To display the state of a service group on a system

• Type the following command:

  # hagrp -state [service_group] [-sys system]

To display the resources for a service group

• Type the following command:

  # hagrp -resources service_group

To display a list of a service group's dependencies

• Type the following command:

  # hagrp -dep [service_group]

To display a service group on a system

• Type the following command:

  # hagrp -display [service_group] [-sys system]
  

  If service_group is not specified, information regarding all service groups is displayed.

To display the attributes of a system

• Type the following command:

  # hagrp -display [service_group] 
  [-attribute attribute] [-sys system]

  Note that system names are case-sensitive.

To display the value of a service group attribute

• Type the following command:

  # hagrp -value service_group attribute

To forecast the target system for failover

• Use the following command to view the target system to which a service group fails over during a fault:

  # hagrp -forecast service_group [-policy failoverpolicy value] [-verbose]

  The policy values can be any one of the following values: Priority, RoundRobin, Load or BiggestAvailable.

  Note:

  You cannot use the -forecast option when the service group state is in transition. For example, VCS rejects the command if the service group is in transition to an online state or to an offline state.

  The -forecast option is supported only for failover service groups. In case of offline failover service groups, VCS selects the target system based on the service group's failover policy.

  The BiggestAvailable policy is applicable only when the service group attribute Load is defined and cluster attribute Statistics is enabled.

  The actual service group FailOverPolicy can be configured as any policy, but the forecast is done as though FailOverPolicy is set to BiggestAvailable.
