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 display the resources for a service group
|
hagrp -resources service_group
[-clus cluster_name | -localclus]
The option -clus displays information for the cluster designated by the variable cluster_name; the option -localclus specifies the local cluster.
|
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 [-nopre]]
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.
The option -nopre indicates that the VCS engine must switch the service group regardless of the value of the PreSwitch service group attribute.
|
To switch a service group anywhere
|
hagrp -switch service_group -any
[-clus cluster | -localclus]
The -any option specifies that the VCS engine switches a service group to the best possible system on which it is currently not online, based on the value of the group's FailOverPolicy attribute. The VCS engine switches a global service group from a system to another system in the local cluster or a remote cluster.
If you do not specify the -clus option, the VCS engine by default assumes -localclus option and selects an available system within the local cluster.
The option -clus identifies the remote cluster to which the service group will be switched. The VCS engine then selects the target system on which to switch the service group.

To switch a parallel global service group across clusters
|
hagrp -switch
VCS brings the parallel service group online on all possible nodes in the remote cluster.
