refers to the state of the host, and the state of the daemons

running on that host.

Using the Clusterware Pro V5.1 CLI

An overview of a nodes health can be obtained by looking at the Clusterware Pro status and

batch states of that node.
