Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

is specified, output is written to
stdout.
cmrecovercl [-f] This command performs the recovery actions necessary to
start the recovery groups on current cluster. Care should be
taken before issuing this command. It is important to contact
the primary cluster site to determine if recovery is necessary
prior to running this command.
This command will perform recovery actions only for
recovery groups that are out of the maintenance mode (i.e.
enabled). If the specified recovery group for -g option is in
maintenance mode; the command will exit without
recovering it. When -c option is used; the command will
skip recovering recovery groups which are in the
maintenance mode.
This command can be issued from any node on the recovery
cluster. This command first connects to the Continentalclusters
monitoring package running on the recovery cluster. This
may be a different cluster node than where the
cmrecovercl command is being run. cmrecovercl
connects to the monitoring package to verify that the primary
cluster is in an Unreachable or Down state. If the primary
cluster is reachable and the cluster is Up, this command will
fail. Next, the data receiver packages on the recovery cluster
(if any) are halted sequentially. Finally, the recovery
packages are started on the recovery cluster. The recovery
packages are started by enabling package switching
globally (cmmodpkg -e) for each package. This will cause
the package to be started on the first available node within
the recovery cluster. The cmrecovercl command can only
be run on a recovery cluster. The cmrecovercl command
will fail if there has not been sufficient time since the primary
cluster became unreachable. This command is only enabled
after the time as configured via CLUSTER_ALARM
parameters has been reached. Once a cluster alarm has
been triggered, this command will be enabled and can be
run. The -f option can be used to enable the command after
the time as configured via CLUSTER_ALERT parameters
has been reached.
Options are:
-f The force option enables cmrecovercl to function
even though a CLUSTER_ALARM has not been
received.
cmrecovercl {-e | -d [f]
}-g <recovery group name>
This command moves a recovery group in and out of the
maintenance mode by disabling or enabling it. This
command should be run only on the recovery cluster.
Options are:
-e Moves a recovery group out of the
maintenance mode by enabling it.
-d [-f] Moves a recovery group into the maintenance
mode by disabling it. Use the -f option to
forcefully move a recovery group into the
maintenance mode when the primary cluster
status is unknown or unreachable.
