Administering global service groups

Operations for the VCS global clusters option are enabled or restricted depending on the permissions with which you log on. The privileges associated with each user role are enforced for cross-cluster, service group operations.

See User privileges in global clusters.

 To bring a service group online across clusters for the first time

# hagrp -online -force

 To bring a service group online across clusters

# hagrp -online service_group -sys system [-clus cluster | -
localclus]
 
  The option -clus brings the service group online on the system designated in the cluster. If a system is not specified, the service group is brought online on any node within the cluster. The option -localclus brings the service group online in the local cluster.

 To bring a service group online on any node

# hagrp -online [-force] service_group -any [-clus cluster | -
localclus]
 
  The option -any specifies that HAD brings a failover group online on the optimal system, based on the requirements of service group workload management and existing group dependencies. If bringing a parallel group online, HAD brings the group online on each system designated in the SystemList attribute.

 To take a service group offline across clusters

# hagrp -offline [-force] [-ifprobed] service_group -sys system 
[-clus cluster -localclus]
 
  The option -clus takes offline the service group on the system designated in the cluster.

 To take a service group offline anywhere

# hagrp -offline [-ifprobed] service_group -any [-clus cluster |

-localclus]

The option -any specifies that HAD takes a failover group offline on the system on which it is online. For a parallel group, HAD takes the group offline on each system on which the group is online. HAD adheres to the existing group dependencies when taking groups offline.

 To switch a service group across clusters

# hagrp -switch service_group -to system [-clus cluster

-localclus]

The option -clus identifies the cluster to which the service group will be switched. The service group is brought online on the system specified by the -to system argument. If a system is not specified, the service group may be switched to any node within the specified cluster.

 To switch a service group anywhere

# hagrp -switch service_group -clus cluster

The option -clus identifies the cluster to which the service group will be switched. HAD then selects the target system on which to switch the service group.
