#### Section 2. Recovery Groups ####

#### ####

#### This section defines recovery groups--sets of Serviceguard ####

#### packages that are ready to recover applications in case of ####

#### cluster failure. Recovery groups allow one cluster in the ####

#### continental cluster configuration to back up another member ####

#### cluster's packages. You create a separate recovery group ####

#### for each Serviceguard package that will be started on the ####

#### recovery cluster when the cmrecovercl(1m) command is issued. ####

#### ####

#### A recovery group consists of a primary package running on ####

#### one cluster, a recovery package that is ready to run on a ####

#### different cluster. In some cases, a data receiver package runs ####

#### on the same cluster as the recovery package, and in some cases, ####

#### a data sender package runs on the same cluster as the primary ####

#### package.For rehearsal operations a rehearsal package forms a ####

#### part of the recovery group. The rehearsal package is configured ####

#### always in the recovery cluster. ####

#### ####

#### During normal operation, the primary package is running an ####

#### application program on the primary cluster, and the recovery ####

#### package, which is configured to run the same application, is ####

#### idle on the recovery cluster. If the primary package performs ####

#### disk I/O, the data that is written to disk is replicated ####

#### and made available for possible use on the recovery cluster. ####

#### For some data replication techniques, this involves the use of ####

#### a data receiver package running on the recovery cluster. ####

#### In the event of a major failure on the primary cluster, the ####

#### user issues the cmrecovercl(1m) command to halt any data ####

#### receiver packages and start up all the recovery packages ####

#### that exist on the recovery cluster. ####

#### ####

#### During rehearsal operation, before starting the rehearsal ####

#### packages,care should be taken that the replication between the ####

#### primary and the recovery sites is suspended. For some data ####

#### replication techniques which involve the use of a data receiver ####

#### package, rehearsal operations must be commenced only after ####

#### shutting down the data receiver package at the recovery ####

#### cluster. Rehearsal packages are started using the ####
